METODO E DISPOSITIVO PER IL CONTROLLO CONTINUO DELLA SPINTA APPLICATA SUI PEZZI IN LAVORAZIONE IN UNA MACCHINA LAPPATRICE A DOPPIO PLATEAU.

摘要

A method of and an apparatus for continuously controlling the pressure applied on workpieces in a double-plate lapping machine, in which the upper plate is connected by means of a linear transducer for controlling the position thereof to a central processing unit driving a servomotor associated to a pressure measuring unit provided with a videodisplay and interconnected between the servomotor and the plate for measuring the pressure applied to the plate, and belonging to a mechanicai assembly causing the plate to axially move in both directions so as to continuously adjust the pressure on the workpieces according to data set in the central processing unit and the signals fed by the transducer and the pressure measuring unit.
