Alloy wheel, commonly known as grinding carbide grinding wheel, grinding lathe tool grinding wheel, its material should be green silicon carbide ceramic wheel, you should use the white grinding wheel white corundum grinding wheel, and is not suitable for running-gold. Run-gold grinding wheel with optional: 46 #, 60 #, 80 #, 100 #, the hardness of the "K" or "L" green silicon carbide ceramic grinding wheel.

No grinding the ability? Refers to the grinding wheel is too hard it, if this is the case, the production of the manufacturers of the grinding wheel can be called, the lowest hardness of the grinding wheel, and to increase the proportion of the diamond, to reduce the content of the resin, so as to achieve the self-sharpening grinding wheel, if the roughness can allowed, to maximize the intensity of the grinding wheel. I only know, I hope you have some help.
