The BAOMA BM400H is a closed-loop CNC wire electrical discharge machine designed for precision cutting applications. This economical-type WEDM features a maximum cutting thickness of 300mm and a maximum cutting taper of ±3° for materials up to 100mm thick. The machine delivers a maximum cutting speed of 150mm²/min with wire speeds ranging from 5-11m/min, utilizing wire electrodes with a diameter of 0.15-0.2mm. The work table accommodates a maximum load of 400kg and measures 415x635mm, providing adequate workspace for various workpieces. Equipped with a BMW-3000 controller and BMXP software operating platform, the system achieves high precision machining with an octagon precision of ≤0.012mm and surface roughness as low as ≤1.2μm in multi-cutting operations. The machine operates on AC 3-phase power (220-415V, 50/60Hz) with a rated power consumption of 3kVA and maintains a 100L water tank capacity for coolant circulation. Its modular internal wiring design minimizes failure probability and facilitates maintenance. The BM400H incorporates high-quality ball screws and linear guideways for smooth operation, along with an adjustable wire guide frame for optimal cutting performance. With a total machine weight of 1700kg and X-axis travel of 320mm and Y-axis travel of 400mm, this system provides reliable precision cutting for tool and die manufacturing, aerospace components, and complex geometries requiring tight tolerances.
