Balancing machine is a machine that measured unbalance the size and position of a rotating object. According to the balancing machine measuring on rotor unbalance correction can improve the mass distribution of the rotor relative to the axis, causes the rotor to spin with vibration or vibration force acting on the bearing is reduced to within the allowed range. Therefore, the balancing machine is to reduce vibration and improve performance and improve the quality of the essential equipment.

In General, the measurement and correction of the unbalance of rotor balancing includes two steps, balancing machine is mainly used for unbalance measurement, and the volume of imbalances correction is often through the drilling machines, milling machines, and other auxiliary equipment, spot welding machine, or hand-finished.
