Electrical discharge machining (EDM)

Electrical discharge machining (EDM)

Toyo Tanso provides a wide range of graphite materials for EDM.

Graphite materials are widely utilized as electrical discharge machining(EDM) electrodes for fabricating molds for die-casting, plastics and more. Graphite has the versatility to machine very large to small precision sizes used in the medical field.
Compared to copper electrodes , graphite electrodes offer excellent cutting performance and produce fewer burrs and similar issues, thereby enabling speed improvements in both cutting and EDM processes.
The TTK grades where developed has an ultrafine particle structure in the order of microns. In addition to cutting and EDM, it also has superior characteristics to wire EDM, which has been something that has conventionally been difficult for graphite materials.
It also exhibits great improvements in the production of fine surface finishes , the reduction of electrode wear and the processing of microscopic profiles, things that could be not achieved with existing graphite electrode materials.
