PROCEDIMENTO E DISPOSITIVO PER DETERMINARE IL MOVIMENTO TRASVERSALE DELLA SLITTA PORTAMOLA DI UNA RETTIFICATRICE PER SUPERFICI PIANE

In this method and device, control pulses are transmitted during the rotary movement of a threaded spindle (8), which is provided for the transverse forward movement of the grinding-disc pick-up slide. The control pulses are fed to a counter (19) of a comparison unit (20) in which the value of the counter (19) (actual value) is compared with a predetermined value of a preselector device (21) (desired value), which predetermined value corresponds to the transverse forward movement of the grinding-disc pick-up slide, and signals are transmitted from this comparison unit (20) to a control unit (23), to which signals (24) can also be fed at the same time for indicating the end position of the work table in the longitudinal direction, and regulating signals are transmitted from this control unit (23) to a servo-motor (10) for the controlled actuation of the threaded spindle (8).
