A grinding wheel is designated coarse, medium, or fine according to the size of the individual abrasive grains making up the wheel. BONDING MATERIAL Bond The abrasive particles in a grinding wheel are held in place by the bonding agent. The percentage of bond in the wheel determines, to a great extent, the "hardness" or "grade" of the wheel.

They serve as the foundation for mounting the working die components. These parts must be machined—milled or ground—so that they are parallel and flat within a critical tolerance. Although grinding is the most popular, a milled surface now can be obtained that is as accurate as a ground surface. Most die shoes are made from steel.
