JZ DK7780 WIRE EDM MACHINES

Technical Description

The JZ DK7780 is a CNC wire electrical discharge machining (EDM) system engineered for precision cutting of hardened materials and complex geometries. This machine features substantial travel capabilities with an X-axis travel of 31.5 inches (800mm), Y-axis travel of 47.2 inches (1200mm), and Z-axis travel of 59.1 inches, enabling processing of workpieces up to 600mm in thickness. The system utilizes a submerged cutting configuration, maintaining the workpiece and electrode wire in a water-based emulsion bath that enhances precision and surface finish. Equipped with advanced CNC control utilizing the AutoCut/X8 system, the DK7780 delivers cutting speeds up to 180mm²/min with cutting accuracy of ±0.015mm. The machine accommodates electrode wire diameters of 0.13-0.2mm with maximum cutting currents reaching 10A. Surface roughness capabilities achieve 1.2-2.5μm Ra, meeting stringent dimensional requirements. The worktable measures 1000×1370mm with a maximum load capacity of 2000kg, supported by high-quality ball screws and steel linear guideways for durability and repeatability. Power requirements are 3.3kW at 220/380/415V, 50/60Hz operation. Without automatic threading, manual setup is required, though the machine compensates through its precision performance characteristics. Weighing approximately 4000-6700kg depending on configuration, the DK7780 serves industries requiring precision mold manufacturing, punch tooling, and intricate component machining.
