ABSTRACT:
Electrical contact between a probe and a holder and/or a workpiece is detected by a detection circuit in a machine tool having a spindle located above a movable table. The probe is mounted on a chuck which is, in turn, mounted on the spindle. An arm is also mounted on the spindle. The probe, chuck and arm all form an electrically conductive assembly. A magnetic electrode or a clip electrode is mounted on the assembly, each electrode being electrically connected to the detection circuit.
