FIELD: machine tool manufacture; making helical and spur gear wheels. SUBSTANCE: machine includes tool unit, blank unit, hydraulic stepping motors, hydraulic pulse generators and mechanism for conversion of uniform rotation of hydraulic stepping motor mounted in chain of uniform linear motion of blank to non-uniform translational motion of table with blank engageable with cam connected with hydraulic stepping motor. Above-mentioned mechanism is made in form of motion screw kinematically linked with gear rack engageable with cam. EFFECT: simplified construction of internal kinematic chains; reduced number of components of chain and stepping hydraulic motors. dwg
