ABSTRACT:
A machine tool comprises a spindle device carrying a tool element attached to the forward end of a rotor spindle drivingly rotatable as supported by a control-type magnetic bearing device, a working force calculating unit for calculating a working force acting on the tool element upon the tool element coming into contact with a workpiece based on exciting current of a magnetic bearing of the bearing device, and a discriminating unit for discerning whether the contact of the tool element with the workpiece is normal or abnormal based on variations in the working force.
