The TOPSCNC DK7732ZA is a precision CNC wire electrical discharge machining (EDM) system engineered for high-accuracy metal cutting applications. This machine features X-axis travel of 12.6 inches (320mm) and Y-axis travel of 15.7 inches (400mm), accommodating workpieces up to 600kg with maximum thickness of 400mm. The work table measures 440x680mm, providing ample surface area for complex component machining. Equipped with CNC control via the DQE-DC-01 system, the DK7732ZA delivers machining precision of ±0.015mm, ensuring reliable repeatability for demanding industrial applications. The machine achieves exceptional surface finish quality, with Ra≤2.3μm in single-pass cuts and improved results with multiple passes. Maximum cutting current reaches 10-15A, delivering cutting speeds up to 350mm²/min under optimal conditions. The machine utilizes molybdenum wire electrodes (Φ0.12-0.20mm diameter) with minimal wear characteristics—approximately 0.01mm after 500,000mm² of cutting. It incorporates a 60L working tank with 0.005mm changeable filtration, maintaining dielectric fluid quality for consistent performance. The four-axis stepper motor drive system enables simultaneous X, Y, U, V axis control, supporting taper angles up to ±6°/80mm. Built with PC/104 industrial-grade motherboard architecture, the DK7732ZA features double-impulse circuitry and electrolytic protection during operation. Housed in a 1640x1250x1920mm cabinet weighing 1200kg, this system operates on single-phase 380V/50Hz power with 1kVA rated consumption.
