TOPSCNC DK7780ZAC WIRE EDM MACHINE

Technical Description

The TOPSCNC DK7780ZAC Wire EDM Machine is a high-precision CNC-controlled electrical discharge machining system designed for accurate and efficient wire-cutting operations. Featuring an X-axis travel of 31.5 inches (800 mm) and a Y-axis travel of 39.4 inches (1000 mm), this machine delivers reliable performance for a wide range of industrial applications, including mold making, tooling, and precision component manufacturing. The machine is equipped with advanced CNC control (DQE-DC-01), ensuring precise axis movement, consistent cutting accuracy, and ease of operation. It supports maximum cutting thicknesses up to 800 mm and offers a maximum cutting speed of up to 350 mm²/min, with regular stable cutting speeds around 170 mm²/min depending on surface finish requirements. The electrode wire diameter ranges from Φ0.12 to Φ0.20 mm, allowing flexibility for various cutting needs. Surface finish quality is excellent, achieving Ra ≤2.3 μm for a single cut, Ra ≤1.8 μm for two cuts, and Ra ≤1.5 μm for three cuts. The machine incorporates a robust industrial PC/104 motherboard, interior double-impulse and multiple-circuit design, and high-speed signal filtering for improved discharge control and reduced wire wear. The working table measures 850×1500 mm, supporting heavy workloads, and the overall machine dimensions are 2540×2340×2400 mm. With a maximum cutting current of 15 A and a rated power of ≤1 kVA, the DK7780ZAC operates efficiently in standard industrial environments. The system also features automatic short-circuit and wire-break handling, auto-edge positioning, and memory functions for uninterrupted processing. This machine is ideal for high-accuracy cutting of complex shapes in conductive materials, offering durability, stability, and superior surface finish.
