Excellent carbon graphite electrode

(1) The increasing complexity of mold geometry and the diversification of product applications lead to higher and higher requirements for the discharge accuracy of spark machines. The advantages of graphite electrodes are that they are easier to process, have high EDM removal rate, and have low graphite loss. Therefore, some customers of Qunji spark machine have abandoned copper electrodes and switched to graphite electrodes. In addition, some electrodes with special shapes cannot be made of copper, but graphite is easier to form, and copper electrodes are heavier and not suitable for processing large electrodes.
(2) Graphite electrodes are easier to process, and the processing speed is significantly faster than copper electrodes. For example, the use of milling technology to process graphite is 2 to 3 times faster than other metal processing and does not require additional manual processing, while copper electrodes require manual grinding. Similarly, if a high-speed graphite machining center is used to make electrodes, it will be faster and more efficient, and there will be no dust problems. During these machining processes, choosing tools and graphite with appropriate hardness can reduce tool wear and copper electrode breakage. If the milling time of graphite electrode and copper electrode is compared in detail, graphite electrode is 67% faster than copper electrode. In general EDM, the machining of graphite electrode is 58% faster than that of copper electrode. As a result, processing time is greatly reduced, and manufacturing costs are also reduced.
(3) The design of graphite electrodes is different from that of traditional copper electrodes. Many mold factories usually have different allowances for roughing and finishing of copper electrodes, while graphite electrodes use almost the same allowance, which reduces the number of CAD/CAM and machining times, for this reason alone, It is enough to greatly improve the accuracy of the mold cavity.
