Silicon carbide (green silicon carbide or carburundum) is an invaluable abrasive material with only diamond, cubic boron nitride and cemented carbide having comparable hardness levels. Cutting through soft materials such as glass, ceramics and nonferrous metals with ease, aluminum oxide abrasives are notoriously brittle and short-lived. Abrasive Grit An abrasive grit of a grinding wheel is what does the cutting, with its size depending on what material needs grinding. Finer grits provide more precision or fine work, while coarser ones are designed for heavy stock removal or rough grinding. A grinding wheel’s abrasive grit is classified by its hardness, which is determined by the strength of the bond that holds …
