Frequently Asked Questions

On-site (mobile) balancing service is the process of balancing large and difficult-to-move machines or parts in their own operating environment, without disassembly. This service provides a significant advantage, especially for heavy equipment like generators, fans, pumps, and motors. The disassembly, transport, and reassembly of such parts is a process that is both very costly and time-consuming. Thanks to on-site balancing services, production downtime caused by these operations is minimized and operational efficiency is maintained.

During the on-site balancing process, the machine's vibration levels are first measured using high-precision sensors. The expert team at MBS Balans Sanayi uses this data to calculate the amount and angle of the unbalance. Based on these calculated figures, weight is either added or removed (for example, by drilling) at the appropriate point on the part. After the correction is completed, the machine is run again, and the vibration levels are re-checked. This cycle is repeated until the vibrations are reduced to acceptable tolerance levels. The time to complete the process can vary depending on the part's initial unbalance condition and ease of access. This service not only ensures the continuous operation of facilities but also extends the life of machines and reduces the risk of failure.

Industrial balancing machines are sophisticated systems that work to eliminate unwanted vibrations and mass unbalances in a rotating part. Their core operating principle is based on vibration measurement and force analysis. When a part is mounted to the machine and begins to rotate, any unbalance in the mass distribution creates a centrifugal force. This force causes the part and its bearings to vibrate. The balancing machine detects and measures these vibrations using high-precision sensors (transducers). The detected signal is then transmitted to the machine's control unit.

The advanced software within the control unit processes the data from the sensors and calculates the exact amount of the unbalance (in grams or ounces) and its angular position (in degrees). This data is clearly displayed to the operator on a screen. Based on this information, the operator determines the most suitable method to correct the unbalance (adding or removing weight). After the correction is complete, the part is tested again, and this cycle is repeated until the residual vibrations are reduced to an acceptable tolerance level. Specialized software like the iBalancer, developed by MBS Balans Sanayi, makes this process faster and more intuitive, minimizing operator errors and ensuring the highest precision.

Balancing machines are sophisticated systems that operate by detecting vibrations caused by mass imbalance in a rotating part. Their basic operating principle is based on measuring the centrifugal force generated when a part rotates around its axis of rotation. If the part is unbalanced, this force creates vibrations on the bearings. The machine's sensitive sensors (transducers) detect these vibrations and send them to the control unit as an electrical signal. These signals are synchronized with the part's rotation speed and angle, and the exact amount of imbalance (in terms of weight) and its angular position are calculated.

This obtained data provides guidance for correcting the part's imbalance. Based on the information displayed on the screen, the operator applies one of the following methods: adding weight (e.g., by welding or bolting) or removing weight (e.g., by drilling or milling) to the area directly opposite the imbalance. After this process, the part is rotated again to check the remaining imbalance. This cycle continues until the vibrations fall within an acceptable tolerance level. The advanced software we use at MBS Balans Sanayi automates this process, making it both faster and more precise.

Balancing machines are available in various types, specifically designed for industrial needs. Each machine type is customized for different part sizes, weights, and applications. Here are the most common types of balancing machines and their areas of use:

Horizontal Balancing Machines: Ideal for balancing long and heavy parts. They are used to correct both static and dynamic imbalances in parts such as large rotors, shafts, and generator shafts.

Vertical Balancing Machines: Designed for vertically balancing short, disc-shaped parts around their axes. These machines are highly effective for fans, brake discs, flywheels, and pulleys.

Turbo Balancing Machines: Used for precision parts operating at high speeds, such as turbochargers and turbine components. These machines test parts at very high speeds, ensuring the most accurate balancing at operating speeds close to operating speed.

Shaft Balancing Machines: Developed specifically for the precise balancing of long, cylindrical shafts and cardan shafts. They are widely used in the automotive and shipbuilding industries.

Automatic Balancing Machines: Ideal for mass production lines requiring fast and precise balancing. These machines automatically measure and correct unbalance, minimizing human intervention and increasing production efficiency.

Additionally, specialized equipment such as flowbench machines (flow performance testing), portable wastegate testers, and optional units that extend the functionality of balancing machines are also available for specific applications. At MBS Balans Sanayi, we offer solutions for all your balancing needs with our wide range of machines. Consult our expert team about your part specifications and production goals to determine which machine type is best for you.

Static balancing and dynamic balancing are two different methods for correcting a part's unbalance, and their fundamental difference is based on whether the part is stationary or in motion. Static balancing ensures the part's weight is evenly distributed around its axis of rotation while it's at rest. This process is done by placing the part on a knife edge or bearings, with the goal of making the center of gravity coincide with the geometric center. Static balancing can be sufficient for disc-shaped parts that are short in length relative to their diameter and rotate at slow speeds. This single-plane balancing prevents the heavy spot of the part from settling at the bottom when it's at rest, but it doesn't correct dynamic unbalances that occur during rotation.

On the other hand, dynamic balancing aims to eliminate the vibrations and forces a part generates while rotating. In a high-speed rotating part, an unbalance in mass distribution creates unbalanced forces (centrifugal force and couple force) in at least two different planes. These forces cause the part to wobble and vibrate excessively during rotation. Dynamic balancing requires corrections to be made in at least two different planes to eliminate these forces. For this reason, dynamic balancing is critically important for high-speed parts like spindles, shafts, and long rotors. At MBS Balans Sanayi, we perform these complex balancing procedures with the highest precision using our dynamic balancing machines, ensuring parts have a long and efficient service life.

Balancing adjustment is the process of aligning a rotating part's center of gravity with its axis of rotation. This process aims to minimize the centrifugal forces and vibrations that originate from unbalances in a part's mass distribution, which can lead to serious problems at high speeds. If a part isn't perfectly balanced, it places excessive stress on bearings and machine components during rotation, which can cause noise, energy loss, premature bearing wear, and even machine failure.

