METHOD OF ABRASIVE WORKING Russian patent published in 2000 - IPC

FIELD: mechanical engineering. SUBSTANCE: method is intended for abrasive working of machine part surface. Part is rotated and forward motion in direction of tool is imparted to it. Abrasive is placed in production lubricating medium. During initial stage, working is accompanied by intensive removal of material with the aid of rigidly secured abrasive. To enhance mobility of abrasive grains, ultrasonic oscillations are superposed on production lubricating medium. Its viscosity is reduced, grain attachment degree is decreased, and ability of production lubricating medium to penetrate into contact zones is improved. EFFECT: improved quality of working. 1 dwg, 1 ex
