Background
High speed rotating machines are greatly affected by materials, and various reasons for the work piece can cause unbalanced faults to the rotor system of the machine. While a vibration failure of the rotating machine results from an unbalance of the rotor system for 70%. In general, a newly processed rotor is corrected by forward action balance, or for a rotor with large vibration, the rotor is removed, directly replaced, and the like, and is installed again and then operated, so that the purpose of reducing vibration is achieved. In order to ensure the safety of personnel and the normal operation of production, the dynamic balance correction is needed to be carried out on the large-scale wheel-shaped workpiece.
