METHOD OF CENTRELESS SUPERFINISHING OF ROUND SURFACES Russian patent published in 2003 - IPC

FIELD: machine tool industry. SUBSTANCE: invention can be at centreless grinding of surfaces of rotation. According to proposed method abrasive stick acts onto round surface of workpiece placed between two rotating transporting rolls. The latter are installed to provided asymmetry of angles of contact between abrasive stick and rolls with workpiece. Mathematical relationships between angles of contact, sized of rolls and workpiece are given in description of invention. Basing of said relationships adjusting coordinates of tool setting are found. EFFECT: improved quality of machining, reduced labour input at adjusting the equipment. 3 cl, 4 dwg
