ELID grinding characteristics of Ti alloy using an electroconductive porous rubber-bonded wheel

Abstract

The authors have developed an electroconductive porous rubber-bonded wheel to enhance finishing characteristics in ELID grinding, and investigated the electrolytic dressing characteristics and grinding characteristics of this grinding wheel. In this study, we fabricated grinding wheels with #400 SiC abrasives, and ground Ti alloy by ELID lamp grinding. Experimental results showed that electrolytic dressing forms a layer with large specific wear and frictional coefficient on the grinding wheel surface. We also conducted ELID grinding experiments of Ti alloy, and the results confirmed that the grinding wheel maintains grinding performance and the ground surface has excellent tribological features.
