The principle of laser dressing superabrasive (diamond and CBN) grinding wheels is introduced, experiments on dressing metal and resin bonded superabrasive wheels by means of Nd:YAG laser are carried out.The surface topography of the wheels dressed by laser is observed by a scanning electronic microscope, the mechanism of removing bond materials is analyzed and the grinding properties of wheel dressed by laser are tested. The results show that on the surface of laser dressed superabrasive wheels, greater gr...
