You can experience the U6 H.E.A.T. Extreme Wire Electrical Discharge Machine (Wire EDM) the fastest in the industry. Its innovative EDM technology uses a 0.016” (0.400mm) coated wire to achieve the fastest feedrates possible— twice as fast as traditional 0.010" brass wire. The U6 can also be outfitted with wire sizes down to 0.004” (0.100mm) for the most precise cuts.
