About Our Plunge and Wire Cut Electrical Discharge Machining Process

Wire EDM occurs when a single strand of thin metal wire is fed through the workpiece, and then the two are submerged in dielectric fluid. This technique is used to cut thicker plates and to make punches, tools, and dies from hard metals. Wire EDM is also known as wire cut electrical discharge machining and wire cutting.

Plunge EDM, also known as sinker EDM, cavity type EDM or volume EDM, is when an electrode and workpiece, both connected to a power source, are submerged into an insulating liquid. The power source generates an electrical potential between the two parts, and sparks jump as the electrode moves closer to the workpiece. Dielectric breakdown occurs in the fluid, where a plasma channel forms.

The highly skilled engineers at Aerofab are experts in both of these processes, as well as other types of electrical discharge machining.

What is Electrical Discharge Machining?

Electrical Discharge Machining (EDM) uses rapidly-released electrical discharge, or sparks, to cut intricate shapes or very small holes into the workpiece. EDM is the chosen cutting technique used when the metal material is too hard for conventional twist-drill machining. This process is also known as spark eroding, spark machining, die sinking, burning, wire burning or wire erosion.
