BAOMA BM400C WIRE EDM MACHINE

Technical Description

The BAOMA BM400C is a high-performance CNC wire electrical discharge machining (EDM) machine engineered for precision metal cutting applications. This machine delivers a maximum cutting speed of 250mm²/min with exceptional wire efficiency, consuming only 0.01mm of wire diameter per 400,000mm² of material processed. The system accommodates wire diameters ranging from 0.15 to 0.2mm and maintains wire traveling speeds between 5-11 m/min. The machine features a compact work table measuring 420×650mm with X and Y-axis travel capabilities of 320×400mm respectively, capable of processing workpieces up to 300mm in thickness. It achieves outstanding precision tolerances of ≤0.012mm on octagon cuts and ±0.04mm on taper operations, with surface roughness ratings of ≤1.2μm. The maximum taper angle is ±3° per 100mm of plate thickness. The CNC control system incorporates closed-loop servo control utilizing MITSUBISHI or YASKAWA servo motors for superior accuracy and repeatability. The machine includes advanced features such as automatic short-circuit and wire-break handling, power-loss memory functions, auto edge-touching, and auto-centering capabilities. The 56-liter working reservoir supports the BM-06GP or BM2/BM4 water-based working solutions. Operating specifications include a maximum working current of 9A, 3-phase 380V/50Hz power supply with 3KVA consumption, and a total machine weight of 1700kg. The modular internal design facilitates easy maintenance and reduces failure probability.
