ABSTRACT:
A workpiece (1) is fixed by means of a chuck (4) and rotates with a spindle (3) in a headstock (2). A first cam (30) is fixed to the main shaft of the spindle. Its control surface guides a feeler roller (31). A rotary pulse generator (8) is actuated by the rotation of the spindle shaft. An auxiliary motor (10) is disposed on a cross-slide (12) and causes an auxiliary shaft (21) to rotate. The pulse generator produces synchronization between the spindle shaft and the auxiliary shaft. The latter bears a second cam. According to the position of the cross-slide, the exact location of teh tools (16, 17) is determined by the first cam or by the second.
