TOPSCNC DK7750ZA WIRE EDM MACHINE

The TOPSCNC DK7750ZA CNC Wire EDM Machine is a high-precision, multi-axis electrical discharge machining system designed for accurate metal cutting applications. Featuring an X-axis travel of 19.69 inches (500 mm) and a Y-axis travel of 24.80 inches (630 mm), this machine provides a robust work envelope suitable for a wide range of industrial components. The CNC control system, specifically the DQE-DC-01, ensures reliable and precise operation, supporting simultaneous 4-axis control for complex cutting tasks. The machine utilizes a stepper motor drive for X, Y, U, and V axes, delivering a minimum control resolution of 0.001 mm and achieving machining precision of up to ±0.015 mm. Maximum wire feed rate is adjustable from 1 to 11.4 m/sec, while the maximum machining speed reaches 220 mm²/min, with surface roughness as fine as Ra ≤ 0.9 μm after five cuts. The DK7750ZA supports molybdenum wire diameters from φ0.15 to φ0.20 mm, with a recommended size of φ0.18 mm. It can handle workpieces up to 400 mm thick and weighing up to 1600 kg, with a maximum taper angle of 60° for workpieces up to 100 mm thick. The system operates on a standard 380V, 3-phase, 50Hz power supply, with a maximum working current of 10A and power consumption of 0.7 kW. Equipped with a 90L water tank, paper filter, and Italy pump for efficient filtration, the machine also features a closed protective cover for operator safety. The robust construction, industrial-grade controller, and advanced wire cutting technology make the DK7750ZA ideal for demanding precision machining environments.
