Selection of abrasive wheels

Corundum has good machinability and self-sharpening, suitable for grinding martensite and martensite ferritic stainless steel; monocrystalline corundum high toughness and hardness than corundum, suitable Mounted flap wheel  for grinding austenite and austenite and ferrite stainless steel; microcrystalline corundum good self-sharpening, easy to get sharp micro blade, high strength, good toughness, suitable for grinding stainless steel, and reduce galling, burns and reduce the grinding surface roughness values. Stainless steel inner hole grinding, grinding wheel diameter is abrasive paper sheet  small, and every single abrasive cutting the number of times to participate more easily blunt, microcrystalline corundum or single crystal corundum is better. Corundum grinding wheel selection was also very effective, not only high grinding efficiency, but also easy to burn the workpiece. Austenitic stainless steel grinding off, in order to solve the serious wheel adhesion  non woven abrasive problems, may also brittle and sharp silicon carbide grinding wheel or diamond wheel to improve grinding efficiency. When the grinding hardness greater than 275HBW martensitic stainless steel should be used cubic boron nitride (CBN) grinding wheel.Abrasive particle size, surface roughness on the stainless steel has a direct impact. Usually by grinding granular, make the surface roughness after grinding is smaller. However, due to the toughness of stainless steel, the use of a fine-grained grinding wheel, grinding wheel debris blockage of the loss of adhesion easy cutting ability, and easy to make the surface roughening, and thus should be used in coarse-grained grinding wheel.
