ELID Fine Grinding of SiC Bearing Rollers

Abstract:

Electrolytic in-process dressing (ELID) grinding is drawing more and more attention by the researchers for its smart method of in-process dressing of the grinding wheel. Many researches place emphasis on study of in-processing dressing and oxide layer. In this study, the effects of three grinding factors, including wheel speed, load applied on workpiece and eccentricity of three parts in one holder, on surface roughness (Ra) and material removal rate (MRR) were investigated in a single-side ELID grinding experiment. Each factor has three levels. The experimental results show that each factor has different influence: 1. Applied load is the main factor which significantly affects the Ra and MRR; 2. the speed of grinding wheel doesn’t show much influence; 3. eccentricity has a great influence on roughness but not on material removal rate.
