The DK7725 Single Cutting Wire Cut EDM is designed for precision machining of conductive metal parts with a larger working range than the DK7720. It features a 340 × 520 mm worktable, 250 × 320 mm X/Y travel, 60 × 60 mm U/V travel, and supports workpieces up to 400 mm thick and 200 kg in weight. With ±0.03 mm positioning accuracy, ±0.005 mm repeat positioning accuracy, and 0.10–0.25 mm molybdenum wire, the DK7725 is suitable for mold parts, tooling, and general precision wire EDM cutting applications.
