FIELD: machine tool manufacture. SUBSTANCE: rolling out circuit of gear planer includes hydraulic step motors kinematically connected through worm gearings and lengthwise-feed leading screw with round table, with integrating mechanism in the form of differential with cone gear wheels and with rectangular table. Each step hydraulic motor is controlled by means of separate hydraulic pulse generator. EFFECT: simplified structure, enhanced accuracy due to lowered duration of kinematic circuit from which several gearings are removed, lowered metal consumption. 1 dwg
