The TOPSCNC DK7750ZAB is a precision CNC wire EDM machine designed for high-accuracy metal cutting applications. Featuring X-axis travel of 24.8 inches and Y-axis travel of 19.7 inches (500×630mm), it delivers a generous work envelope for complex part production. The machine utilizes advanced CNC control via the DQE-DM-03 system, enabling automated precision cutting with multiple simultaneous axes operation. This wire EDM machine achieves exceptional machining precision of ≤0.015mm with maximum cutting speeds reaching approximately 300mm²/min under optimal conditions. The system supports taper cutting angles up to ±6° for applications requiring angled profiles. Surface finish quality ranges from Ra≤2.3μm with single-cut passes to Ra≤1.2μm with three cuts, ensuring superior edge quality. The DK7750ZAB accommodates maximum cutting thickness of 500mm with a work table load capacity of 800kg. It employs molybdenum wire electrodes ranging from Φ0.12mm to Φ0.20mm diameter, with wire feed speeds between 5-11 m/s. The machine operates on regulated cutting current of 6-8A for stable continuous operation, with peak capability up to 10A. Key features include a 100L or 60L integrated water tank system with filtration, industrial-grade PC/104 motherboard architecture, and automatic functions for edge positioning and power-loss recovery. Weighing approximately 2,300kg, this machine integrates high-precision ball screws and steel linear guideways for repeatable accuracy in production environments.
