SENYAT QB400 WIRE EDM MACHINE

Technical Description

The SENYAT QB400 Wire EDM Machine is a precision CNC-controlled wire electrical discharge machining system designed for high-accuracy metal cutting applications. This compact machine features a cantilever-type structure with stepper motor-driven X and Y axes equipped with synchronous belts and THK linear guides for reliable positioning. The machine accommodates workpieces up to 400mm in thickness and 600kg in weight, with a maximum taper cutting capability of 6 degrees per side, making it suitable for complex geometries. Operating specifications include wire speeds ranging from 1-15 m/s with frequency conversion adjustment, an overall processing speed of 60 mm²/min and maximum cutting speed of 180 mm²/min. The QB400 achieves exceptional precision with composite machining accuracy of ±0.005mm, surface roughness as low as Ra 1.0µm, and conformance deviation of ±0.005mm per 30 pieces. The machine incorporates double-sensor closed-loop control for automatic wire tension management with real-time tension value display, eliminating the need for wire guides during operation. Its automatic wire winding and tightening system on the drum simplifies setup and reduces operator intervention. The 17-inch LCD display supports Chinese and English languages, with max work current of 6A and pulse width ranging from 2-62µs. Weighing 3,527.4 lbs, the QB400 delivers industrial-grade precision comparable to brass wire cutting machines, making it ideal for demanding applications in automotive, aerospace, and electronics manufacturing.
