We has been using graphite as electrode material for EDM sink eroding since the mid nineties.
We use high-speed CNC milling machines (type SATURN 2 and OPS 600) to manufacture graphite electrodes, which required for electro discharge machining. The necessary CNC programms are written in-house using GibCAM programming software.
