Abstract
Improved rigid grinding wheels are described which have a rigid organic matrix binding particulate diamond or cubin boron nitride abrasive uniformly dispersed therein between a plurality of spaced-apart apertures extending inwardly from the operative grinding surface of the matrix. The cross-sectional open area of the apertures in the matrix reduces the operative solid grinding surface and provides swarf relief while also increasing the effective concentration of a given amount of abrasive in the griding surface, this increasing the efficiency of the grinding wheel while reducing the cost of the wheel and power consumption in use.
