TOPSCNC DK7725Z WIRE EDM MACHINES

Technical Description

The TOPSCNC DK7725Z Wire EDM machine is a high-precision CNC wire cutting tool designed for efficient metal processing. It features an X-axis travel of 9.84 inches and a Y-axis travel of 12.6 inches (250×320 mm), respectively, with additional U and V axis travel ranges of 70×70 mm to enable four-axis simultaneous control for complex taper and 3D contouring. The machine supports wire diameters of 0.15 to 0.20 mm (with 0.18 mm recommended) and achieves a wire feeding speed adjustable from 1 to 11.4 m/s. Precision is maintained within ≤0.015 mm according to GB standards, allowing for fine machining accuracy and surface roughness up to Ra ≤ 2.5 μm in single cuts. The DK7725Z can handle workpieces up to 400 mm thick and weighing as much as 400 kg, with a maximum taper angle capability of ±6° per 80 mm for detailed shaping. Powered by a 3-phase 380V/50Hz supply with a consumption of approximately 1 kW, it uses a water-based working fluid (JA-1) with filtration via filter screen to maintain cutting stability. The machine weighs about 1100 kg and measures 1420×1040×1700 mm, featuring X, Y, U, and V-axis stepper motors and a DQE-DS series CNC controller. It offers functions such as auto-centering, wire break detection, power loss memory, and auto-edge positioning, enhancing operational reliability and precision in wire EDM cutting tasks. This combination of features suits detailed, high-precision metal cutting applications in tool manufacturing and complex component fabrication.
