Effect of electro-discharge dressing on surface topography of metal-bonded CBN grinding wheel
摘要
Abstract
Performance of metal-bond CBN forming grinding wheel is excellent,and it is widely used in grinding of complex and precision workpiece.However,it is difficult to dress the metal-bond CBN forming grinding wheels.Saw-teeth shape metal-bond CBN grinding wheel was dressed by electro-discharge in surface grinder.It was observed that effective abrasive particles and effective height of abrasive particles increased after dressing by analysis of wheel's surface topography.Then the dressed CBN grinding wheel was used to grind saw-teeth in material 2T8/SK5,during which the measured angle accuracy of saw-teeth was obviously improved.Electro-discharge dressing method is suitable to dress metal-bond CBN forming grinding wheel.关键词
