Cutting wheels for metal cutting, used on grinders, grinders and cutting machines.

Abrasive tools include grinding wheels, heads, segments, bars on a flexible base, elastic wheels, skins, tapes, pastes.

Of these tools, the most common is the grinding wheel. It is a body of rotation that takes different sizes and profiles in the axial section. An abrasive tool has pores (voids). The ratio between the number of bonds and between the pores determines the hardness of the abrasive material, and the ratio between the number of bonds and grains determines its structure. The hardness of the abrasive material is the property of bonds to resist the breaking of abrasive grains from its working surface.
