DEFINITION

Classification: 125/11.01

Grinding-wheel dressing:

(under subclass 10) Subject matter in which the wheel is sharpened by cutting away its glazed or loaded grinding surface, thereby exposing sharp new cutting grains to the work.

(1) Note. For ease of cutting and proper chip removal, voids are provided in the grinding wheel. As cutting proceeds, some chips become firmly lodged in the voids. This reduces grain clearance and cutting efficiency. This

condition is called "loading". [figure]
