What are the processing procedures for graphite electrodes?
1) Graphite oil immersion. Before machining, graphite materials should be immersed in engine oil for dozens of hours to allow the oil to penetrate the graphite material, so that the dust will not fly during machining and a smoother surface can be obtained.
2) Paint and line drawing. After the electrode is roughly machined on the surface, a thin layer of white paint is sprayed on the line drawing surface before line drawing. This way, the lines are clear and easy to machine.
3) Machine machining.
