This method of cutting is incredibly precise and can be used to cut almost any electrically-conductive material. To accomplish cutting, a thin EDM wire is suspended between two mechanical guides. Then, it’s electrically charged, forming an electrode. To accomplish cutting, a thin EDM wire is suspended between two mechanical guides. Then, it’s electrically charged, forming an electrode. When the EDM metal cutting comes near the wire and the workpiece material, it creates sparks that cut the material way, leaving behind a negative imprint.

During the cutting process, the workpiece and wire are submerged in deionized water, which allows the debris from cutting to be washed away. The charged wire itself never actually contacts the material that is being cut, so wire cutting services material can be used to create extremely small, delicate components that require a level of precision that is impossible to accomplish with traditional CNC machining.
