ABSTRACT:
A truing apparatus includes a truing tool supported on a tool support movable radially and axially of a grinding wheel having a rounded corner and drivable by a feed drive unit coupled to the tool support to move along a predetermined path for truing the rounded corner of the grinding wheel. At least one contact member for contacting outer peripheral and end surfaces of the grinding wheel is mounted on the tool support, and a sensor is also mounted on the tool support for detecting a contact between the contact member and the grinding wheel. A feed control system controls the feed drive unit for moving the truing tool along the predetermined path. The feed control system controls the feed drive unit so that the contact member will move radially and axially of the grinding wheel until the sensor is actuated immediately after one truing process and immediately before a next truing process. A grinding wheel position detector detects radial and axial positions of the grinding wheel when the sensor is actuated immediately after the one truing process and immediately before the next truing process. A correcting unit corrects the predetermined path along which the truing tool is to move in the next truing process based on the positions of the grinding wheel detected by the grinding wheel position detector immediately after the one truing process and immediately before the next truing process.