A proper balancing adjustment not only ensures the part runs more stably and quietly but also significantly increases the machine's overall lifespan and efficiency. The balancing process is performed by determining the amount and location of the unbalance in a part, then adding or removing weight at the appropriate points. This process is vital for critical components that operate at high speeds, such as fans, turbines, and motor rotors. At MBS Balans Sanayi, we provide advanced balancing solutions to ensure that every rotating part is adjusted with the highest precision.

Using a balancing machine is a meticulous process that needs to be followed precisely to eliminate vibrations from rotating parts. To ensure the machine operates correctly and you get the best results, you should follow these steps:

1. Part Preparation and Mounting: First, the part to be balanced is cleaned and mounted correctly onto the machine using appropriate adapters. It is critical that the part is stable during the balancing process and that the vibration sensors are placed with precision.

2. Unbalance Measurement: Once the part is ready, the machine is started. The machine's sensitive sensors measure the vibrations that occur during rotation and transmit this data to the control unit. The software in the control unit calculates the exact amount of unbalance (e.g., in grams) and its angle. This data is clearly displayed on the machine's screen.

3. Correction Process: Based on the data obtained, a correction is made to eliminate the unbalance. This is done either by adding weight directly opposite the unbalance (via welding, bolts, etc.) or by removing material from the area of unbalance (via drilling, milling, etc.). The method used depends on the type of part and the amount of unbalance.

4. Verification and Repetition: After the correction is complete, the part is run again, and the residual unbalance is measured. This cycle is repeated until the part's vibration levels fall to within acceptable tolerance values. Modern balancing machines offer algorithms and user-friendly interfaces that speed up this process. MBS Balans Sanayi's software optimizes this procedure, ensuring you get accurate results at every step.

Using a balancing machine is more than just a technical task; it's the most important way to ensure the machine operates safely and efficiently.

Balancing adjustment is a critical process that makes a part more stable by correcting its mass unbalance. This procedure consists of two main stages: measurement and correction. First, the part to be balanced is placed on a balancing machine and rotated. The machine's sensitive sensors detect the vibrations that occur during the part's rotation and use this data to calculate the exact amount of unbalance (in weight) and its angular position. This stage is vital for determining where and how much unbalance is present in the part.

After the measurement stage, the correction stage begins. In this stage, one of two main methods is used to correct the unbalance: adding weight or removing weight. Based on the calculated data, an appropriate weight is either added directly opposite the area of unbalance (e.g., with welding, bolts, or adhesive) or material is removed from the area of unbalance (e.g., with drilling or milling). This process minimizes vibrations by bringing the part's center of gravity into alignment with its axis of rotation. After the correction is completed, the part is tested again, and this cycle is repeated until the residual unbalance falls to within acceptable tolerance levels. Advanced software like iBalancer, used by MBS Balans Sanayi, makes this process faster and more precise.

Balancing tolerance is a critical value that specifies the maximum permissible residual unbalance in a part. In other words, it is the highest level of unbalance allowed to remain in the part after the balancing process is complete. This value is determined based on the part's rotational speed, application, and overall operational requirements. For example, a very low and tight tolerance is needed for a high-speed turbine rotor, while a looser tolerance may be acceptable for a slower-operating fan. This tolerance is typically defined using international standards such as ISO 1940 and ensures the part operates safely and efficiently.

Determining the correct balancing tolerance and adhering to it is vital for a machine's longevity. Exceeding the tolerance increases the part's vibration levels, leading to rapid wear of bearings, shafts, and other machine components. Consequently, maintenance costs rise, energy efficiency drops, and potential failure risks emerge. Conversely, a part balanced to the correct tolerance level operates more quietly, more efficiently, and more safely. Therefore, balancing tolerance is not just a technical detail but a guarantee of machine performance and reliability.

Dynamic balancing machines are basically divided into two main categories based on their bearing systems: soft-bearing and hard-bearing machines. This classification determines how the machine measures unbalance and which types of applications it is best suited for. Soft-bearing balancing machines have a flexible structure at the support points where the rotor is mounted. This flexibility allows them to measure the amplitude of vibrations caused by unbalance. These types of machines generally operate with high precision at lower speeds and are particularly ideal for delicate rotors. While soft-bearing machines can be more complex to install and calibrate, they offer exceptional accuracy in certain frequency ranges.

On the other hand, hard-bearing balancing machines use a rigid, or rather inflexible, structure at the support points where the rotor is mounted. These machines work by measuring the force created by unbalance on the bearings. Their strong and durable construction makes them preferred in industrial environments. Hard-bearing machines can accommodate a wider range of rotor weights and sizes and can be quickly adjusted for different rotors without requiring calibration. This makes them extremely efficient in mass production and when balancing various parts. At MBS Balans Sanayi, we offer both soft- and hard-bearing solutions tailored to our customers' needs and guarantee the highest performance using the latest versions of both technologies. The type of machine that's right for you depends on the characteristics of the parts you'll be balancing and your production requirements.

The balancing process in horizontal balancing machines consists of a series of steps that are not as complex as the part itself but require a great deal of attention. First, the rotor to be balanced is correctly and securely placed on the machine's bearings using appropriate mounting fixtures and adapters. This step is key to an accurate measurement because the part must be supported in the machine just as it is in its actual operating conditions.

After the part is secured to the machine, the rotor begins to spin. The machine's sensitive sensors detect the vibrations and forces that occur during rotation. This data is analyzed by the machine's advanced software to precisely determine the amount and angle of unbalance in the two planes of the rotor. This information clearly shows the operator how much weight needs to be added or removed and at what point. Once the correction is complete, the part is spun again to check the residual unbalance. This cycle continues until the part falls within the tolerances specified by international standards like ISO 21940. This process ensures the part operates more efficiently and has a longer service life.

