TOPSCNC DK7732ZG WIRE EDM MACHINE

Technical Description

The TOPSCNC DK7732ZG Wire EDM machine features a CNC control system (DQE-DC-03) designed for high precision electrical discharge machining. It offers an X-axis travel of 12.6 inches (320 mm) and a Y-axis travel of 15.7 inches (400 mm), enabling precise machining within a compact work envelope. The robust worktable measures approximately 740 × 460 mm, supporting a maximum workpiece size of 800 × 500 mm and a weight capacity of up to 600 kg. The machine handles workpiece thicknesses up to 400 mm with a maximum taper angle capability of ±6° over 80 mm. It uses fine molybdenum wire from 0.15 to 0.20 mm diameter (recommended 0.18 mm) for cutting, achieving machining precision within ±0.015 mm and surface finishes as tight as Ra ≤2.5 μm. The feeding speed is adjustable up to 11.4 m/min, optimizing cutting speed without compromising accuracy. The DK7732ZG incorporates four-axis stepper motor drives (X, Y, U, V) for simultaneous multi-axis control, ensuring complex and precise contouring. Its 55-liter water tank with filtration systems maintains stable dielectric conditions during processing. Power consumption is rated around 1 kW under a 3-phase 380V supply. Weighing approximately 1300 kg with a footprint near 1550 × 1170 × 1700 mm, this machine is suitable for various metal cutting applications requiring fine detail and high tolerance. The machine also includes built-in protections such as wire-burning prevention and stable power discharge control to enhance operational reliability and surface finish quality. It is engineered for ease of operation and includes after-sales support, with availability for overseas servicing.
