PROBLEM TO BE SOLVED: To provide a mass centering machine capable of carrying out center hole work to an asymmetric rotor.SOLUTION: A mass centering machine 1 includes a support part K27 which supports a rotor 26 whose center hole should be worked, and a control part. When the rotor 26 is an asymmetric rotor having couple imbalance U, the control part corrects a movement amount when the support part K27 is moved in order to perform attitude control of the rotor 26 whose mass center is measured as a pre-stage of center hole work, in accordance with deviation in the couple imbalance Ugenerated by rotation of the rotor 26 caused by horizontal movement of the support part K27.SELECTED DRAWING: Figure 4 |
