Notes:
Tungsten carbide which is a hard and brittle material was ground by cast-iron bondeddiamond wheel with ELID (Electrolytic In-Process Dressing) technique, for the purpose of gettinghigh efficiency, super-precision machining. Three kinds of cast-iron bonded diamond wheels withdifferent grain size were adopted to get different grinding efficiency and surface quality ofworkpieces. The grinding properties of cast-iron bonded grinding wheels with different grain sizeand the ground surface quality of tungsten carbide are discussed in this paper. The experiment resultsindicate that, under the same feeding amount, the grinding efficiency of the wheel with bigger grainsize is higher, and it could make the dimension accuracy of the workpiece controllable, but thewheel with smaller grain size could get better ground surface quality. The two grinding phases aredecided by the ratio between the size of abrasive grain and the thickness of the oxide layer on thegrinding wheel
