Difference Between Copper Electrode and Graphite Electrode
Copper Electrode Graphite Electrode; Copper electrode comes under the category of metallic EDM electrode. Graphite being a non-metallic material, graphite electrode is classified as non-metallic electrode. Being a ductile metal, it can be fabricated easily. Sharp corner and edges can also be provided without much problem.
The difference between graphite electrode and copper electrode
2: graphite electrode is easy to process, and the processing speed is much faster than the copper electrode. For example, the milling process of graphite, the processing speed of 2 to 3 times faster than other metal processing and no need for additional manual processing, and the copper electrode is required manpower grinding.
5 Reasons to Consider Copper Impregnated Graphite Electrodes
Apr 11, 2017· Copper impregnated graphite is chosen for electrodes when qualities from both materials are warranted. A shop looking for a material that results in better surface finish and better flushing, while able to hold finer detail or provide a higher metal removal rate may find a copper-impregnated graphite to be a good choice.
Graphite or Copper? Part 1 : MoldMaking Technology
Aug 01, 2014· For copper electrodes to release electrons in the gap, the temperature must be high enough for these electrons to absorb sufficient energy.1 As a result, these high temperatures tend to burn some of the copper electrode away. In order to generate this heat, the on times for copper electrodes are generally much higher than for graphite electrodes.
