Graphite is able to achieve electrode wear of less than 1% in relation to the depth of cut, while working to more aggressive machine parameters. This means, unlike copper, the high amperage and longer on-times actually preserve the graphite electrode.
Graphite is a fairly porous material, and so it can absorb coolant and act as a "coolant sponge," which will cause problems with finished parts. Inside the machine and on the tooling, the coolant can actually react with the graphite dust and create an abrasive slurry, which will cause problems while machining.
Crushing machines; Every step in the production process can put workers at risk. Electrodes can pose a severe hazard by exposing workers to electric shock burns, explosions and injuries resulting just from maneuvering these massive columns. ...

The first consideration when preparing to machine graphite is the types of tools that can be used. Graphite is abrasive and will cause severe wear on uncoated metallic tools. Preferable tools are diamond-edged, though tungsten carbide tools may be used as well. High-speed steel can be used but will wear out quickly, which limits its use.
