Abstract

PURPOSE: To coincide antomatically the center of a grinding wheel with that of a work by detecting both sides of the work with a pair of detectors, detecting the offset of work center with the center of the grinding wheel, and controlling the movement of the tool head so as to diminish the offset.
CONSTITUTION: When a tool (a grinding wheel) 3 moves in the Z-Z' direction approaching the center of a work pin 5, a switch SW closes and actuates a solenoid 17 to attract iron pieces 15 and 16. This attraction turns contactors 13 and 14 to the positions shown by chain lines, and their tips touch both sides of the work pin 5. In accordance with this turning motion, the working pieces 20a and 21a of detectors 20 and 21 move and output detecting signals Ea and Eb respectively and input to a servo motor 10 a signal Ec with the polarity and magnitude corresponding to the direction and the dimension of the offset of the tool 3 to the center of the work pin 5. By so doing, said motor 10 moves the tool head 4 to the direction of Z or Z' to align the tool 3 and the center of the work pin 5 following the signal Ec.
