Features: Wheels for CNC machining cutting tools refers to Resin bond diamond/CBN grinding wheels and Vitrified bond diamond/CBN grinding wheel for drill and endmill etc. This kind of grinding wheel has high efficient, better wear resistance, enhancing high stock removal rate in fluting, gashing, thinning, high profile retention and good surface roughness, longer wheel dressing interval, sustain cutting toolsâ?? geometric stability. Application: CNC machining cutting tools used diamond grinding wheels is applied to grind carbide. CNC machining cutting tools used CBN grinding wheels is applied to grind HSS (high speed steel).
