regular power graphite electrodes

Graphite has the characteristics of high high temperature strength, low thermal expansion coefficient, good processability, and good thermal conductivity. Therefore, regular power graphite electrodes are widely used in metallurgy, electric furnaces, electric discharge machining and other fields. In the field of EDM, the development of new regular power graphite electrodes and processing technology has expanded the application range of EDM and improved the performance of EDM.

Compared with copper regular power graphite electrodes, regular power graphite electrodes have low consumption, fast processing speed, good processability, high processing accuracy, small thermal deformation, light weight, easy surface treatment, high temperature resistance, and processing temperature. High, regular power graphite electrodes can be bonded and other advantages.

Although graphite is a very easy to cut material, the graphite material used as regular power graphite electrodes for EDM must have sufficient strength to avoid damage during operation and EDM. At the same time, the shape of regular power graphite electrodes (thin wall, small rounded corners, sharp changes) also puts forward higher requirements on the grain size and strength of regular power graphite electrodes, which leads to the use of regular power graphite for EDM. The graphite material of electrodes must have enough strength to avoid damage during operation and EDM. Graphite workpieces are easy to break during processing, and the tools are easy to wear. Therefore, how to prevent the workpiece from breaking, improve the surface quality, and reduce the cost of the tool has become an important issue in the processing of regular power graphite electrodes.

In order to meet the needs of processing simple shape regular power graphite electrodes, traditional turning, milling and grinding methods are usually used. However, in recent years, the requirements for the geometric complexity of regular power graphite electrodes have continued to increase. The high-speed machining surface quality and high machining accuracy make the high-speed machining of regular power graphite electrodes a hot spot for mold EDM. Many manufacturers have introduced graphite high-speed machining centers.
