Abstract The main reason affecting the honing quality and machining efficiency is that the rock of honing first is jammed and the grain is wore to obtuse easily. So adopting an Effectual truing method, maintaining the required sharpness of abrasive grits for honing first during grinding is one of the key technologies to realize the grinding of hard and brittle material . In this paper, we introduce the skill craft of ELID. studies on combining electrical discharge and mechanical truing for honing first and ELID grinding. Introducing the characteristic of the honing in the sometime, It is a kind of solid knot that honing whet is to process the method when a pressure enter to slice, not only can it cut off bigger process but the amount of remaining and size accuracy and shape accuracy of the ability valid exaltation work piece, lower rough degree of a surface of work. The honing whets to mainly process inside the bore, can also process the outside circle, flat surface, surface of sphere under the condition of certain. The honing whets are to adopt the conjunction with principal axis generally, matching the light processed float. Firstly, based on analyzing and summarizing the theory of ELID, the cathode And anode brush of the ELID system are designed and developed. By studying on the electrolytic Characteristics and the oxides film growing characteristics of the metallic bonded honing first, the ELID grinding fluid is developed. Key Words: Electrolytic In-process dressing, honing first, honing, rock
