EDM (EDG) We have both an Electrical Discharge Manufacturing department and an Electrical Discharge Grinding department that both specialize in removal of material using electrical discharge. The EDM department specializes in manufacturing fixtures to exacting specifications.

EDG - Electric Discharge Grinding. In the present work conditions, the processes like conventional diamond grinding, electric discharge machining (EDM), and electric discharge grinding (EDG) are compared on the basis of material removal rate (MRR) and surface finish (Ra). EDG is the hybrid process of EDM and grinding and hence utilizes the benefits of both processes to give better MRR and

Abstract – Electrical Discharge Grinding (EDG) and conventional abrasive grinding are two different methods to mac hine Polycrystalline Diamond (PCD) w ith different removal mechanisms. This paper

The main object of the present work was to develop an electrical discharge machining and grinding (EDMG) methodology to remove the re-solidified layer through the grinding induced by a metal matrix composite electrode prior to the re-solidified layer solidification. Electron donating groups (EDG) with lone pairs (e.g.-OMe,NH 2) on the atoms

ness, electrical discharge grinding (EDG), a variation of electrical discharge machining, is often adopted to manufacture PCD tools to reduce manufacturing time. This paper investigates the quality of PCD inserts manufactured by two different EDG eroding methods: “2-step machining” and “3-step machining”. Surface roughness and residual

Electric discharge diamond grinding (EDDG) is the combination of EDM and fine grinding process where in grinding wheel possess metallic bonding between abrasive particles. Now-a-days other than diamond abrasives also using. So, this process become electro-discharge abrasive grinding (EDAG).

One such combination is wire electrical discharge grinding (WEDG), which is commonly used for micro-machining of fine and hard rods. WEDG employs a single wire guide to confine the wire tension within the discharge area between the rod and the front edge of the wire and also to minimize the wire vibration.

Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges (sparks). Material is removed from the work piece by a series of rapidly recurring current discharges between two electrodes, separated by a dielectric liquid

Abrasive Electrical Discharge Grinding (AEDG) . Introducing mechanical effects into EDG process leads to increase in metal removal rate. For example, in the case of Al-SiC composite, removal rate of the AEDG process (t e = 10 m s, and n = 500 rpm) is about 5 times greater than that of EDM process, and about twice of EDG process.

In this paper, in view of low grinding efficiency and poor ground surface quality of sapphire glass, the coarse diamond grinding wheel dressed by dry impulse electrical discharge was proposed to perform efficient and precise grinding machining of sapphire glass. The dry electrical discharge dressing technology was employed to obtain high grain protrusion and sharp micro-grain cutting edges

EDG use the same principle as EDM in removing a material from workpiece, through the erosive action by control the

2.1.3 Electrical discharge grinding(EDG) In the process of EDM, the characteristics of the pulse are very important, especially in the processing of PCD materials. PCD has a certain conductivity, good thermal conductivity, and high melting point, so it is very difficult to process polycrystalline diamond by traditional EDM.

Electrical discharge grinding (EDG) and conventional abrasive grinding are two different methods to machine polycrystalline diamond (PCD) with different removal mechanisms. This paper discussed the quality issues of PCD tools produced by the two processes. Although remarkably similar surface roughness and tool sharpness were obtained in both processes, it was found

The wire electrical discharge grinding is similar to EDT with respect to the kinematics, since it is only the workpiece electrode, which rotates. The translatory wire feed speed can be neglected due to its small values, since it has no additional flow effects.

Electrical discharge grinding is part of the most widely used methods to machine polycrystalline cubic boron nitride cutting tool. Polycrystalline cubic boron nitride compact samples processed in domestic with different grain size are the research object.
