Wire EDM – Frequently Asked Questions
How does the EDM process work?
Wire Electrical Discharge Machining (EDM) is a non-contact, force-free industrial cutting process. In wire EDM, an electrical spark is used to cut different types of electrically-conductive materials, such as metals, carbides, alloys, and graphite.
In Wire EDM cutting, the material to be cut is submerged in a dielectric cutting fluid, usually deionized water. A thin single-strand wire electrode is placed over the material on a CNC-controlled robotic guidance system. An electric current is run through the wire, creating an electrical spark of intense heat (8000-12000°C).
The electrical spark cuts the material by removing the metal content through melting and vaporization. The robotic guidance system guides the wire and the spark it generates over the cutting path for the desired pattern, but the wire does not touch the material. At the same time, the dielectric cutting fluid cools the material and flushes away particles that have been cut from it.
