There are five characteristics of a cutting wheel: material hardness, grain size, wheel grade, grain spacing, and bond type. They are indicated by codes on the wheel's label. The abrasive aggregate is selected according to the hardness of the material being cut. • Aluminum oxide (A)• Silicon carbide (S)• Ceramic (C)• Diamond (D, MD, SD)• Cubic boron nitride (CBN)Grinding wheels with diamond or CBN grains are called superabrasives. Grinding wheels with aluminum oxide (corundum), silicon carbide, or ceramic grains are called conventional abrasives. From 10 (coarsest) to 600 (finest), determines the average physical size of the abrasive grains in the wheel. A larger grain will cut freely, allowing fast cutting but poor surface finish. Ultra-fine grain sizes are for precision finish work. generally grain size of grinding wheel are 10-24(coarse),30-60(medium),80-200(fine) and 220-600(very fine). From A (soft) to Z (hard), determines how tightly the bond holds the abrasive. A to H for softer structure, I to P for moderately hard structure and Q to Z for hard structure. Grade affects almost all considerations of grinding, such as wheel speed, coolant flow, maximum and minimum feed rates, and grinding depth. Spacing or structure, from 1 (densest) to 17 (least dense). Density is the ratio of bond and abra
