METHOD OF GRINDING SURFACES OF WORKPIECES Russian patent published in 2001 - IPC

FIELD: mechanical engineering. SUBSTANCE: workpiece is ground with a flexible tool. The working surface of the tool is covered with an abrasive and not working surface is rigid. The chamber of the tool is filled up with a cutting fluid in a solid state. Ultrasonic vibrations are imparted to the workpiece in direction perpendicular to the axis of rotation of the tool intensifying contact between the tool and the workpiece and making the cutting fluid to be in a liquid state and supplying it to the cutting zone through passages provided in the working surface of the tool. EFFECT: improved conditions of micro-cutting and contact between interacting surfaces, enhanced quality of grinding. 2 cl, 1 dwg
