Wire EDM machining is more accurate than laser, flame cut, or plasma. It imparts no force on the part, making Wire EDM machining capable of achieving very high tolerances for precise dimensions and accurate fit. It produces parts without burrs or distortion, saving time in secondary processing. 
Any electrically conductive material can be efficiently machined using Wire EDM machining, no matter how hard or fragile. It is ideal for specialty materials such as, timascus, moku-ti, mokume, damascus, and damasteel.
