    Auto-Positioning Balancing Machine

    Dynamic balancing machine with automatic positioning for workpieces with diameter of up to 800mm and weight of 5-100kg

    These automatic positioning balancing machines combine precision engineering, intelligent control, and software-based data processing. They are designed to measure and correct rotor unbalance with high accuracy. By analyzing data from the measuring system, they automatically locate the unbalance position, removing the need for manual angle finding. Thanks to their automatic positioning function, they can be used across a wide range of rotors that require precise balancing.

    Applications

    Widely used for dynamic balancing of motor rotors and other long-shaft components. Typical applications include separator rotors, oil press rotors, rolls, paperboard machine rotors, crushers, and a variety of agricultural machinery rotors such as straw returning and corn harvesting machines.

    Balancing machines are instruments that indicate if a rotating component, such as a rotor or fan, rotates in an unbalanced manner. If the component wobbles or vibrates a lot, the balancing machine will point out the imbalance so it can be corrected. The importance of balancing is directly related to the longevity of the rotating component and how well the component functions.

    Soft-bearing machines use flexible supports, making them sensitive to very small vibrations and suitable for lighter or smaller parts that require high accuracy. Hard-bearing balancing machines, on the other hand, use more rigid supports, so they are more suitable for larger and heavier rotors. Hard bearing balancing equipment may be less sensitive to tiny vibrations, but they are easier to set up and give reliable results across a wider range of workpieces.

    Balancing machines are used to rotating parts such as motor rotors, impellers, fans, flywheels, clutches, gears, pulleys, and brake drums. By correcting unbalance, they help reduce vibration, extend service life, and keep production running more smoothly.

    Balancing machines can be configured with belt drive, universal joint drive, or self-drive. Belt drive is usually chosen for smaller rotors that require accuracy, while universal joint drive delivers higher torque and is safer for heavier parts. Self-drive designs are used when the workpiece can rotate under its own power.

    Accuracy may be affected by operator handling, incorrect markings, or mismatched correction points. Technical issues such as damaged sensors, loose connections, or electronic failures can also play a role. Regular calibration and proper setup help keep results consistent.
