摘要
FIELD: machine tool manufacture. SUBSTANCE: machine tool includes blank unit, tool unit, tuning unit, differential mechanism; hydraulic step motors mounted in indexing and differential circuits and designed for rotating blank and cradle carrying cutting tool; hydraulic pulse generators arranged in tuning units of said hydraulic step motors and designed for providing transfer ratio of said circuits in accordance with relation of frequency values of hydraulic pulses. Said relation depends upon designed number of working slits in rotating sleeves of slide valves of hydraulic pulse generators. EFFECT: simplified kinematic circuit of machine tool providing lowered metal consumption and improved accuracy of working. 1 dwg
