Electrolytic In-Process Dressing (ELID) grinding using a super-abrasive wheel has opened up the gateway for ductile machining of hard and brittle materials to achieve nanometric surface finish. ELID grinding uses anodic dissolution of a metal-bonded grinding wheel to ensure constant protrusion of the sharp grits to realize smooth and stable grinding operation throughout.

In electrolytic in-process dressing (ELID), a metal-bonded grinding wheel is dressed as a result of anodic dissolution. In this paper we describe experiments to evaluate the potential for ELID on bronze wheels in fixed-load grinding applications.
