ORDERED MICRO SLOT STRUCTURE PCD GRINDING WHEEL CAPABLE OF PERFORMING POSITIVE RAKE ANGLE PROCESSING AND MANUFACTURING METHOD THEREFOR

摘要

An ordered micro slot structure PCD grinding wheel capable of performing positive rake angle processing, comprising a wheel hub (1). A PCD film (2) is deposited at the outer peripheral surface of the wheel hub (1); a plurality of micro slots (10) with a high depth-to-width ratio, which has axial length equal to the thickness of the grinding wheel, peripheral width being only dozens of microns, and depth being hundreds of microns, is processed in the outer peripheral surface of the PCD film (2), and a plurality of micro grinding units (9) having positive rake angles is formed in the outer peripheral surface of the PCD film (2), the micro grinding units (9) and the micro slots (10) being orderly arranged. The ordered micro slot structure PCD grinding wheel can implement positive rake angle processing, improves grinding performance, and prolongs the service life of the grinding wheel. Further provided is a manufacturing method for the ordered micro slot structure PCD grinding wheel capable of performing positive rake angle processing.
