The BAOMA BM400A Wire EDM Machine is a high-precision CNC-controlled electrical discharge machining system designed for accurate and efficient wire cutting operations. Featuring a robust construction and advanced control technology, this machine delivers reliable performance for a wide range of industrial applications. The working table offers an X-axis travel of 12.6 inches (320 mm) and a Y-axis travel of 15.7 inches (400 mm), providing ample workspace for intricate cutting tasks. The CNC control system ensures precise movement and repeatability, supporting complex geometries and multi-axis operations. The machine utilizes a closed-loop design for enhanced accuracy and stability during cutting, with a maximum cutting thickness of up to 300 mm and a maximum taper angle of ±3° for parts up to 100 mm thick. It operates with a wire diameter range of 0.15–0.2 mm and supports water-based working solutions (BM2/BM4) for optimal cutting conditions. The system achieves a maximum cutting speed of 150 mm²/min, with surface roughness as low as 1.2 μm after multi-cutting. Equipped with a high-quality ball screw and linear guideway, the BM400A ensures smooth motion and long-term durability. The control software, based on the BMXP platform with a Windows XP operating environment, enables seamless integration with CAD software and offers advanced functions such as coordinate transformation, zoom, rotation, real-time tracking, and interpolation for straight lines and circular arcs. The machine also features automatic handling of short circuits and wire breaks, making it user-friendly and efficient for continuous production environments.
