Graphite is very common in nature, and graphene is the most powerful material known to human beings, but it may still take years or even decades for scientists to find a way to turn graphite into a large high-quality graphene “film”, so that they can be used to make all kinds of useful materials for human beings. According to scientists, graphene has a series of unique characteristics in addition to its extraordinary firmness. Graphene is also the most excellent material known for its electrical conductivity, which makes it also have great application potential in the field of microelectronics.
Researchers even see graphene as a silicon substitute that could be used to make supercomputers of the future. Graphite electrode is easy to process, and the processing speed is faster than copper electrode. For example, when using milling technology to process graphite, its processing speed is 2-3 times faster than that of other metals, and no additional manual treatment is needed, while copper electrode needs manual grinding. Similarly, if high-speed graphite machining center is used to make electrodes, the speed will be faster, the efficiency will be higher, and there will be no dust problem.
In these processes, choosing proper hardness tools and graphite can reduce the wear loss of tools and the damage of copper. If the milling time of graphite electrode is compared with that of copper electrode, graphite is 67% faster than that of copper electrode. In general, the machining speed of graphite electrode is 58% faster than that of copper electrode. In this way, the processing time is greatly reduced, and the manufacturing cost is also reduced.
Graphite in graphite electrode has the following high quality characteristics that copper can’t match：
1. Processing speed: three times faster than copper in high-speed rough milling; five times faster than copper in high-speed finish milling 2. It has good machinability and can realize complex geometric modeling 3. Light weight, less than 1 / 4 of the density of copper, easy to clamp the electrode
4. It can reduce the number of single electrode, because it can be bundled into combined electrode
5. Good thermal stability, no deformation and machining burr
