REGELUNG DES ANPRESSDRUCKS IN EINER WERKZEUGMASCHINE

摘要

The work-piece can be a slab of natural stone to be processed in order to serve as a headstone in a cemetery. The polishing or grinding tool (2) is moved by an electric drive (3) connected to a feeding unit (4, 5, 6) controlled by a computer (7, 8). The pressure of the tool (2) acting on the work-piece is normally reduced by wear and tear. In the new arrangement the pressure is determined by the power used for the rotation of the tool (2) and the position of the tool (2) automatically adjusted accordingly if required.
