TOPSCNC DK7732ZF WIRE EDM MACHINES

Technical Description

The TOPSCNC DK7732ZF is a precision CNC wire electrical discharge machining (EDM) system engineered for high-accuracy metal cutting applications. This machine features a worktable size of 440×680mm with X-axis and Y-axis travel of 320×400mm respectively, accommodating workpieces up to 600kg in weight and 400mm in thickness. The system operates on 3N-380V/50Hz power supply with 1kW power consumption and delivers exceptional machining precision of ±0.015mm with surface roughness maintained at Ra≤2.5μm. Equipped with four-axis simultaneous control (X, Y, U, V) stepper motors, the machine achieves a minimum control pace of 0.001mm for intricate detail work. The wire diameter ranges from φ0.15–φ0.20mm (recommended φ0.18mm), with adjustable feeding speeds between 1–11.4m/sec and machining speeds exceeding 200mm²/min. The machine supports maximum taper angles of ±6°/80mm, enabling angled cutting operations. The DK7732ZF incorporates advanced EDM technology with electronic Z-axis control using slide guides and features a 55L working fluid tank with filter screen filtration for optimal dielectric fluid management. Its robust construction weighs 1,480kg with dimensions of 1,550×1,170×1,900mm, utilizing the DQE-DS-01/02/03 controller for reliable operation. With maximum working current of 12A and PLC-controlled automation, this machine delivers consistent, repeatable results suitable for die-making, prototype development, and precision component manufacturing across diverse industrial sectors.
