The wheel grade affects all the considerations of grinding. This includes wheel speed, coolant flow, feed rates, and grinding depth. Grain Spacing This depends on the spacing of the structure. It determines the ratio of the bond and the abrasive to the air space. A less dense wheel will cut and a large cut with creating an effect on the surface.

The strength of a bond is designated in the grade of the grinding wheel. The bond is said to have a hard grade if the spans between each abrasive grain are very strong and retain the grains well against the grinding forces tending to pry them loose. A wheel is said to have a soft grade if only a small force is needed to release the grains.

3) Grade Generally, harder grade (grade L-Q) wheels are used because of the grinding condition and other constraints (such as operating speed, wheel shape and tools used). 4) Structure Wheels of comparatively dense, high in grain ratio (structure No.8 and lower numbers) are usually used. 5) Bond Vitrified (V) bonded wheels are most commonly used.

The grade is the factor which has the greatest influence on the cutting sharpness of a grinding wheel; thus, the selection of grade must be done deliberatively. As a general rule, hard material requires a low grade wheel and soft material is best ground by a high grade wheel. The common trend of grade selection is as shown in Table above.

Grade or hardness indicates the strength, with which the bonding material holds the abrasive grains in the grinding wheel. The easier a grain is torn out of the bond, softer the wheel and vice versa. The degree of hardness is specified by use of letters of the alphabet. Different grades of grinding wheels are shown in Table 3.

Grade: The term "grade" as applied to a grinding wheel refers to the tenacity or hardness with which the bond holds the cutting points or abrasive grains in place. It does not refer to the hardness of the abrasive grain. The grade shall be indicated in all bonds and processes by a letter of the English alphabet.

Grinding Wheel: Cutting Wheel: The grinding wheel has good strength which avoids cutting improper shape and size. The normal cutting tool doesn't have abrasive. So it will not provide better finishing accuracy as grinding wheel provides. The chances of wear and tear are high in cutting wheel : A grinding wheel having low chances of wear and tear.
