The advantages of graphite electrodes are easier processing, high removal rate of electrical discharge machining, and low graphite loss. Therefore, some group-based spark machine customers abandon copper electrodes and switch to graphite electrodes. In addition, some special-shaped electrodes cannot be made of copper, but graphite is easier to form, and copper electrodes are heavier and not suitable for processing large electrodes. These factors have caused some group-based spark machine customers to use graphite electrodes.

Graphite electrodes are easier to process, and the processing speed is significantly faster than copper electrodes. For example, the use of milling technology to process graphite, the processing speed is 2 to 3 times faster than other metal processing and does not require additional manual processing, while the copper electrode requires manual frustration. Similarly, if a high-speed graphite machining center is used to manufacture electrodes, the speed will be faster and the efficiency will be higher, and there will be no dust problems. In these processes, choosing tools with appropriate hardness and graphite can reduce tool wear and copper damage. If you compare the milling time of graphite electrodes and copper electrodes, graphite electrodes are 67% faster than copper electrodes. In general electrical discharge machining, the processing of graphite electrodes is 58% faster than copper electrodes. In this way, the processing time is greatly reduced, and the manufacturing cost is also reduced.

The design of the graphite electrode is different from that of the traditional copper electrode. Many mold factories usually have different reservations for roughing and finishing of copper electrodes, while graphite electrodes use almost the same reservations. This reduces the number of CAD/CAM and machine processing. For this reason alone, Enough to improve the accuracy of the mold type to a large extent.
