ELID Grinding and Polishing - ScienceDirect. ELID grinding was first proposed by the Japanese researcher Hitoshi Ohmori back in 1990 . The most important feature is that no special machine is required. Power sources from conventional electrodischarge or electrochemical machines can be used for ELID, as well as ordinary grinding machines.
To apply electrolytic in-process dressing (ELID) /1/ to the machining of small internal diameters which are difficult to fit with electrodes, and electrolytic interval dressing (ELID II) grinding method described in Figure (1)/2/ which performs intermittent dressing was developed. This method has helped realize the internal mirror-surface ...

There is here disclosed a nozzle type ELID grinding apparatus comprising a conductive grindstone 12 having a contact surface with a workpiece 1; and an ion supply nozzle 16 that supplies an electrolytic medium 2 containing hydroxyl ions (OH − ) onto a surface of the conductive grindstone, the workpiece being ground while the surface of the grindstone is dressed by electrolysis or chemical ...
Abstract. In this study, electrolytic in-process dressing (ELID) grinding experiments were conducted on SiCp/Al composites, and the effects of grinding depth and feed speed of work table on grinding force, surface roughness, and surface morphology were investigated.
A significant improvement in the strength of the Si 3 N 4 specimens was noted when finish ELID grinding was performed. This was the result of ductile regime grinding using the application of finish ELID grinding. Another method to improve the flexural strength of silicon nitride specimens will also be addressed in this paper.

The groove profile of ball-bearing raceway is of vital importance to ensure the bearing transmission accuracy. It is an attempt to apply electrolytic in-process dressing (ELID) groove grinding for the ball-bearing raceway finishing process. The wear rate of the grinding wheel is directly related to the profile accuracy of the bearing raceway.
