摘要

Drive mechanism for indexing the spindle drum (10) of a multi-spindle automatic lathe to the next position, which drive mechanism has a hydraulic motor (14) with secondary control means (21), the sequence of movement of which is controlled according to predetermined desired values via an electronic control circuit as a function of the respective angular position of the spindle drum (10) in order to obtain the fastest possible, accurate and smooth indexing of the spindle drum to the next position. <IMAGE>