The balancing machines we produce at MBS Balans Sanayi are designed for use in a very wide range of industrial applications. This is because every rotating part needs to be balanced for efficient and safe operation. Therefore, our machines are widely used in many different sectors, from automotive to aerospace and from energy to marine industries.

For example, our machines are used in the automotive industry to balance critical parts like engine flywheels, brake discs, and turbochargers, while in aerospace, they are indispensable for aircraft engine turbines and fans. In the energy sector, we offer solutions for wind turbine rotors and generators, and in machinery manufacturing, for pumps, compressors, and motor shafts. Our machines ensure the precise balancing of a wide variety of parts used in these different sectors, such as rotors, fans, turbines, shafts, propellers, and drums. We cater to all industries with both our automated solutions, which keep pace with the speed of mass production lines, and our flexible machines designed for the needs of special projects.

Choosing a balancing machine is a critical decision for your business's efficiency and production quality. A wrong choice can lead to losses in both time and money. Therefore, there are several key factors you should consider when buying a balancing machine. Taking these into account will ensure you get the best return on your investment.

First, you must consider the weight and dimensions of the rotor you will be balancing. The machine's maximum and minimum weight capacity, along with your rotor's diameter, will determine if the machine is suitable for you. You also need to decide on the right level of automation by considering your production line's features and needs. If you are doing mass production that requires high speed and precision, CNC automated machines will be ideal for you.

The machine's drive system is another important factor. You must determine which is more suitable for your rotors: a standard belt drive or a shaft drive system. Finally, the support and services you receive after the purchase are at least as important as the machine itself. Do not neglect to get detailed information about the technical support, spare parts supply, and warranty conditions offered by the machine manufacturer. At MBS Balans Sanayi, we would be happy to help you with all these matters and find the most suitable solution for your business.

Dynamic balancing is a critical process used to prevent unwanted vibrations and mechanical stresses in rotating machinery. Simply put, it's the process of aligning the center of mass of a rotating part with the axis of rotation. Imbalances in the mass distribution of a rotating part create centrifugal forces at high speeds. This force can overload bearings, shafts, and other machine components, leading to serious damage, energy loss, and, most importantly, operational noise. Therefore, dynamic balancing is essential for extending machine life, improving work safety, and maximizing productivity.

This balancing process not only aligns the part's center of mass at a single point but also eliminates imbalances in two different planes. This balances the moments and coupled forces generated during rotation, ensuring more stable and quiet machine operation. At MBS Balans Sanayi, we perform this process precisely with our state-of-the-art balancing machines, helping our customers' machines operate at maximum performance and with minimal risk of failure. Correct dynamic balancing reduces wear on machine components, lowers maintenance costs, and improves production quality.

Choosing a balancing machine's capacity is a critical decision for the efficiency and safety of your work. This choice directly depends on the weight and dimensions of the parts you will be balancing. If you are working on small, delicate parts, a lower-capacity machine will be sufficient. However, if you need to balance large and heavy rotors, shafts, or turbine parts, you should consider machines with capacities of 1-5000 kg or higher. Thanks to the wide range we offer at MBS Balans Sanayi, you can find a solution to suit every weight and size requirement. It's important to keep in mind that the stated capacity of the machine may not offer the same accuracy across all weight and speed ranges. Therefore, the weight of your heaviest part and the desired accuracy should guide you in determining the right capacity.

Another important factor to consider when choosing capacity is your production volume. If you are a mass-production company, CNC-controlled balancing machines, which minimize manual intervention and enable fast processing, will maximize your productivity. If you're balancing parts of various sizes and weights, selecting your machine's capacity based on your largest part will also meet your future needs. This way, you can easily handle multiple jobs with a single machine. MBS Balans Sanayi experts are ready to help you select the machine with the most suitable capacity by analyzing your specific needs. Choosing the right capacity is a smart investment that supports not only your current needs but also your future growth goals.

Click to choose the balancing machine that best suits your job capacity.

Choosing the right MBS Balans Sanayi machine for your balancing application directly impacts the efficiency and quality of your production processes. To make the right decision, you must first clearly define your needs. The right machine depends on the type of balancing task you're performing, the size and weight of the parts, the level of precision you need to achieve, and your production volume. For example, if you have small disc-shaped parts, vertical balancing machines are ideal. If you need to balance long, cylindrical, and heavy shafts, horizontal balancing machines offer a more suitable solution. The wide range of machines we offer at MBS Balans Sanayi are designed to meet these diverse needs, and each machine type serves a specific purpose.

Factors such as budget, production capacity, and adjustment method also play a decisive role in machine selection. For example, our turbo balancing machines provide the most accurate results for components such as turbochargers or turbines that require high precision. We also have shaft balancing machines specifically designed for large and heavy shafts. Remember, the most expensive machine is not always the most accurate. The key is to find the right solution that will meet the specific requirements of your operation, ensure long-term efficiency, and provide a significant return on your investment. Our expert team is ready to analyze your needs and guide you in selecting the most suitable MBS Balans Industry machine.

The software used in balancing machines is like the heart of the machine; it directly affects everything from measurement precision to user experience. Advanced software significantly speeds up the balancing process by calculating the amount and location of unbalance quickly and accurately. This eliminates the need for manual calculations by the operator, increasing production efficiency.

Furthermore, the software's compliance with international standards (such as ISO 21940) ensures that measurement results are reliable and repeatable. This is vital, especially for balancing precision parts and in quality control processes. Features like user-friendly interfaces and multi-language support help operators use the machine more easily and efficiently. As a result, good balancing machine software doesn't just control a machine; it optimizes the balancing process, minimizes errors, and ensures the highest quality results are obtained. At MBS Balans Sanayi, we place great importance on using this type of advanced software in our machines.

