BAOMA BM320E WIRE EDM MACHINES

Technical Description

The BAOMA BM320E Wire EDM machine features a CNC control system with a working travel of 9.84 inches (X-axis) and 12.6 inches (Y-axis), translating to approximately 250 x 320 mm table travel. It is equipped with a highly precise wire-cutting mechanism capable of handling wire diameters from 0.15 to 0.2 mm, powered by a maximum working current of 6 A and a wire speed range of 5 to 11 meters per minute. The machine supports a maximum cutting thickness of 300 mm and can achieve cutting tapers up to ±30° for materials up to 100 mm thick. Surface finish quality is excellent, achieving roughness of ≤2.5 µm on a single cut and ≤1.2 µm with multi-cutting, maintaining a precision tolerance of ≤0.012 mm. It uses a water-based BM2 or BM4 dielectric solution in a 56 to 100-liter tank, ensuring stable machining conditions. Structural components include precision steel linear guideways and high-quality ball screws sourced from Taiwan, contributing to superior motion accuracy and rigidity. The control system runs BMXP software on a Windows XP platform, enabling features such as taper processing, shape interpolation, auto edge finding, and wire-break handling. Additional functionalities include automatic wire tension adjustment, motorized Z-axis control, ‘C’ type wire frames, and USB connectivity for data transfer and programming. The machine supports a load capacity of up to 300 kg on the worktable and operates on a rated power of approximately 3 KVA with voltage supply options between 220-415 V AC. Its modular internal design enhances maintainability and minimizes downtime, making it suitable for precision machining applications in tool and die industries and complex part manufacturing.
