Classification Context

Section:: PERFORMING OPERATIONS; TRANSPORTING
Class:: GRINDING; POLISHING
Subclass:: TOOLS FOR GRINDING, BUFFING OR SHARPENING

Description

B24D covers abrasive tools and grinding wheels designed for material removal, surface finishing, and edge preparation operations. This subclass encompasses rotating wheels, stones, and mounted abrasives used in grinding machines, as well as honing and sharpening tools for cutlery and industrial implements. Included are various abrasive compositions, grain types, and bonding materials that affect tool performance and durability. Related grinding machine designs and their operational mechanisms are classified separately under B24B.

Scope Notes

Glossary: grinding 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 Polishing means abrading 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. | Limiting references: Abrading-bodies specially designed for tumbling apparatus, e.g. abrading-balls Honing tools Lapping tools | Application references: Floor surfacing or polishing machines with driven tools Grinding discs or grinding worms specially adapted for use in machines for manufacturing gear teeth Tools specially designed, e.g. bowl-like, for grinding or polishing optical surfaces on lenses or surfaces of similar shape on other work