A Vertical Shaft Impactor (VSI) is a special type of impact crusher designed for the high-speed, controlled crushing of hard and abrasive materials. These machines operate on the principle of a rotor spinning around a vertical axis. The rotor hurls the material that falls into it at a high velocity toward the outer perimeter of the machine. This impact causes the material to break against itself or against the outer wall. This autogenous crushing principle is an ideal solution for processing abrasive materials, such as high-silica stones, as it leads to less wear on the crusher.

Vertical shaft crushers are widely used in concrete plants for producing high-quality sand and aggregates, as well as in road construction and various mining applications. When compared to horizontal shaft crushers, they generally have lower operating and maintenance costs. They also offer advantages in energy efficiency because the material's self-crushing principle consumes less energy. The rotors of these types of crushers operate at high speeds, making their dynamic balancing critically important. At MBS Balans Sanayi, by correctly balancing the rotors of these crushers, we both extend the machine's lifespan and ensure more efficient and safer operation.

The Pelton turbine is an impulse-type water turbine used in hydroelectric power generation. It is named after the American inventor Lester Allan Pelton, who invented it in the 1870s. The basic operating principle of this turbine is based on a jet of water, coming from pipes under high pressure, being shot at very high speed onto a specially designed wheel with buckets. The kinetic energy of the water striking these buckets causes the wheel to spin, and this rotational motion is transferred to a generator to be converted into electrical energy. Pelton turbines operate with extremely high efficiency, especially in geographical conditions where there is high water pressure (high hydraulic head) but low water flow (volume).

One of the most important features of Pelton turbines is their simplicity and efficiency. Thanks to the unique shape of the buckets, almost all of the water's energy is converted into rotational motion, which provides high efficiency. At MBS Balans Sanayi, we know how critical the correct balancing of such turbines and their wheels is for efficient and vibration-free operation. The slightest unbalance in the turbine wheel can damage bearings, lead to energy loss, and negatively impact the system's overall performance. Therefore, balancing these critical parts is essential for safe and long-lasting operation.

Yes, at MBS Balans Sanayi, we produce machines specifically designed for balancing fans of various sizes and types. Because fans operate at high speeds, even the slightest unbalance can lead to significant vibration, noise, and energy loss. Therefore, correctly balancing them is of great importance for both operational efficiency and safety. The fan balancing machines we manufacture offer high precision and reliability to meet this specific need.

Our fan balancing machines can balance fans used in ventilation systems, air conditioning units, and industrial cooling systems, as well as larger industrial fans like those in power plants and large factories. Since every project has its own unique needs, the best approach is to determine the type, weight, and dimensions of your fan and contact us so we can offer you the most suitable solution. Our expert team will help you identify the best machine for your project's requirements.

The ISO 1940 standard is a globally recognized reference used to define the permissible unbalance levels for rotating parts. This standard establishes different quality grades (G-classes) based on the part's rotational speed and application. For example, a G2.5 grade is used for high-precision shafts and motor rotors, while a G6.3 grade is suitable for lower-speed and less-sensitive parts. This classification provides a clear guideline for engineers and manufacturers on how well a part needs to be balanced. It ensures that critical components operate safely and efficiently, while avoiding unnecessary costs and time spent on achieving excessively high precision.

ISO 1940 is an essential guide for ensuring quality and consistency in balancing processes. Choosing the correct G-class for a part's intended use extends bearing life, reduces vibration, and improves a machine's overall performance. At MBS Balans Sanayi, we design all our industrial balancing machines and services to comply with these international standards. Working with our customers, we determine the most appropriate ISO 1940 quality level for the specific needs of their parts, providing solutions that are both reliable and cost-effective.

The drive systems used in balancing machines directly affect the machine's performance and balancing precision. Essentially, two main drive systems are used: belt drive and shaft drive. Each system offers advantages depending on different rotor types and application requirements.

Belt drive systems rotate the rotor using a belt around its outer surface. The biggest advantage of this system is that it doesn't transmit vibrations from the drive motor to the rotor, thereby providing high measurement precision. It's ideal for small to medium-sized rotors with a smooth outer surface. These types of machines are frequently preferred for the precise balancing of parts such as motors, propellers, and discs.

Shaft drive systems, on the other hand, operate by connecting the motor directly to the rotor's shaft. This system is more suitable for large and heavy rotors because it can easily rotate and balance parts with high torque power. These machines are used for balancing parts like driveshafts, turbines, and heavy rotors, and they provide the necessary force to correct unbalances due to their high torque. When choosing the right drive system, you should consider factors such as the rotor's weight, size, and the desired balancing precision. You can get support from MBS Balans Sanayi to determine which system is best suited for your project.

MBS Balans Sanayi produces a wide range of special-purpose balancing machines for the automotive, aerospace, and general industrial sectors. Our product range includes solutions designed for balancing critical parts such as flywheels, brake discs, turbochargers, and driveshafts. However, we do not directly offer tire balancing machine production or services. Tire balancing is a process typically performed on vehicle wheels and differs from our company's area of expertise, which focuses on industrial balancing machines and the balancing of large, high-precision parts.

Our company's main focus is to provide solutions that extend the life of machines and parts used in industrial production processes, increase their efficiency, and minimize vibration. In this context, we aim to meet the unique needs of our customers with our industrial balancing machines and engineering solutions for special projects. Instead of tire balancing services, MBS Balans Sanayi provides professional support for more complex and high-precision applications.

It is completely normal to find a heavy spot on a static balancing stand even after successfully balancing a fan on a dynamic balancing machine. This doesn't mean there's a problem; rather, it highlights the fundamental difference between dynamic and static balancing. Static balancing stands only detect and measure mass unbalance in a single plane (i.e., static unbalance). These stands check if the part's center of gravity coincides with its geometric center. If the center of gravity isn't perfectly centered, the part will show a heavy spot on a static stand.

