Motor rotor and spindle, crankshaft, turbine rotor, gyro rotor and escapement rotating parts in the manufacturing process, need to go through in order to smooth the normal operation of balance.

Universal joint balancing machine: coupling drive is the use of universal joints will balance the spindle and the rotor connected.

Spindle is a key unit of the high-speed machine tool, while the interference fit between spindle and motor rotor is one of the most important factors influencing the performance of the spindle unit.
