TOPSCNC DK7732ZAC WIRE EDM MACHINE

Technical Description

The TOPSCNC DK7732ZAC Wire EDM Machine is a high-precision CNC wire electrical discharge machining system designed for complex and accurate cutting tasks. It features X- and Y-axis travels of 12.6 inches (320 mm) and 15.7 inches (400 mm) respectively, with a worktable size of 440 × 680 mm and supports a maximum workpiece weight of up to 600 kg and thickness of 400 mm. The machine employs a 4-axis simultaneous control system (X, Y, U, V axes) driven by stepper motors, enabling intricate taper cuts with a maximum taper angle of ±6° over 80 mm length. It uses molybdenum wire with recommended diameters of 0.15 to 0.20 mm, running at adjustable wire feed speeds of 1 to 11.4 m/s. Precision machining is guaranteed with an accuracy of ≤0.015 mm and surface roughness achievable at one-time cut Ra ≤ 2.5 μm, improving with multiple cutting passes. The control system is powered by DQE-DC-01 CNC controller, supporting advanced functions such as taper cutting, auto-centering, and power failure memory. The machine operates on 3-phase 380V/50Hz power with a rated power consumption around 1 kW. The water tank capacity is 55 liters, equipped with filtration for stable dielectric fluid circulation. The DK7732ZAC is constructed for durability and ease of operation, weighing approximately 1300 kg, with machine dimensions of 1550 × 1170 × 1700 mm. It offers features suited for robust industrial EDM applications with precision, efficiency, and versatility.
