Advantages of POCO graphite compared to other graphite elect

May 21, 2019
POCO graphite electrode is recognized as the best EDM electrode material in the world. POCO graphite provides different grades of cost performance balance, which can provide high metal cutting rate and good wear resistance. The most popular grades are EDM-200 and EDM-3 for injection mold production.
Compared with other graphite electrodes, it is easier to machine, especially when processing high-difficult electrodes such as meshes and ribs, it is not easy to cause chipping, which can reduce the number of processing. The machining loss can be reduced during machining, and the machining efficiency will be increased accordingly. EDM has a high surface finish and low loss. POCO provides customers with surface finish gauges and EDM performance curve charts, allowing customers to choose the ideal processing speed and surface finish.
