The JZ DK7720 Wire EDM Machine is a high-precision CNC wire-cut electrical discharge machining system designed for accurate and efficient metal cutting. Featuring an X-axis travel of 7.87 inches (200 mm), Y-axis travel of 9.84 inches (250 mm), and Z-axis travel of 7.87 inches (200 mm), this machine offers a robust work envelope suitable for a wide range of industrial applications. The worktable size measures 270×420 mm, supporting a maximum workpiece weight of 100 kg and a maximum cutting thickness of 200 mm. The DK7720 operates with a power rating of up to 2 kW and is compatible with both 220V and 380V power supplies, making it adaptable for various electrical environments. The machine utilizes a water-based emulsion as its working fluid and supports electrode wire diameters from 0.12 mm to 0.18 mm, ensuring fine and controlled cutting. Maximum cutting speed reaches up to 100 mm²/min, with a machining accuracy of ±0.015 mm and an optimal surface roughness of ≤2.5 μm. The DK7720 is equipped with a ball screw linear guide track for smooth and precise movement, and its column design allows for electric lift adjustment of the guide wheel gap. Taper processing is optional, supporting up to 6°/80 mm. The machine is submerged, enhancing cutting stability and precision. Auto threading is not available on this model. The overall dimensions are approximately 1350×950×1400 mm, with a machine weight of 800 kg. The DK7720 is CE and ISO9001 certified, ensuring compliance with international quality standards.
