The balancing machine is used to reduce vibrations of rotating bodies and performs balance measurement and correction for all existing rotating bodies. By achieving balance, there are benefits such as improved product performance and increased longevity. Additionally, a precisely balanced rotor can achieve stress-free high-speed rotation, thereby reducing environmental impact. In the horizontal balancing machine, rotors are measured individually, with a hard type for large rotors (approximately 1kg and above) and a soft type for small, high-speed rotating or assembly rotors. You can select based on a flowchart tailored to your application. **Features of the Hard Type:** - Measurement is possible simply by inputting the dimensions of the rotor with permanent scale calibration. No adjustment work is required for each workpiece. - Flexible expansion is possible, covering a wide range of weights by combining two different types. **Features of the Soft Type:** - No special foundation is necessary. It can be installed on floors two levels or higher. - Measurements are conducted at speeds higher than the resonance frequency, allowing for a higher upper limit of rotational speed, and angle errors do not occur due to rotor-dependent calibration. *For more details, please download the catalog or feel free to contact us.*
