The additives are (surfactant and graphite powders) added in to EDM oil disturbs the adherence of carbon nuclides attached to the surface of the electrode and slightly reduced the tool wear [17]. Without additives added in the EDM oil increase in the TWR is due to production of ions during ionization in EDM oil when additives are added.

Effect of electrical pulse parameters on the machining performance in EDM

Graphite Products Worldwide

Copper, graphite, copper-tungsten, silver-tungsten, copper graphite and brass are used as a tool material (electrode) in EDM. They all have good wear characteristics, better conductivity, and better sparking conditions for machining. Tungsten resists wear better

Which one is better in EDM, copper electrode or

The graphite material has a lower density than copper, and the same volume of graphite electrode weighs only 1/5 of the copper electrode. It can be seen that the larger volume of the electrode is very suitable for the use of graphite material, which greatly reduces the load on the main shaft of the EDM
