TOPSCNC DK7750ZG WIRE EDM MACHINE

Technical Description

The TOPSCNC DK7750ZG Wire EDM machine is a high-precision CNC wire electrical discharge machine designed for industrial processing with an X-axis travel of 19.69 inches (500 mm) and a Y-axis travel of 24.80 inches (630 mm). It features a CNC control system (DQE-DC-03) optimized for stable and precise machining with a cutting accuracy of up to 0.01 mm. The working table measures 1020 × 640 mm and supports a maximum workpiece weight of 1000 to 1600 kg with a maximum thickness capability around 300 to 600 mm depending on specific models and configurations. The DK7750ZG delivers cutting speeds typically around 200 to 300 mm² per minute and surface roughness as fine as Ra ≤ 1.0 μm after multiple cuts, ensuring excellent surface finishes for complex and delicate components. It employs advanced features such as servo motor drives, double-impulse and multiple-circuit electrolytic protection, high-speed sampling, and precise power discharge control to enhance cutting quality and efficiency. Machine dimensions approximate 2210 × 1650 × 2250 mm with a weight near 2100 to 3200 kg. The machine operates on 3N-380V/50Hz power with a rated power of about 1 to 1.5 kW. It supports molybdenum wire diameters from 0.12 to 0.20 mm and includes filtration systems and a working tank capacity near 60 liters for optimal operation. This model is backed by one-year warranty with available overseas service support.
