The GMT-WC Series represents the pinnacle of spark erosion technology, engineered specifically for the rigorous demands of tool-and-die making and aerospace component manufacturing. Utilizing a high-speed, de-ionized water submerged system, this machine achieves an exceptional surface finish of Ra ≤ 0.8 µm, virtually eliminating the need for secondary polishing.

The robust mechanical structure supports a wide range of workpiece dimensions, while the precision-driven UV axis allows for complex taper cutting of up to ± 15°, essential for specialized extrusion dies and mold inserts. Equipped with an intuitive, Windows-based CNC controller and an optional Automatic Wire Threading (AWT) system, the series maximizes “lights-out” productivity and ensures a positioning accuracy within ± 0.005 mm. Whether cutting hardened tool steel or exotic alloys, the GMT-WC provides the thermal stability and discharge control required for your most critical tolerances.
