Advantages of graphite electrodes

1. The increasing complexity of mold geometries and the diversification of product applications have led to higher and higher requirements for the discharge accuracy of spark machines. The advantages of the graphite electrode are that the processing is easier, the discharge processing rate is high, and the graphite loss is small. Therefore, some group-based spark machine customers give up the copper electrode and switch to the graphite electrode. In addition, some special shaped electrodes can not be made of copper, but graphite is easier to form, and the copper electrode is heavier and not suitable for processing large electrodes. These factors have caused some group-based spark machine customers to apply graphite electrodes.

2. Graphite electrode is easier to process, and the processing speed is significantly faster than the copper electrode. For example, the processing of graphite by milling process is 2 to 3 times faster than other metal processing and does not require additional manual processing, while the copper electrode requires manual grinding. Similarly, if high-speed graphite machining center graphite electrode is used.

Manufacturing electrodes will be faster, more efficient, and will not cause dust problems. In these processes, selecting the right hardness tool and graphite can reduce the tool wear loss and copper breakage. If the milling time of the graphite electrode and the copper electrode graphite electrode is specifically compared, the graphite is 67% faster than the copper electrode. In the general case of electrical discharge machining, the processing using the graphite electrode is 58% faster than the copper electrode. As a result, the processing time is greatly reduced, and the manufacturing cost is also reduced.

3. The design of graphite electrode is different from that of traditional copper electrode. Many mold shops usually have different reserves for roughing and finishing of copper electrodes, while graphite electrodes use almost the same amount of reservation, which reduces the number of CAD/CAM and machining times. For this reason alone, Sufficient to improve the accuracy of the mold cavity to a large extent.
