Our friends at Titans of CNC make a Precision Punch and Die that Fit together Perfectly using wire EDM additive technology.
The fundamental steps of electrical discharge machining are really fairly straightforward. Between two electrodes, an electrical discharge (spark) occurs (solid electric conductors). Typically, the workpiece electrode is referred to as the workpiece and the tool electrode as the electrode. The spark is tangible proof that electricity is moving. The extreme heat produced by an electric spark, which may reach temperatures of 8000 to 12000 degrees Celsius, can melt or vaporize practically any conductive material. The very small gap between the two electrodes, which never makes contact with one another, is where this quick, repetitive electrical current discharge occurs. As the electric discharge occurs up to millions of times per second, adaptive machine controls keep the spark gap (also known as the discharge gap or electrode gap) at a consistent, stable distance.
