BAOMA BM500H WIRE EDM MACHINES

Technical Description

The BAOMA BM500H Wire EDM Machine is a high-precision CNC-controlled wire electrical discharge machining system engineered for complex metal cutting applications. It features a travel distance of 15.75 inches (X-axis) and 19.69 inches (Y-axis), supporting a working envelope suited for precision components. The machine employs high-quality ball screws and steel linear guideways to ensure smooth, accurate motion with a maximum cutting thickness of approximately 500 mm depending on the variant. The BM500H uses a closed-loop control system with BMXP PM-K software running on a Windows XP platform, enabling seamless integration with CAD software such as AutoCAD for direct file uploads. It supports multi-axis (X, Y, U, V) synchronized movement for intricate taper and contour cutting. The machine's wire feed system features a double-direction intelligent automatic wire tension control to maintain consistent cutting quality. Wire diameter ranges from 0.15 to 0.2 mm, and the machine can operate at wire speeds of 5 to 11 meters per minute, with a maximum current of 6A for efficient spark erosion cutting. Surface roughness after multi-cutting can be as low as 1.2 µm, with dimensional precision tolerances near 0.012 mm. The structure is built with a rigid, enclosed casting design to minimize vibration and thermal distortion, and the control cabinet incorporates modular design for easy maintenance. The EDM process produces finely detailed parts without mechanical stress or heat damage, ideal for mold making and precision engineering.
