1) Graphite oil immersion. Before the mechanical processing, the graphite material should be immersed in the oil for several tens of hours to allow the oil to penetrate into the graphite material, so that the ash powder does not fly during machining and a smoother surface can be obtained.
2) Paint scribe line. After roughing the surface of the High Power Graphite Electrodes, a thin layer of white lacquer is applied to the surface of the scribe line and then scribed, so that the line is clear and easy to machine.
3) Perform machining.
