Cutting tool production costs.
The manufacture and resharpening of indexable ceramic inserts for milling and drilling could get a boost from electro discharge dressing (ECDD), according to Hans Tonshoff; Institute of Production Engineering, Hannover, Germany Without ECDD, low material removal rates and frequent dressing of a fine grained diamond grinding wheel are needed to achieve quality edges on these inserts, which are typically made of ceramics such as aluminum oxide. ECDD, which removes wheel bond by sparks, reduces wheel loss from both dressing and grinding compared with traditional methods that use a corundum dressing stick. With ECDD applied as a continuous, in-process method, fine grained wheels can now match the material removal rates of coarse grained grinding wheels, but with greatly improved part quality.
