Generating an unbalanced rotor during its rotation on its own support structure and the rotor of a pressure and cause vibrations. Therefore, the rotor balancing is very necessary. Vertical balancing machine rotor balancing is to check the status under rotation, balancing role is: 
● improve the quality of its products constituted rotor 
● reduce noise 
● reduce vibration 
● Improved support member (bearing) trial life 
● Reduce the user's discomfort 
● reduce the power consumption of the product
