The BAOMA DK7740D Wire EDM Machine is a precision CNC-controlled electrical discharge machining system designed for high-accuracy cutting of complex metal parts and molds. Featuring an X-axis travel of 19.69 inches (500 mm) and a Y-axis travel of 30.91 inches (785 mm), this machine provides a large worktable size and stable movement for efficient processing of sizable workpieces. The CNC control system ensures precise positioning and reliable automation, supporting advanced functions such as multi-cutting, taper processing, and automatic wire threading. The machine is capable of handling workpieces up to 500 mm in thickness and supports a maximum taper angle of ±3° for plates up to 100 mm thick. It utilizes a wire diameter range of 0.15–0.2 mm and achieves a maximum cutting speed of up to 120 mm²/min, with a surface roughness as fine as 1.5 μm after three cutting passes. The adjustable wire guide frame and robust machine structure contribute to smooth wire movement and consistent machining quality. The DK7740D operates on a 3N-380V/50Hz power supply, with a rated power consumption of 3 KVA, and is equipped with a working solution reservoir of 56 liters. The controller type is BMW-2008, providing user-friendly operation and integration with standard CAD software. Additional features include automatic edge finding, centering, and power loss memory, ensuring operational safety and efficiency. The machine dimensions are 1500×1000×1850 mm, with a total weight of 2000 kg, making it suitable for industrial environments requiring high precision and reliability in wire EDM applications.
