What Are The Advantages Of Graphite Electrodes?

Apr 24,2019January 10, 2019
Graphite electrode is easy to process and the processing speed is obviously faster than that of copper electrode. For example, when graphite is processed by milling process, it can be processed 2 to 3 times faster than other metals without additional manual processing, while the copper electrode needs to be ground by hand. Similarly, if the electrode is made in a high speed graphite processing center, it will be faster and more efficient without creating dust problems. In these processes, choosing the right hardness of tools and graphite can reduce tool wear and copper breakage. If the milling time of graphite electrode is compared with that of copper electrode, graphite electrode is 67% faster than that of copper electrode. In general, the machining time of graphite electrode is 58% faster than that of copper electrode. As a result, processing time is greatly reduced and manufacturing costs are reduced.

The design of graphite electrode is different from that of traditional copper electrode. Many die factories usually have different reserves for rough machining and finishing of copper electrodes, while graphite electrodes use almost the same amount, which reduces the number of CAD/CAM and machine machining. For this reason alone, it is enough to greatly improve the precision of mold cavity.

Graphite has superior properties that copper cannot match:
1. Processing speed: high-speed milling rough machining is 3 times faster than copper; High speed milling finishing is 5 times faster than copper
2. Good machinability, able to achieve complex geometric modeling
3. Light weight, less than 1/4 of the density of copper, easy to clamp the electrode
4. The number of single electrodes can be reduced, because combined electrodes can be made together
5. Good thermal stability, no deformation and no machining burr
