Graphite electrode refers to a resistance electrode made of petroleum coke and pitch coke as aggregates and coal pitch as binder. It is made by calcining raw materials, crushing and grinding, batching, kneading, shaping, roasting, impregnation, graphitization and mechanical processing. High-temperature graphite conductive materials are called artificial graphite electrodes (graphite electrodes for short) to distinguish them from natural graphite electrodes prepared from natural graphite.

What are the advantages of graphite electrodes?
(1) The increasing complexity of mold geometries and the diversification of product applications have led to increasingly higher requirements for the discharge accuracy of spark machines. The advantages of graphite electrodes are easier processing, high discharge machining removal rate, and low graphite loss. Therefore, some customers of Qunji EDM machines gave up copper electrodes and switched to graphite electrodes. In addition, some special-shaped electrodes cannot be made of copper, but graphite is easier to shape, and copper electrodes are heavier and are not suitable for processing large electrodes. These factors have led some Qunji spark machine customers to choose to use graphite electrodes.
(2) The design of graphite electrodes is different from traditional copper electrodes. Many mold factories usually have different roughing and finishing machining allowances for copper electrodes, while graphite electrodes use almost the same machining allowance, thereby reducing the amount of CAD/CAM and machining. This reason alone is enough to improve the accuracy of the mold cavity to a great extent.
(3) Graphite electrodes are easier to process and the processing speed is significantly faster than copper electrodes. For example, the milling process is used to process graphite, which is 2 to 3 times faster than other metal processing, and does not require additional manual processing, while copper electrodes require manual polishing. Similarly, if a high-speed graphite machining center is used to manufacture electrodes, it will be faster and more efficient, and there will be no dust problems. During these machining processes, selecting tools and graphite with appropriate hardness can reduce tool wear and copper electrode breakage. If we specifically compare the grinding time of graphite electrodes and copper electrodes, graphite electrodes are 67% faster than copper electrodes. In general electrical discharge machining, machining with graphite electrodes is 58% faster than machining with copper electrodes. In this way, processing time is significantly reduced and manufacturing costs are also reduced.
