FIELD: machine tool manufacture, namely teeth milling machine tools for cutting worm gears by tangential feed method. SUBSTANCE: in circuit for dividing, in differential and tangential feed circuits there are hydraulic motors kinematically joined with drive units of blank and tool. Each step hydraulic motor is controlled by means of separate hydraulic pulse generator providing necessary gear ratio of hydraulic circuits. EFFECT: simplified design of machine tool, increased accuracy due to reduced length of kinematic circuits due to removal of several mechanical links, lowered metal consumption. 1 dwg
