【Abstract】 With the development of graphite technology, graphite electrodes have been widely used in our daily life. This article mainly introduces the summary and advantages of graphite electrodes and also lists more than a dozen well-known manufacturers for the reference of netizens.

Introduction to Graphite Electrodes

Graphite electrode is made of petroleum coke, pitch coke as aggregate, and coal tar pitch as binder, and is made by calcination of raw materials, crushing and grinding, batching, kneading, molding, roasting, impregnation, graphitization, mechanical processing, and other processes. Corrosion-resistant electrodes. High-temperature graphite conductive materials are called artificial graphite electrodes (referred to as graphite electrodes) to distinguish them from natural graphite electrodes prepared from natural graphite.

The main raw material for producing graphite electrodes is petroleum coke. Ordinary power graphite electrodes can add a small amount of pitch coke. The sulfur content of petroleum coke and pitch coke cannot exceed 0.5%. Needle coke is also required in the production of high-power or ultra-high-power graphite electrodes. The main raw material for the production of aluminum anodes is petroleum coke, and the sulfur content is controlled at no more than 1.5% to 2%. Petroleum Coke and pitch coke shall meet the relevant national quality standards.

Advantages of graphite electrodes

(1) The increasingly complex geometric shape of the mold and the diversification of product applications lead to higher and higher requirements for the discharge accuracy of the spark machine. The advantage of graphite electrode is that it is easier to process, the removal rate of EDM is high, and the loss of graphite is small. Therefore, some group spark machine customers have given up copper electrodes and switched to graphite electrodes. In addition, some special-shaped electrodes cannot be made of copper, but graphite is easier to form, and copper electrodes are heavy, which is not suitable for processing large electrodes. These factors have led some group-based spark machine customers to use graphite electrodes.

(2) Graphite electrodes are easier to process, and the processing speed is significantly faster than that of copper electrodes. For example, graphite is processed by milling, which is two to three times faster than other metals and does not require additional manual processing, while copper electrodes require manual grinding. Likewise, if a high-speed graphite machining center is used to manufacture the electrodes, it is faster and more efficient without dusting problems. In these processes, choosing tools and graphite with appropriate hardness can reduce tool wear and copper electrode damage. If you specifically compare the milling time of graphite and copper electrodes, graphite electrodes are 67% faster than copper electrodes. In general, graphite electrodes can be machined 58% faster than copper electrodes in EDM. As a result, processing time is greatly reduced, which also reduces manufacturing costs.

(3) The design of graphite electrodes is different from traditional copper electrodes. Many mold factories usually leave different allowances for rough machining and finishing machining of copper electrodes, while graphite electrodes use almost the same allowance, which reduces the number of CAD/CAM and machining. This alone is enough to improve the accuracy of the mold cavity to a large extent.