However, dynamic balancing machines operate differently. Dynamic balancing corrects both static unbalance and the dynamic unbalance (couple forces) that occur during rotation. These machines measure vibrations and forces while the rotor spins under conditions similar to its operational environment, which allows them to compensate for all of the part's unbalances. Therefore, a fan that has been dynamically balanced may still show a heavy spot on a static stand because the stand cannot detect that the dynamic unbalance has been corrected. The fan has been properly balanced for operation on its own bearings and its performance will not be affected. For this reason, a dynamically balanced part appearing heavy on a static stand means the process was successful, not that it failed.

Deciding whether to perform balancing in a single, two, or multiple planes depends on the part's geometry, mass distribution, and operational requirements. The most basic rule is that if the part's length is greater than its diameter, two-plane balancing is necessary. This is required to correct not only the unbalance at the center of mass but also the couple forces (moment unbalance) that occur during the part's rotation. Two-plane balancing is ideal for parts like shafts, spindles, and long rotors. This method simultaneously eliminates both static and dynamic unbalance, leading to more stable and vibration-free operation.

However, two planes are not always necessary. If your part is disc-shaped and its diameter is much greater than its length (for example, flywheels, pulleys, or some fans), single-plane balancing may be sufficient. In these parts, the mass unbalance is concentrated in almost a single plane, so a correction made in one plane yields the desired result. For much more complex parts, such as multi-stage pumps or long turbine rotors, multi-plane balancing may be required to completely eliminate the unbalance. Each section of these parts can contain its own unbalances, and these unbalances can affect each other. At MBS Balans Sanayi, we guide you in analyzing your part's characteristics to determine the most suitable number of balancing planes, ensuring you get the most accurate and efficient solution.

Plane separation is a critical term for balancing accuracy, particularly encountered in dynamic balancing operations performed in two planes. Simply put, it indicates how much the correction made to correct the imbalance in one plane affects the measurement results in the other plane when balancing in two planes. This effect is often referred to in the industry as cross effect or simply effect. In an ideal scenario, corrections made in one plane would be expected to have no effect on the other plane, but in practice, this is not possible. Therefore, a good balancing machine aims to minimize this effect, usually below 3%. A low cross effect allows the balancing process to be completed faster, more accurately, and more efficiently because the corrections in each plane do not disrupt each other.

Modern hard-bearing balancing machines use advanced mathematical models to address this issue. These machines simultaneously measure the imbalance in both planes and calculate independent correction values ​​for each plane by mathematically balancing the cross-effect. This allows the operator to effectively correct imbalance in both planes in a single operation, eliminating the need to handle each plane individually. At MBS Balans Sanayi, by utilizing this mathematical plane separation technology in our machines, we guarantee high-precision balancing results for even the most complex rotors. This technology simplifies the balancing process and saves time.

When choosing a vertical balancing machine, the drive system is at least as important as the machine's capacity, as it directly affects the precision and efficiency of the balancing process. The right drive system should be determined based on the characteristics of the part you are balancing and your production requirements. For example, belt-driven systems are ideal for small and medium-sized parts that require high precision. These systems minimize the transfer of engine vibrations to the part, enabling much more accurate and precise measurements. Belt-driven machines are frequently preferred in sectors where precision is paramount, such as the aerospace, automotive, and defense industries.

On the other hand, shaft-driven and self-driven systems meet different needs. Shaft-driven machines are more suitable for balancing heavy, large, or inherently unbalanced parts. These systems connect the part directly to the motor shaft, providing stronger torque and the ability to rotate heavy rotors in a balanced manner. Self-driven systems are generally the best solution for small, disc-shaped parts. Rotation of the part by its own motor or integrated mechanism ensures high speed and efficiency, especially in mass production. At MBS Balans Sanayi, we understand the advantages and disadvantages of each drive system and provide expert guidance in selecting the most suitable machine for you. By clarifying your needs, we can together find the most efficient and accurate balancing solution.

In the dynamic balancing process, supporting the workpiece at its mounting points to best simulate real-world operating conditions is crucial for the accuracy of the results obtained. This approach accurately reflects the stresses and forces the part will be exposed to in its operating environment, ensuring that the adjustments made on the balancing machine provide real benefits. When a rotor or shaft is mounted on a machine, the support it receives from the bearing points directly affects its dynamic behavior. If the balancing process is performed from different support points, imbalances due to mass distribution may manifest differently when mounted on the machine, resulting in inadequate balancing.

Therefore, at MBS Balans Sanayi, we always recommend balancing the part to be balanced using the bearing points in its actual mounting position or the areas closest to them. This approach recreates the actual operating conditions of the machine in a laboratory environment, ensuring the adjustments are permanent and effective. This minimizes vibrations generated by the part during operation, extends bearing life, and improves overall machine performance. Balancing from the correct support points is not only a balancing process, but also an engineering principle that ensures the safety and long-lasting operation of the machine.

In dynamic balancing, balancing the part at operating speed generally yields the most accurate results, but this is not always necessary. Thanks to modern balancing technology, dynamic balancing machines, especially those equipped with rigid bearings, can measure part unbalance with high precision even at much lower speeds. This is made possible by the balancing machine's capabilities. The measuring system detects the centrifugal force created by the mass imbalance in the part and calculates this imbalance in grams to millimeters. This measurement provides consistent results regardless of the speed at which the part is rotated. This allows parts operating at very high speeds to be balanced safely and with lower energy consumption.

Accurately measuring unbalance, even at low speeds, increases operational safety and speeds up the balancing process. Low-speed balancing corrections for fixed (rigid) rotors generally adapt to the rotor's operating conditions and are sufficient to achieve the desired balance. The modern machines we use at MBS Balancing Industry operate on this principle, ensuring the most efficient and safe balancing of components. However, in special cases, such as flexible rotors, testing may be necessary at speeds close to the rotor's operating speed. Except for these special cases, a standard dynamic balancing machine can measure unbalance independently of speed, significantly increasing the practicality and safety of the process.

