DRESSING OR CONDITIONING OF ABRADING SURFACES

FEEDING OF GRINDING, POLISHING, OR LAPPING AGENTS

In this subclass, the following term is used with the meaning indicated:

"polishing" means the smoothing of a surface, i.e. a surface improvement but no improvement of the dimensional accuracy as would occur in a "grinding" operation.

Attention is drawn to Notes (1) and (2) following the title of subclass B23F.

In groups B24B1/00 - B24B27/00, in connection with glass the terms "grinding " and "polishing" are treated as being equivalent.

In this subclass non-limiting references (in the sense of paragraph 39 of the Guide to the IPC) may still be displayed in the scheme.
