The device (1) has a switchable electric servo motor (11) with a stator (12) supported at a machine bed (20). A rotor (13) of the motor is connected with a connecting rod (6) by a two stage transmission (41) and a movement converter (21) formed as a threaded roller spindle. Stages of the transmission are directly coupled with each other, where transmission ratios of the stages are reciprocal to each other. A machine spindle (5) of a machine tool (2) is in drive connection with the stages such that rotary movements of the spindle are inefficient in one stage that is attached to the motor. |
