ELID (ELectrolytic In-Process Dressing) Grinding

The experiment of Concave spherical ELID grinding of generating method for carbide is conducted. Because dressing electrode can’t be installed in limited space due to the small space of concave spherical surfaces and carbide material has good conductivity, the workpiece material was used as dressing electrode in the ELID grinding experiment.

Electrolytic In-Process Dressing SpringerLink

Electrolytic In-Process Dressing (ELID-) grinding is a method for grinding hard and difficult to machine materials, such as ceramics in mirror surface quality. This is possible due to the chip absorbing ability of the generated oxide layer during electrolysis and the self-controlled sharpening process that results from a combination of

Efficient dressing of the wheel in ELID grinding by

Electrolytic in-process dressing (ELID) grinding is a new method for achieving ultraprecision surface on hard and brittle materials. In ELID grinding, pulsed direct current voltage is applied on the metal-bonded diamond wheels to ensure constant protrusion of sharp cutting grits throughout the grinding cycle. The peak dressing voltage is kept constant irrespective of the wheel sharpness in
