FIELD: cutting non-round gear wheels with straight and helical teeth by means of hobbing milling cutter. SUBSTANCE: machine tool is provided with hydraulic step motors arranged in circuits for indexing, for feeding tool, for non-uniform tool motion in axial direction and hydraulic pulse generators arranged in circuits for adjusting above mentioned step hydraulic motors and designed for receiving gear ratio corresponding to relation of pulse frequency values related with designed number of working slots in rotary spool sleeves of hydraulic pulse generators. EFFECT: enhanced accuracy, lowered metal consumption due to shortened length of kinematic circuits in the result of excluding set of mechanical links out of these circuits. 1 dwg
