Introduction and application of EDM graphite Aug 07, 2018

The EDM is now the fourth most popular processing method, leading behind milling, turning and grinding.

Compared with the traditional copper electrode, the application of balanced EDM graphite material has the following advantages:

1. The price of a balanced graphite compared to about 25% of the same volume of copper electrodes. 2. Faster than copper electrode processing speed 3-5 times.

The machined surface is smooth.

3. Good machining precision and polishing.

4. The density of graphite is only 1/5 copper.

It is more suitable for the production of larger electrodes.

5. Used as electric spark electrode, this only consumes 1/3-1/5 copper electrode.

The spark decomposition of the coated cemented carbide electrode compensates for the loss. XRD Graphite can be supplied with a wide variety of EDM graphite according to customer applications.
