METHOD FOR WORKING SCREWS OF GERATOR SCREW PUMPS

摘要

FIELD: machine engineering, working in lathes. SUBSTANCE: method comprises steps of rotating worked part and cutting tool and realizing rectilinear feed motion of cutting tool along axis of worked part; performing working by means of end surface and partially by lateral surface of cutting tool whose spindle axis is inclined by acute angle epsilon relative to straight line normal to part rotation axis; determining value of said angle according to formula given in description of invention; imparting to tool planetary motion matched with its rectilinear feed motion at condition of moving spindle axis around said straight line normal relative to part axis. EFFECT: enlarged manufacturing possibilities, enhanced efficiency and quality of working. 3 dwg
