RESIN BOND GRINDING WHEEL SUITABLE FOR GRINDING OF HARD MATERIAL SUCH AS NITROGEN-ADDED CERMET AND GRINDING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a grinding wheel and a grinding method for machining nitrogen-added cermet and cemented carbide at high grinding ratio.;SOLUTION: Grinding is executed by using a resin bond grinding wheel using abrasive grains of which the ratio of including diamond abrasive grains is 25-45% (55-75% in DLC ratio), and/or the X-ray diffraction intensity of diamond {311} crystal face of abrasive grain powder is 4,900-6,250 count under the condition of 70% or less of abrasive grains smoothing ratio.;COPYRIGHT: (C)2010,JPO&INPIT
