There are many types of Graphite Electrodes, such as high-power graphite electrodes, ultra-high-power graphite electrodes, ordinary graphite electrodes, etc., but everyone only understands the types and uses of graphite electrodes, but they do not know much about the processing forms of graphite electrodes. In fact, there are three types of processing of graphite electrodes, namely, pressure vibration method, numerical control automatic forming method, and mechanical processing method. The three graphite electrode processing forms will be briefly explained by Graphite Electrodes Manufacturer below.
1. Pressurized vibration method requires a special machine tool, and the electrode master is opposite in shape to the electrode. The graphite material and the forming tool are placed opposite each other during processing, leaving a certain gap. A machining fluid mixed with water and abrasive is injected into it. The graphite and the forming tool are ultrasonically vibrated while passing through the working fluid. Under the action of abrasive impact, 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. The machine tool works with sealed and water curtains. Suitable for EDM forming for mass production.
2. CNC automatic forming method requires a special graphite electrode forming machine, which adopts numerical control mode and has automatic tool changing device, which can accommodate multiple tools. In order to improve the processing environment, the graphite electrode is surrounded by a water curtain to prevent the graphite dust from being scattered. Alternatively, the wet processing method can be used to prevent the tool from being worn and the graphite dust from scattering by the water-soluble cutting fluid. The machine tool has a high-performance filter device, which can separate the cutting fluid and graphite chips, and can ensure continuous processing for a long time. It is an ideal special equipment for graphite electrode processing and is suitable for electrode processing of molds.
3. Mechanical processing methods, the main methods used by general mold production units.
No matter which method is used to process the graphite electrode, a graphite material is required. Graphite materials can be processed by turning, milling, drilling and grinding. In addition, graphite materials are prone to fly ash during machining, which adversely affects processing equipment and operators.
