The balancing machine is divided into soft support and hard support. Compared with the two, the swing frame of the soft support balancing machine is relatively soft. During the process of starting and stopping the transmission shaft, the swing frame of the soft support will have very obvious vibration, while the swing frame of the hard support does not have this phenomenon.

If the weight reduction rate of the balancer is relatively high, it can complete the balance with less rotation times and work faster.

There are three factors affecting the weight loss rate:

1. Whether the calibration of the balancing machine is accurate.

2. Whether the weight and position of the balance weight placed during operation are accurate.

3. The clearance between the transmission shaft spider and the telescopic sliding key.
