Document Type and Number:
Japanese Patent JPS62177301
Kind Code:
A
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.
