Electrolytic in-process dressing (ELID) grinding is a new technique for achieving a nanoscale surface finish on hard and brittle materials such as optical glass and ceramics. This process applies an electrochemical dressing on the metal-bonded diamond wheels to ensure constant protrusion of sharp cutting grits throughout the grinding cycle.

less in-process dressing (ELID-III). During electrolytic dressing, the base material is oxi-dized and the wheel surface contains resin and diamond grits. Theoretically the metal-bond is removed by electrolysis, but the experimental results showed that the grinding wheel sur-face contains cavities, which are caused by electric discharge.

During grinding, the insulating layer and abrasive grains are scraped off and removed, resulting in a decrease in the wheel's electrical resistance. As a result, the electrical current through the wheel and the electrode increases and electrolysis restarts. This dressing cycle repeats during the ELID grinding process.
