Wire EDM provides several additional benefits

Wire EDM provides several additional benefits. Wire EDM eliminates the need for grinding or other finishing procedures and is able to cut hardened materials with ease. Compared to conventional machining, parts are produced more economically, making it a replacement for form grinding. Also, machines contain complex geometry capabilities and have stacking abilities to machine multiple parts at the same time.


Wire EDM works in the presence of an energetic electrical field to remove materials through a series of rapidly recurring electric arching discharges between an electrode, also known as the cutting tool, and the work piece. The machines are able to slice through any electrically conductive material with electrical energized thin brass wire. This makes it useful for use on difficult-to-machine metals. However, electrical discharging machining only works with electrically conductive materials, which are usually ferrous alloys.


Wire electrical discharge machining, also known as wire EDM, is a process used to produce precision parts for a wide variety of applications. This non-traditional method allows manufacturers to produce and repeat required specifications with ease.


To create intricate profiles, these machines use rapid, controlled, repetitive spark discharges. Water is also an important component in wire EDM for multiple reasons. The wire-cut process uses water as its dielectric with the waters resistivity and other electrical properties carefully controlled by filters and deionizer units. Water is also responsible for the critical role of flushing away cut debris from the cutting zone.


When complete, wire EDM edges are smooth but matte and have virtually no burrs. The typical surface finish is between 16 and 64 micro inches, but can be as fine as 10 micro inches. Many industries value the work produced by wire EDM because it is able to achieve high accuracy and tighter tolerances compared to other machining methods. Such industries include aerospace, medical, defense, automotive and electric or semiconductor manufacturing.
