EDM cutting is always through the entire workpiece. The reduced dielectric flow avoids distorting the wire during these skim passes. Because the electrical discharge erodes by the wire and the workpiece, wire EDM machines use a spool of wire that’s continuously moving to present a fresh discharge path in the cut. An electrical discharge (spark) is created between an electrode which is usually a wire, and the piece to be machined. As a result of the dielectric fluid, usually a hydrocarbon oil into which both the cathode and the workpiece are immersed, the minute chips produced by the process wash away from the piece. These costs can sometimes be softened by the fact that almost all wire EDM machines are designed to operate unattended, save for loading and unloading. The tool and workpiece must be electrically conductive and a small gap is maintained in between them. And, while the process uses no force and thus does not cause burrs and can be used on delicate items, the possibility of thermal stress is certainly present. CNC wire EDM is performed AFTER heat treatment so that the finished dimensions are not affected. Terms and Conditions, There is usually a low conductive liquid medium between the two, such as deionized water, which is continually flushed as the work progresses.
