CONCORD BM400C-C WIRE EDM MACHINES

Technical Description

The CONCORD BM400C-C is a precision CNC wire EDM machine engineered for high-accuracy metal cutting applications. It features a compact worktable measuring 420 x 650mm with controlled X and Y axis travel of 320mm and 400mm respectively, accommodating workpieces up to 300mm thick. The machine delivers exceptional machining accuracy of ±0.012mm and produces superior surface finishes with roughness ratings of ≤1.2μm. Equipped with servo control technology, the BM400C-C achieves maximum cutting speeds of 250mm²/min with 0.15-0.2mm diameter wire electrodes traveling at 5-11m/min. The CNC controller utilizes Japanese Mitsubishi servo control system with 4-axis synthesis capability (X, Y, U, V), enabling simultaneous cutting of different profiles at top and bottom surfaces. Resolution reaches 0.001mm with linear and circular interpolation. The machine incorporates precision linear motion guide ways and ball screws for enhanced rigidity and repeatability. It operates with a maximum working current of 9A and uses BM-06GP working solution with a 56-liter tank capacity. The worktable supports loads up to 400kg, while the entire machine weighs approximately 1400kg. Advanced features include automatic wire tension mechanisms, motorized Z-axis control, and auto shut-off at wire breakage. The system runs on a Windows XP operating platform with embedded BMXP software, enabling seamless integration with AutoCAD for profile generation and optimization. This configuration makes it ideal for precision tooling, stamping dies, and complex component manufacturing.
