EDM is now the fourth most popular machining method, leading behind milling, turning and grinding.
Comparing with the traditional copper electrode,isostatic graphite materials for EDM application have the following advantages:
1．The price of isostatic graphite is around 25% compared with the same volume copper electrode.
2．The machining speed is 3-5 times faster than copper electrode. The machined surface is smooth.
3．Good Machining Precision and easy polishing.
4．The density of graphite is only 1/5 of copper. It’s more suitable in the production for larger electrodes.
5．Used as EDM electrode,which consumption is only 1/3-1/5 of copper electrode. The coating of spark decomposition of carbide compensates electrode is loss.
XRD Graphite can supply all kinds of EDM graphite according to the customers’ application.
