The benefits of Using Wire and Sinker EDM for Machining

How EDM can improve accuracy and efficiency in manufacturing industries

Wire and sinker electrical discharge machining, better known as EDM, is the most accurate way to machine complex and intricate shapes. We find wire and sinker EDMs installed in the automotive, aerospace, electronics, die and mold, and other industries where micro tolerances and extreme precision are required. Based on material and part features, it can be difficult to machine some parts using traditional machining methods; that is where EDM machining has the upper hand.

There are various benefits to machining with wire and sinker EDM, one being the ability to machine with any material. While holding consistent tight tolerances, EDM machines can charge through even the most rigid materials, including tungsten, carbide, and titanium. EDM equipment can do this because there is no pressure against the workpiece, eliminating inaccuracies.

Wire EDMs use a thin, single strand of metal wire and de-ionized water, which allows the wire to cut through the material using heat and electrical sparks. These machines are best for companies looking to cut entirely through material for full runs, excursion of dies, or blank punching. Differently, Sinker EDM machines use an electrode and workpiece submerged in oil or dialectic water to generate sparks that shape the material. Although highly accurate, sinker EDMs do not cut through the material; therefore, they are best for molds, die sets, and various industries such as medical.
