TOPSCNC DK7780ZA WIRE EDM MACHINES

Technical Description

The TOPSCNC DK7780ZA Wire EDM Machine features a compact yet robust design with X-axis travel of 31.5 inches (800 mm) and Y-axis travel of 39.4 inches (1000 mm), accommodating a large work envelope suited for varied metal cutting tasks. It employs a CNC control system (DQE-DC-01) that supports high-precision linear guides and complex contour processing with up to 4-axis simultaneous control, facilitating accurate, taperable cuts with typical precision up to ±0.012 mm. The machine supports wire diameters ranging from 0.12 mm to 0.20 mm and can handle cutting thicknesses up to approximately 500-800 mm depending on configuration, with a maximum cutting speed reaching over 150 mm²/min and cutting currents up to 10-15 A, balancing speed and surface finish quality. The system integrates advanced features such as interior double-impulse and multiple-circuit discharge design for improved surface finish (as low as Ra 1.5 μm after multiple cuts), high-speed logical circuit control, electrolytic protection, and blue spark filtering to minimize arcing and ensure stable cutting performance. The DK7780ZA includes adjustable wire guides, a centralized lubrication system, and a water-based dielectric working solution with a tank capacity typically around 60-100 liters. Its industrial PC/104 motherboard-based control electronics ensure high reliability in demanding environments. The machine weighs approximately 2000-5000 kg and operates on a single or three-phase power supply with rated power around 1-3 kVA. Overall, the TOPSCNC DK7780ZA is designed for precision, durability, and versatility in wire EDM metal processing applications.
