    Unbalance reduction ratio (URR) 95%
    Features
    • The drive motor uses a flat belt placed at the rotor’s center to keep rotation smooth and stable during testing.
    • An integrated drilling unit, controlled by PLC, moves across an 800 mm range on the beam with a 20 mm drill bit to perform unbalance correction directly above the workpiece.
    • Once measurement is complete, the drill automatically stops at the correction point, removing material on both balancing planes.
    • Drill depth is calculated after selecting the bit diameter and the density of the material, improving correction accuracy.
    • A printer is included for generating A4 reports of the test results.
    • An industrial vacuum system is provided to collect chips from the drilling process, keeping the workspace clean.

    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.
