PROBLEM TO BE SOLVED: To efficiently correct a rotor balance in a short period of time.SOLUTION: A balance measurement device measures the balance of a rotor in a state of rotating the rotor (S101). A first processed part of the rotor determined based on the measurement result is irradiated with a laser beam by a laser irradiation device to remove the processed part, so that balance of the rotor is corrected (S107). After removing the first processed part of the rotor, the balance of the rotor is measured again (S108). In the case where the measurement result shows that correction of balance is insufficient (S108:YES), the rotor is rotated at lower speed than rotational speed of the rotor at the time of removing the first processed part and at the same time a second processed part of the rotor determined based on the balance remeasurement result is irradiated with a laser beam by the laser irradiation device to remove the second processed part (S110).SELECTED DRAWING: Figure 2 |