Solid rotors are rotating parts that do not exhibit flexibility at operating speeds, meaning they do not change shape. These rotors operate stably because their operating speeds remain below their natural resonant frequencies. Unlike flexible rotors, the unbalance occurring in a solid rotor remains constant regardless of rotational speed. This allows balancing to be performed at a single speed, eliminating unbalance across the rotor's entire operating range. This feature makes them ideal for many industrial applications, such as pumps, motors, and fans operating at low and medium speeds. The stable structure of solid rotors simplifies the dynamic balancing process and ensures more reliable results.

Solid rotors are excellent candidates for single-plane or two-plane balancing operations. At MBS Balans Sanayi, we offer balancing machines that can correct unbalances in these types of rotors with high precision. Balancing a solid rotor is typically accomplished by measuring the mass distribution imbalance at the mounting position and adding or removing appropriate correction weights. This process minimizes vibration and noise while increasing the machine's overall efficiency, bearing life, and operational reliability. This stable structure of the solid rotors reduces maintenance costs and the risk of failure.

Flexible rotors are rotating parts that change shape (deform) when rotational speeds approach or exceed their natural resonant frequencies. Unlike rigid rotors, this causes the mass distribution to change with speed. Therefore, balancing at low speeds may be insufficient to eliminate the vibrations the rotor will experience at high operating speeds. Therefore, balancing flexible rotors is generally performed at speeds close to or above their operating speeds. This process is critical for accurately simulating the dynamic behavior of the part under operational conditions.

This dynamic nature of flexible rotors makes the balancing process more complex and often requires the application of multi-plane balancing techniques. These types of rotors are widely used in fields such as the energy sector (wind turbines), aerospace, and high-speed machinery. At MBS Balans Sanayi, we offer machines specifically designed for these demanding applications, with in-situ balancing and high-speed testing capabilities. On-site balancing eliminates potential errors resulting from assembly and disassembly by balancing the rotor on its own bearings and in its own operating environment, ensuring the most accurate results.

Accurately measuring the rotational speed of a workpiece in a balancing machine is a critical factor in ensuring the reliability of the results. Unbalance measurement relies on the relationship between the centrifugal force created by the mass distribution of the part and the angular position (phase angle) of this force. To perform this measurement accurately, the system must know the exact speed at which the part is rotating and generate a reference signal based on this speed. If the speed measurement is inaccurate, the location and magnitude of the unbalance will also be miscalculated, which can render the correction ineffective or even worsen the situation.

Especially in environments with abundant interference signals, such as factories, the inherent rotational motion of drive elements such as motors and belts increases the need for an accurate speed reference. Modern balancing machines operate by isolating these external factors and using sensitive sensors to accurately determine the instantaneous speed and phase angle of the part. This minimizes phase shifts and inaccurate measurements experienced in older systems. Ultimately, accurate speed measurement isn't just a technical detail; it's a fundamental requirement for ensuring the balancing process is completed accurately, quickly, and reliably. At MBS Balans Sanayi, we utilize advanced sensors and software in our machines to ensure this critical measurement is always performed with the highest accuracy.

The need for balancing machines capable of operating at a wide range of speeds depends entirely on the variety, size, and dynamic characteristics of the part to be balanced. Each part must be balanced at a different speed range, depending on its inherent structure and operating conditions. For example, for small, uniform parts used in mass production, machines operating at a fixed or narrow speed range are generally sufficient. These machines maximize efficiency by repeating the same process repeatedly. However, balancing parts such as large and heavy rotors encountered in industrial environments is much more complex. Because the mass distribution of these parts is not known in advance, balancing is generally started at low speeds and gradually increased speeds to minimize safety risks, collecting unbalance data.

This versatile speed adjustment is crucial for accurately balancing critical parts, especially flexible rotors. Because flexible rotors can deform as they approach their resonant frequency, such machines must be tested at different speeds. At MBS Balans Sanayi, we design our machines with the ability to operate at different speeds. This allows for both precise balancing of small, lightweight parts and safe balancing of large, heavy parts. This flexibility allows businesses to meet a wide range of balancing needs with a single machine, reducing investment costs and increasing operational efficiency.

Placing the dynamic balancing machine on a solid foundation is absolutely essential, a critical step that directly affects the machine's performance, measurement accuracy, and longevity. A balancing machine detects even the slightest vibrations caused by the rotating part and calculates the remaining unbalance based on these vibrations. If the machine itself is subjected to vibrations or vibrations caused by external factors, this will distort the measurements and lead to erroneous results. Therefore, the ground on which the machine will be installed must be vibration-free, stable, and stable. Otherwise, the signal from the part's unbalance will be mixed with environmental noise and vibration, making accurate analysis impossible.

A solid foundation allows the machine to absorb its own weight and any dynamic loads that may occur during operation, enabling measurement systems to operate with the highest precision. This is also crucial for occupational safety. At MBS Balans Sanayi, we place great emphasis on this fundamental principle during the installation of our machines. We provide our customers with technical support regarding the proper ground preparation for the efficient and accurate operation of their machines. A balancing machine mounted on a correct foundation not only provides precise results, but also reduces the need for maintenance and extends operational life.

The unbalance reduction ratio is one of the most important indicators of a balancing machine's efficiency and effectiveness. This ratio expresses the percentage reduction in unbalance measured on the rotor before the balancing process. Simply put, it's a measure of how much initial unbalance you've eliminated. A high unbalance reduction ratio indicates the accuracy and performance of your machine. For example, reducing an initial unbalance of 50 grams to 5 grams at the end of the balancing process means you've achieved a 90% reduction ratio. A good ratio, accepted in the industry and representative of efficiency, is generally 90% or higher.

