TOOLS FOR GRINDING, BUFFING OR SHARPENING

**Definition:** This place covers:

**Limiting references (this place does not cover):** - Abrading-bodies specially designed for tumbling apparatus, e.g. abrading-balls -> B24B31/14 - Honing tools -> B24B33/08 - Lapping tools -> B24B37/11

**Glossary:** - Grinding: means machining by fixed abrasive particles in its most general sense and covers "corrective" operations, such as correction of dimension, e.g. diameter, or shape, e.g. roundness. It is characterised by a comparatively high material removal rate. - Polishing: means mechanically finishing the surface of a work so as to improve, e.g. smoothen, its surface, without substantial change of dimension or shape of the work as would occur in grinding. - Abrading: is used in its most general sense to mean mechanically removing material by a multitude of fixed or loose particles that are forced into the surface of the work so that each particle cuts away small chips of material. - Cutting: is used in the sense that an abrasive grain functions as a microscopic single-point cutting edge and shears a chip, analogous to what is conventionally called a "cut" chip.
