FIELD: process engineering.
SUBSTANCE: invention relates to processing of super hard materials, e.g. hard alloys, borazon, diamond, and may be used in diamond processing industry. Grinding is performed by grinding wheel fitted on machine tool spindle, intended for diamond grinding and furnished with diamond heads. Spindle rpm is varied in stepless manner to allow grinding wheel circumferential speed of 120-280 m/s. Billet is fed to grinding zone at 3-9 m/min along machine tool table feed direction and laterally in lateral machine tool table feed making 0.01-0.06 mm/double stroke.
EFFECT: higher processing efficiency.
