The JZ DK7745 Wire EDM Machine is a high-precision CNC-controlled electrical discharge machining system designed for accurate and efficient metal cutting. Featuring an X-axis travel of 17.72 inches (450 mm), Y-axis travel of 21.65 inches (550 mm), and Z-axis travel of 15.75 inches (400 mm), this machine provides robust work envelope capabilities for a wide range of industrial applications. The worktable size measures 500×750 mm, supporting a maximum workpiece weight of 450 kg, ensuring stability and versatility during operation. The DK7745 utilizes a molybdenum wire electrode with a diameter range of 0.12–0.18 mm (customizable up to 0.18 mm), delivering a maximum cutting speed of over 100 mm²/min and achieving a best surface roughness of less than Ra2.5 μm. Precision is maintained at ±0.015 mm when cutting complex shapes such as octagons, meeting stringent quality standards. The machine supports a maximum cutting taper of 6°–60°/80 mm, with optional configurations available for increased taper angles. It operates on AC380V/220V power supply with a consumption of ≤2 kW and is equipped with a high-column design featuring an electric lift for precise adjustment of the guide wheel gap. The DK7745 is built with a precise ball screw linear guide track for enhanced accuracy and durability. Submerged cutting is supported, allowing for improved machining performance and surface finish. Auto threading is not included. The machine is CE and ISO certified, backed by a one-year warranty, and is packaged in a wooden container for secure shipping. Its overall dimensions are 1865×1520×1700 mm, and it weighs 1650 kg, making it suitable for demanding production environments.
