We use EDM Wire at Cougar RED as the technology is ideal for working with materials that are difficult to machine by other methods.

Electrical Discharge Machining – Wire (EDM-Wire) is where a thin single-strand metal wire, is fed through the workpiece, submerged in a tank of dielectric fluid and has electrical discharges passed through. The subsequent sparking process removes material from the workpiece until the desired shape is achieved. The process is precision programmed and controlled to very impressive tolerance. We use Agie Charmilles EDM technology as it is considered amongst some of the best in the industry.
