Good price and quality graphite electrode material refers to a kind of high-temperature resistant graphite conductive material made of petroleum coke and asphalt coke as aggregate and coal asphalt as binder through raw material calcination, crushing and grinding, batching, kneading, molding, roasting, impregnation, graphitization and mechanical processing. It is called artificial graphite electrode (graphite electrode for short), It is different from the natural graphite electrode prepared with natural graphite as raw material.

Advantages of good price and quality graphite electrode material

(1) The increasing complexity of die geometry and the diversification of product applications lead to higher and higher requirements for the discharge accuracy of spark machine. The advantages of good price and quality graphite electrode material are easy processing, high removal rate of EDM and small graphite loss. Therefore, some customers of group based spark machine give up copper electrode and use graphite electrode instead. In addition, some electrodes with special shapes cannot be made of copper, but graphite is easier to form, and the copper electrode is heavy, which is not suitable for machining large electrodes. These factors cause some customers of group based spark machines to use graphite electrodes products.

(2) Good price and quality graphite electrode material is easy to process, and the processing speed is significantly faster than copper electrode. For example, using milling process to process graphite, its processing speed is 2 ~ 3 times faster than that of other metals, and no additional manual treatment is required, while copper electrode needs manual grinding. Similarly, if the high-speed graphite machining center is used to manufacture the electrode, the speed will be faster, the efficiency will be higher, and the dust problem will not occur. In these processing processes, the selection of tools and graphite with appropriate hardness can reduce the wear loss of tools and the damage of copper electrode. If the milling time of graphite electrode is compared with that of copper electrode, graphite electrode is 67% faster than copper electrode. In general, the processing with graphite electrode is 58% faster than that with copper electrode. In this way, the processing time is greatly reduced and the manufacturing cost is reduced.

(3) The design of  goog price and quality graphite electrode material is different from that of traditional copper electrode. Many mold factories usually have different reservations in the rough machining and finishing of copper electrode, while graphite electrode uses almost the same reservation, which reduces the times of CAD / CAM and machining. For this reason alone, it is enough to improve the accuracy of mold cavity to a great extent.
