The optimum tension is that just before breakage. Micro wire EDM (micro-WEDM) technique is a micro version of macro wire EDM. Wire EDM & Micro Wire EDM Today’s engineers are designing miniature components with extremely tight tolerances. Cutting Width (clearance): With its high tensile strength and stable ED characteristics, SP wire provides precise, fine ED cutting where the cutting width (clearance) is =20% narrower and the corner radius is smaller than that with tungsten wire. When applied correctly they all worked pretty good.

Read below to learn how our Microwaterjet® process eliminates the need for this cumbersome task. When you use wire EDM to machine thin materials, you must cut the parts in multiple layers to compensate for this slow cutting process. For most shops, this pushes their limits. A program is generated which drives the wire (or sinker electrode) along the designated tool path, and the resulting high frequency electrical discharges between the workpiece and the electrode erodes the specified path. We can handle small jobs while being equipped for large production contracts.
