Balancing machine is used for testing the rotor balancing instruments, according to the results of measurement calibration to improve balance the weight distribution of the rotor, the rotor running shaft vibration or reduce the forces acting on the bearing to the specified range.

Recently, the balanced application of changes brought to train potential we look below. According to dynamic balancing machine media stated: with running the ever increasing speed of the railways, the higher requirements in railway maintenance, wheel is an important component of trains running, wheel unbalance built up in running, but also for car-body vibration is one of the key factors. Analysis on causes of vibration of vehicle, mainly owing to the dynamic balancing of values, eccentricity and the same poor wheel diameter exceeding the limits, the same wheel diameter difference and eccentricity of the wheel shall be strictly controlled within the standard range.
