Wire EDM (Electrical Discharge Machining) is a non-contact precision cutting process that uses a thin, electrically charged wire to erode material via electrical discharges. The process occurs in a dielectric fluid, which flushes away debris and prevents overheating.

Wire EDM can cut electrically conductive materials, including hardened steels, aluminum, brass, titanium, tungsten, Inconel, carbide, and exotic alloys. The process works on materials up to 16 inches thick with precision tolerances.

Wire EDM offers exceptional precision, with tolerances as tight as ±0.0001”. It is ideal for complex geometries, fine details, and hard-to-machine materials, producing burr-free finishes with no mechanical stress on the part.

Unlike CNC milling, Wire EDM does not require cutting forces, making it ideal for delicate parts. It excels in cutting hardened materials, achieving extreme precision, and eliminating the need for post-processing.

The speed of Wire EDM depends on material type, thickness, and required tolerances. Generally, it cuts at speeds ranging from 0.02 to 1.5 inches per minute, with faster speeds for softer materials and high-precision slower cutting for intricate designs.