This ratio is directly related not only to machine quality but also to the accuracy of the process. Adding or removing the correct correction weight at the correct location increases this ratio. At MBS Balans Sanayi, the machines we produce aim to achieve high reduction ratios by minimizing unbalance even in a single balancing operation, thanks to high-precision measuring systems and powerful software. This saves our customers time and ensures their rotors are operating at peak performance. A high unbalance reduction ratio increases overall machine efficiency, reduces vibration, and extends bearing life, providing significant long-term benefits.

Unbalance units are used to determine the amount and location of mass imbalance in a rotating part. In its most basic form, these units are obtained by multiplying the mass by the radius. This indicates not only the magnitude of the imbalance but also the distance from the center of rotation of the imbalance. For example, a 10-gram mass imbalance 50 millimeters from the center of rotation creates an imbalance of 500 grams-millimeters (gmm). This unit, gram-millimeter (gmm), is one of the most commonly used units of measurement and is generally preferred for small and medium-sized parts.

However, different units may be used depending on industrial applications and the measurement systems used. For example, units such as kilogram-meter (kgm) or meter-gram (mgm) may be preferred for larger parts. In the United States and some other countries, imperial units such as ounce-inch (oz-in) or pound-inch (lb-in) are used. All of these units are based on the same basic principle: multiplying the unbalanced mass by its distance from the axis of rotation. This allows us to precisely express the magnitude of the unbalance and plays a critical role in determining the extent of correction required for the balancing process. At MBS Balans Sanayi, we support all of these units in our machines, in accordance with various industry standards and customer requirements.

An ISO Test Rotor is a special reference part, manufactured in accordance with international standards, used to test the accuracy and performance of dynamic balancing machines. It is an indispensable tool for calibrating a balancing machine and verifying that it is making accurate measurements. This rotor has specific points where known weights can be precisely added and removed. This allows the balancing machine's measurement results to be compared with the known weight values added to or removed from the rotor. This test determines the machine's measurement precision and overall accuracy.

Conducting these tests in accordance with the ISO 2953 standard guarantees the reliability and consistency of the results obtained. The ISO Test Rotor is used not only during the initial setup of a newly purchased machine but also during periodic maintenance and whenever it is necessary to ensure the machine is functioning correctly. At MBS Balans Sanayi, we ensure our machines are tested and calibrated to ISO standards before they leave the factory. This way, we aim to offer our customers the highest level of performance and reliability. The ISO test rotor is a performance benchmark that indicates how reliable a balancing machine is, not just physically, but also in terms of its measurement quality.

In dynamic balancing, measurements taken at different speeds are expected to yield the same unbalance value, because unbalance is a vector quantity related to the part's geometry and mass distribution, independent of rotational speed. In other words, the unbalanced mass of the part and its distance from the center of rotation remain constant regardless of rotational speed. Therefore, theoretically, whether you balance a part at 100 rpm or 1000 rpm, you should obtain the same unbalance value. This principle certainly applies to solid rotors, and modern, high-precision balancing machines are designed to operate according to this principle. These machines guarantee that the results remain consistent, within the specified tolerance range, even when measured at different speeds.

However, in practice, small differences can occur during measurement due to factors such as mechanical vibrations within the system, sensor noise, or slight deflections of the rotor at very high speeds. These differences are directly related to the machine's measurement accuracy and quality. High-quality rigid bearing balancing machines can tolerate such small variations and deliver consistent and reliable results, even when measuring at different speeds. At MBS Balancing Industry, we utilize advanced sensor and software technologies to ensure this consistency in our machines. This ensures users can achieve accurate and repeatable results, regardless of the speed at which they balance their parts.

If the machine still exhibits a high degree of unbalance and angle shift despite the added weight, this usually indicates that the correction was performed at the correct location but at the wrong level. Unbalance is a vector quantity that not only has a magnitude but also a direction. In other words, determining the location of the weight to correct rotor imbalance is as critical as determining the amount of weight needed. If you add the correct amount of weight at a point even a few degrees off the calculated angle, you won't completely correct the rotor's imbalance. Instead, you'll add new imbalance to the existing one. This will cause the machine to recalculate the amount and angle of unbalance, resulting in a result that differs from the initial measurement.

To resolve this issue, you should proceed based on the new measurement taken by the machine after the initial balancing operation. MBS Balans Sanayi machines can guide you in such cases by precisely determining the remaining unbalance and the new angle. Based on this new data, you can eliminate the remaining imbalance by making a second adjustment at the correct amount and location. Remember, balancing is not a one-time intervention, but rather a gradual process that must be repeated until the correct result is achieved. The correct positioning of the added weight is key to successful balancing, and in these cases, the best approach is to act without haste and rely on the machine's new data.

If you want to perform balancing before a critical job but lack calibration and theory knowledge, there's no need to worry. In this case, the safest and most practical method is to work with an accuracy of half the balancing tolerance. For example, if your part's acceptable tolerance is 50 gmm, you can set the machine with a remaining imbalance target of 25 gmm. This approach minimizes potential risks by reducing the part's imbalance level to a reasonable range. This presetting ensures you've reached the correct reference point and balances the part well below the accepted tolerance.

Following this process, you should carefully check the remaining imbalance amount and angle before performing any corrections. If the remaining imbalance is at or below this predetermined half-tolerance, the process is considered successful. At MBS Balans Sanayi, our machines, with their user-friendly interfaces and automatic calculation capabilities, make it easy to take the right steps even in such situations. Our machine's sensitive sensors and software clearly display the remaining imbalance and angle, so you know what to do at each step. This practical method compensates for a lack of theoretical knowledge, enabling you to achieve successful and safe results in your critical tasks. However, it's important to remember that for the most efficient and accurate long-term results, the best approach is to fully calibrate the machine and learn proper balancing principles.

