In wire electrical discharge machining (WEDM), also known as wire-cut EDM and wire cutting, a thin single-strand metal wire (.010" DIA), usually brass, is fed through the workpiece, submerged in a tank of dielectric fluid, typically deionized water. Our current machines allow us to cut pieces up to 8 inches thick, and is ideal for punches, tools, and dies from hard metals that are difficult to machine with other methods. The wire, which is constantly fed from a spool, is held between upper and lower diamond guides. The guides, usually CNC-controlled, move in the x–y plane. On most machines, the upper guide can also move independently in the z–u–v axis, giving rise to the ability to cut tapered and transitioning shapes (circle on the bottom square at the top for example). The upper guide can control axis movements in x–y–u–v–i–j–k–l–. This allows the wire-cut EDM to be programmed to cut very intricate and delicate shapes. Some advantages include:

1. Great for: precision gages and templates, keyways, shaft and collet slots, splitting tubes, gears, internal splines, hexes, cams, extrusion molds, punches and dies from one piece of tool steel, short run stampings from stacked material, and many other exotic shapes
2. Angles up to 45 Degrees
3. Independent axis machining (Different shape on top and bottom of the piece)
4. Exotic Materials (If it conducts electricity it can be cut)
5. No stress on the part, and no burrs
6. Great solution for those difficult to machine parts
