TOPSCNC DK7740ZAC WIRE EDM MACHINE

Technical Description

The TOPSCNC DK7740ZAC Wire EDM Machine is a CNC-controlled precision wire electrical discharge machine designed for metal cutting applications. It features an X-axis travel of 15.75 inches (400 mm) and a Y-axis travel of 19.69 inches (500 mm), enabling the machining of workpieces up to 400 mm thick with a maximum table load capacity around 600 kg. The machine uses high-precision stepper motors for the X, Y, U, and V axes, allowing simultaneous 4-axis control with a minimum control increment of 0.001 mm, ensuring machining accuracy up to 0.015 mm and cutting precision as fine as 0.012 mm. The electrode wire diameter ranges from 0.15 to 0.2 mm, preferably 0.18 mm, and the wire feed speed is frequency adjustable between 1 and 11.4 m/s, supporting a maximum machining speed of ≥220 mm²/min. Surface finishes can achieve roughness levels as low as Ra ≤ 0.9 µm after multiple passes. The machine includes a 90-liter water tank with a paper filter and Italy-made pump filtration system for optimal cutting fluid management. Safety features include a closed protective cover standard. The DQE-DC-01 CNC controller offers advanced technological control, supporting taper cutting up to 60° on 100 mm thickness and complex shape machining. Power consumption is low at approximately 0.7 kW with a maximum current of 10 A on a 380 V, 3-phase, 50 Hz power supply. The overall machine weight ranges from 1800 to 3800 kg depending on configuration, with dimensions near 2100×1750×1950 mm, making the DK7740ZAC suitable for medium to large-scale precise wire EDM operations.
