Abstract

fects of different water-based grinding fluids on material removal rate, edge chipping damage and surface roughness in the abrasive machining of a micaceous glass, dental-type ceramic restorative material were investigated under simulated clinical-dental grinding conditions. Significant differences in removal rate were obtained among the fluids investigated, but only a 4 wt. % boric acid solution gave a higher removal rate than conventionally-used water without additives. Edge chipping damage was substantially lower for the 4 wt.% boric acid solution and an oil-emulsion coolant compared to other fluids tested. Surface roughness was independent of the fluid used. The results indicate that improvement can be achieved in both material removal rate and grinding damage by the appropriate choice of grinding coolant chemistry.
