When side grinding with the Type 27 or Type 28 wheel, the work piece acts as a portion of the guard, protecting the operator in the event of a wheel breakage. Cutting off wheels are not designed for use on their side and must be used on their outer periphery only. Guards for cutting off wheels must cover a full 180° area on all sides of the wheel.

Principles of Grinding. In all forms of grinding, three different interactions occur between the abrasive and the machined material. Cutting occurs where the abrasive grain is sufficiently exposed to penetrate the workpiece material and curl a chip, and sufficient clearance exists between the grain, bond and workpiece to flush the chip with coolant or throw it away by wheel action.
