PURPOSE:To simplify a correcting device by setting a measuring means of run-out quantity at a correcting point and pressing means giving corrective bending deformation at the correcting point, and repeating the corrective bending which corresponds to the run-out quality. CONSTITUTION:A work 1 having parts of different diameters is supported by respective centers 2 and 3 of supporting tables 10 and 11 and is drived by a motor 4 rotatively. Run-out quantities from every measuring point of electric micrometers 12-14 are subjected to data processing. A ram 21 is actuated to give receiving parts parts 6, 7, or others a corrective deformation corresponding to the run-out quantity and the receiving parts 6, 7, or others are moved up at the maximum run-out position of the work 1. The run-out quantity after the 1st pressing is measured and the correction is repeated as necessary. A correcting device is simplified greatly because of only giving a corrective deformation corresponding to the run-out quantity of the receiving parts.
