MACHIMAX DK7780 WIRE EDM MACHINES

Technical Description

The MACHIMAX DK7780 Wire EDM machine features a CNC control system and provides X-axis and Y-axis travels of 33.46 inches and 45.28 inches respectively, suitable for precise wire electrical discharge machining. It supports a maximum cutting thickness of up to 800 mm and achieves cutting accuracy around 0.015 mm with surface roughness typically between 1.2–2.5 µm. The machine uses fine molybdenum wire between 0.13 and 0.2 mm diameter, operating with a maximum processing current of approximately 6 to 10 A, and consumes about 3 kW of power. Its table size and travel vary slightly by source but generally support large workpieces up to 2000 kg in weight. Advanced functions include automatic cutting tracking, real-time automatic return on short circuit, power failure protection, and multi-cut processing capabilities facilitated by a Windows-based control platform compatible with AutoCAD software. The DK7780 is designed for high precision applications such as punch and plastic molds, powder metallurgy parts, silicon steel sheets, and tiny or complex groove machining in industries like electronics, precision tooling, and military manufacturing. The machine frame incorporates a robust casting structure with ball screw-driven X and Y axes for high stiffness and accuracy, featuring an industrial-grade CNC system for reliable, high-speed cutting typically reaching around 150 mm²/min. The modular internal wiring and centralized lubrication system enhance durability and maintenance convenience. Overall dimensions are approximately 1950 × 2050 × 2250 mm with a typical weight near 4000–5200 kg depending on the configuration.
