RESIN BOND GRINDING WHEEL SUITABLE FOR GRINDING PROCESSING OF HARD MATERIAL SUCH AS NITRIDE-ADDED CERMET

摘要

PROBLEM TO BE SOLVED: To provide a grinding wheel capable of machining a nitride-added cermet and cemented carbide with a high grinding ratio.;SOLUTION: A diamond resin bond grinding wheel is configured such that mixed abrasive grains are used which contain a main component of abrasive powder composed of two kinds of diamond and DLC, and in which a ratio containing the diamond is 25% to 45% (55% to 75% in DLC ratio), and a grinding condition is set by which grinding heat produced during grinding does not become excessive, so that DLC to be preferentially lost is optimized to efficiently expose diamond abrasive grains of a sharp cutting edge.;COPYRIGHT: (C)2013,JPO&INPIT
