PROBLEM TO BE SOLVED: To provide a grinding device capable of simplifying work and capable of enhancing accuracy by dispensing with teaching work, by automatically performing a series of grinding work, without stopping the device once a work is arranged even the work is a large bearing ring or the like.SOLUTION: A bearing detecting part 30 comprises a contactor 31, and detects a position and a shape of a bearing inner ring 1 by bring the contactor 31 into contact with the bearing inner ring 1. A grinding wheel operation part 50 comprises a servomotor, and moves a grinding wheel 41 by driving the servomotor of the grinding wheel operation part 50. A coordinate system-related information group such as position-shape information based on an origin Owith the main shaft rotational center as a reference, is stored in a storage part 71 of a control part 70. The control part 70 positions the grinding wheel 41 by controlling the grinding wheel operation part 50 by integrating respective coordinate systems of the bearing inner ring 1, the grinding wheel 41 and a dress 61 on the basis of the coordinate system-related information group in the storage part 71 and driving information on the servomotor of the grinding wheel operation part 50. |