Despite balancing the part within tolerances, there could be several root causes for high vibration after assembly. This doesn't mean the balancing process was unsuccessful; rather, it indicates that the source of the problem lies outside the balancing process. Dynamic balancing addresses the internal mass imbalance of the part, but other components or incorrect assembly methods used during assembly can directly affect the vibration level of the final system. One of the most common causes is the use of poor-quality or worn bearings. Even the slightest damage or backlash in the bearings can lead to irregular rotation and significant vibrations during rotation. These vibrations are mechanical vibrations that cannot be eliminated by balancing.

Another important reason is that the adapters or couplings used in assembly are out of tolerance. Geometric differences between the adapters used in the balancing machine and the adapters used in the final system can cause the part to rotate smoothly in the machine but off-center during assembly. This invalidates the balancing process. At MBS Balans Sanayi, we always recommend our customers use high-quality adapters manufactured to precise tolerances and perform assembly operations with the utmost care. Remember, the performance of the final product depends not only on the balance of a single component but also on the fit and quality of the entire system. Therefore, it's important to carefully inspect bearings, adapters, and other assembly components when experiencing high vibration.

Determining the allowable unbalance or tolerance for a part is a critical step in ensuring the overall performance, lifespan, and safety of the system in which that part will operate. This tolerance value should be determined primarily by the part's designers or end users, as they best understand the speed, load, and criticality at which the part will operate. For example, the tolerance for a jet engine rotor will be much stricter than that of an electric fan motor. The allowable tolerance also directly impacts factors such as bearing life, noise level, energy consumption, and the overall operational reliability of the machine. Therefore, knowing the correct tolerance before starting the balancing process is crucial.

If you don't have this information or want to define a standard, you can refer to international standards such as ISO 2953. This standard defines acceptable balancing quality grades (e.g., G2.5, G6.3) for different applications. At MBS Balans Sanayi, we offer our customers software and consulting services based on these standards, calculating the most appropriate tolerance based on the part's characteristics (weight, speed, etc.). This allows you to determine the correct starting point and ensure your part operates at the highest efficiency and safety levels. Remember, the right tolerance represents the ideal balance: neither too tight, which would increase costs, nor too loose, which would decrease performance.

The best compensation method for correcting unbalance in a rotor depends on the amount of unbalance, the part's geometry, and its operational requirements. There are two main methods: adding weight and removing weight. When dealing with a minor unbalance, removing a small amount of material from the part can be a more practical solution. Methods like drilling, milling, or grinding are typically used for this. These techniques are generally ideal for small and delicate parts because they allow for precise, millimeter-level adjustments to eliminate unwanted vibration. However, it is crucial not to damage the part's physical integrity during these operations or cause structural weakness. Excessive material removal can compromise the part's strength.

On the other hand, if there is a significant rotor unbalance or if removing material is not feasible, adding weight is the safest and most effective method. In this approach, a weight, calculated by the machine, is added directly opposite the point of unbalance. This weight is usually secured to the part by welding or mechanical fasteners (screws, rivets, etc.). The weight addition method directly corrects the unbalance by shifting the part's center of gravity and avoids unnecessarily weakening the part. At MBS Balans Sanayi, with our machinery and expertise supporting both methods, we guide you in determining the most appropriate and safe compensation method for your part. Choosing the right method ensures not only the success of the balancing process but also the reliability and longevity of the part.

In the dynamic balancing process, the number of compensation points you use for weight is directly dependent on the part's geometry and dynamic characteristics. For standard dynamic balancing, compensation weights are typically used in at least two different planes to correct the mass unbalance of the rotating part. This approach is critical not only for eliminating unbalance at the center of mass but also for correcting moment unbalances that occur during rotation. Two-plane balancing is a sufficient and most effective solution for most rotor and shaft-type parts.

However, the balancing process may require additional points for more complex parts. For example, with wide and segmented fans or complex rotors consisting of multiple components, weights may need to be distributed across different points to completely eliminate unbalance. In such cases, using more compensation points allows for a more effective distribution of the unbalance and minimizes the final vibration. As a result, the physical structure and operating conditions of the part must be considered to determine the correct number of compensation points. At MBS Balans Sanayi, we are ready to provide you with technical support to determine the most accurate compensation method and number of points.

Technically, it is not possible to achieve "zero grams, zero degrees" balancing in the dynamic balancing process. This is because every rotor or part has a minimal mass unbalance due to manufacturing and machining tolerances. This unbalance can never be completely zeroed out. In addition, there is always a certain margin of error inherent in the precision of the measurement devices, sensors, and software used. Therefore, the balancing process aims not to completely eliminate a part's unbalance, but to reduce it to a predetermined tolerance range.

For example, if a part's tolerance is set at 20 gmm, the remaining unbalance after balancing can be any value between 0 and 20 gmm. This effectively means the part is "zero balanced" in a practical sense, as the remaining unbalance is below the acceptable level for operational requirements. The process is finalized by positioning this residual unbalance at an angle that keeps it within the determined tolerance. At MBS Balans Sanayi, our machines are designed to achieve these tolerance levels with high precision. This approach not only ensures you get the most accurate results but also increases your production efficiency by preventing unnecessary time and cost loss.

It's quite normal to see a very low unbalance value and a high angle simultaneously during a balancing procedure. This is usually an indication that the part is very well balanced and the remaining unbalance is at an acceptable level. Since unbalance is a vector quantity, it has both a value (magnitude) and a direction (angle). If the unbalance value is very close to zero, the machine attempts to measure the angle of a very small remaining unbalance. In this case, even a minor measurement error or environmental noise can cause the angle to appear as a random value.

This situation does not mean the machine is malfunctioning; on the contrary, it indicates that the process has been completed with precision and the part is within its tolerance range. The residual unbalance is so minute that even small imperfections or surface roughness on the part can affect the machine's angle measurement. What's important is that the unbalance value you get is below the acceptable tolerance set for the part. If the value is within tolerance, the part is considered balanced and can be used safely, regardless of the angle. At MBS Balans Sanayi, our machines clearly demonstrate this, allowing the user to understand that the result of the procedure is reliable.
