The goal of this study is to investigate the capability of electrolytic in-process dressing (ELID)-grinding for achieving high material removal rate (MRR) on hardened steels without adversely affecting the surface quality of the workpiece.
Grinding experiments with wheels of ~50μm grits on a cylindrical grinder (Studer S20) indicate that the best achievable roughness is mainly determined by the abrasive grit size and depends very little on the grinding technique (ELID versus conventional grinding), nor on the bonding type of the wheel. With higher material removal rate chattering was observed in ELID-grinding. Experiment results also showed that the grinding ratios of ELID-grinding with 50 μm cBN abrasives can be 5 to 10 times higher than that in conventional vitrified grinding with the same grit size.
