What is electrical discharge machining?

Electrical Discharge Machining, or EDM, represents a precise non-contact machining technique that shapes workpieces through electrical spark erosion. Ideal for delicate projects, EDM exerts no cutting forces on the workpiece.

Electrical Discharge Machining FAQs

Both wire and sinker EDM can only be used on materials that can conduct electricity, because the electrode needs to be able to wear away the material. This limits the EDM process to metals.

Wire EDM machines can handle jobs that can be too intricate or delicate for other methods of machining, such as internal fillets, corners, or other very small and complex parts.

The EDM process consists of a metal part being submerged in dielectric fluid, where an electrically charged wire is then fed through the submerged metal component to make the precise cuts.
