processing method. In order to let everyone know more about the graphite electrode, the processing method for the graphite electrode will be explained.
    1. The pressure oscillation method requires a special machine tool, and the electrode master mold has the opposite shape to the electrode. Graphite data and forming objects are placed relative to each other during processing, leaving a certain gap. A machining fluid mixed with water and abrasive is injected into it. Together with the processing fluid, the graphite and the shaped object are subjected to ultrasonic oscillation. Under the effect of abrasive impact, the graphite is slightly stripped to the desired shape. The abrasive is SiC, B4C or diamond, and the thicker the abrasive, the faster the processing speed. Sealing and water curtains are used for machine tool work. Suitable for EDM forming for batch production.
    2, CNC active forming method requires a special graphite electrode forming machine, which uses the numerical control method, has the tool active interchange equipment, can accommodate multiple tools. In order to improve the processing environment, the graphite electrode is surrounded by water curtains to avoid the scattering of graphite dust. Others can also use the wet processing method to prevent the tool from being worn and the graphite dust from scattering by the water-soluble cutting fluid. The machine tool has high-performance filter equipment, which can separate the cutting fluid and graphite chips, ensuring long-term continuous processing. It is a special equipment for graphite electrode processing and is suitable for electrode processing of molds.

    3. The mechanical processing method is the method selected by the domestic general mold production unit. Graphite electrodes can be machined by turning, milling, drilling and grinding.
