ABSTRACT:
A tool, in particular a lapping wheel, is to be positioned by a hydraulic drive cylinder and subsequently pressed against a workpiece. For this purpose a position control and a pressure or force control is provided. The weight change of the lapping disk subjected to wear is automatically detected by measuring the pressure value which is necessary to keep the weight in a state of suspension without support. The pressure value is stored and in the subsequent pressure regulating operation fed as compensating parameter to the pressure control circuit.
