In a machine tool with a spindle (10) capable of motion along at least three axes x, y, and z, the position of the spindle is checked by a device that operates utilizing electromagnetic signals sent out by four emitters (20), located externally of the machine tool, and picked up by a receiver (21) mounted directly to the spindle. The signals are fed into a master control unit (23) and processed by circuits (24, 25) in such a way as to produce an output that can be used to verify and if necessary correct the position of the spindle on the three axes X, Y, and Z. <IMAGE> |
