Advantage

(1) the advantages of graphite electrode are easier processing, high discharge machining removal rate, graphite loss is small, therefore, some group based spark machine customers gave up the copper electrode and instead of graphite electrode.In addition, some of the special shape of the electrode can not be made of copper, but graphite is easier to shape, and the copper electrode is heavy, not suitable for processing large electrode, these factors have caused some group based spark machine customer application of graphite electrode.

(2) graphite electrode is easier to process, and the processing speed is obviously faster than copper electrode.For example, graphite is processed by milling process, which is 2-3 times faster than other metals and does not require additional manual processing, while copper electrode needs manual grinding.Similarly, if you use a high-speed graphite processing center to make the electrode, it will be faster and more efficient, and there will be no dust problem.In these processes, the selection of suitable hardness tools and graphite can reduce tool wear and copper electrode damage.When comparing the milling time between the graphite electrode and the copper electrode, the graphite electrode is 67% faster than the copper electrode. In the discharge machining under general conditions, the processing time with the graphite electrode is 58% faster than that with the copper electrode.As a result, processing time is greatly reduced and manufacturing costs are reduced.

(3) the design of graphite electrode is different from that of traditional copper electrode.Many die factory usually in the copper electrode rough processing and finishing aspects have different reserved amount, and graphite electrode is used almost the same reserved amount, which reduces the CAD/CAM and machine processing times, for this reason alone, is enough to greatly improve the precision of mold cavity.
