Electrical discharges jump between the wire and the material, removing material along a contour programmed from a drawing or 3D model. Because the wire does not touch the workpiece, wire cutting produces a precise contour even in hardened steel. We grind the datum surfaces beforehand on our Okamoto grinder and cut the contour on our Mitsubishi FA20 wire EDM machine.<\/p><\/div><\/details>\n<details><summary><h3>Can you cut hardened or very hard steel?<\/h3><\/summary><div class=\"ee-odp\"><p>Yes. The wire does not make mechanical contact with the part, so material hardness after hardening is not an obstacle.

Both methods are electrical discharge machining processes. At ECAD, we operate a Mitsubishi FA20 wire EDM machine and use it to perform wire EDM.<\/p><\/div><\/details>\n<details><summary><h3>How large a part can you cut on the Mitsubishi FA20 wire EDM machine?<\/h3><\/summary><div class=\"ee-odp\"><p>We cut contours within an X\/Y axis travel range of 500 \u00d7 350 mm, with a Z-axis travel of 300 mm and a workpiece weight of up to 1,500 kg. These are the machine parameters. When quoting based on your drawing, we confirm whether your part will fit and what contour we can achieve.<\/p><\/div><\/details>\n<details><summary><h3>What is wire EDM used for?<\/h3><\/summary><div class=\"ee-odp\"><p>Wire EDM is used for precise contours in hard and hardened materials, including in cutting and forming tools, wherever a contour is difficult to achieve by milling or turning.<\/p><\/div><\/details>\n<details><summary><h3>How much does wire EDM cost?<\/h3><\/summary><div class=\"ee-odp\"><p>We quote based on a drawing or 3D model, not from a price list.

Electrical discharges jump between the wire and the material, removing material along a contour programmed from a drawing or 3D model.
