Abstract

A grinding robot for grinding an electrically conducting workpiece. The grinding robot includes a grinding wheel, an actuation device for actuating grinding wheel, and a control system. The grinding wheel including an undulated tool receptacle which defines an axis of rotation about which the grinding wheel can rotate during grinding, and a head which is rotationally symmetrical with respect to the axis of rotation, and which contains abrasive material and has a grinding surface which is in contact with workpiece during grinding. The grinding wheel also includes a measuring and transmission unit and at least one conductor strand pair with two conductor strands which are electrically insulated from one another. The conductor strands are embedded in the rotationally symmetrical head and extend from the grinding surface of the head into the interior of the head and are electrically connected with measuring and transmission unit.
