White corundum grinding wheel is made of industrial alumina powder as the main raw material and melted in electric arc furnace. White corundum grinding wheel is one of the most important grinding tools in grinding. White corundum grinding wheel is a porous body made by adding binder into abrasive, pressing, drying and roasting. Due to the differences of abrasives, binders and manufacturing processes, the characteristics of grinding wheels are very different, which has an important impact on grinding quality, productivity and economy. The characteristics of grinding wheel are mainly determined by abrasive, strength, binder, hardness, structure, shape and size.
Code-named (PA) chrome corundum grinding wheel is made of industrial alumina powder as the main raw material, adding a proper amount of metal oxides, and melting in an electric arc furnace. Its color is light rose red, its hardness is similar to that of white corundum, and its toughness is higher than that of white corundum grinding wheel.
