GRINDING FOR TOOLMAKING

steel is alloyed with carbide-forming elements, primarily tung-sten, molybdenum and vanadium. The carbon content of the steel must also be relatively high in order to form carbides. Only boron nitride and diamond are harder than all of the carbides present in a tool steel. Diamond, however, is not minutes can also be used to make grinding cracks visible.

How to choose the grinding wheels for stainless steel ...

07/12/2018  When stainless steel grinding, the grinding force is large and the abrasive grains are easily blunt, making the grinding wheel wear. In general, when stainless steel grinding, the grinding ratio is G=6-12, while ordinary carbon steel and low alloy steel grinding, the grinding ratio is G=40-80. Therefore, the grinding ratio of stainless steel is only about 1/7 of that of ordinary steel.
