ELID-grinding is well known as an effective mirror surface grinding method, and is expected to be more efficient by addition of new function. Fine bubble is one of its candidates. We attempted to mix air fine bubble for ELID-grinding fluid, and to characterize its effects on interaction between the grinding wheel and the workpiece. Then, the effects of CO2 fine bubble on grinding ratio and wheel wear have also been evaluated. As a result, fine bubble can avoid clogging of grinding wheel and keep the grinding ability together with ELID, and can improve grinding ratio and wheel wear.
