The TOPSCNC DK7763ZAB is a precision wire EDM (Electrical Discharge Machine) designed for high-accuracy cutting of complex geometries in hardened metals and exotic materials. This CNC-controlled system features an X-axis travel of 24.8 inches and Y-axis travel of 31.5 inches, providing substantial working capacity for medium to large workpieces. The machine utilizes a thin metal wire electrode with deionized water as the working medium to achieve precise cuts through tough materials without mechanical stress. The DK7763ZAB employs advanced CNC technology for automated multi-axis control, enabling sophisticated taper cutting and angular operations. The system incorporates precision linear guideways and a robust control platform that supports CAD integration for seamless design-to-production workflows. Wire diameter capabilities typically range from 0.10mm to 0.25mm, allowing operators to select wire sizes based on required precision and cutting speed demands. Key performance characteristics include cutting accuracy down to ±0.015mm on straight cuts and enhanced surface finish capabilities with Ra values as low as 1.0-1.2 micrometers for optimal dimensional precision. The machine operates on standard three-phase 380V/50Hz power supply and incorporates a comprehensive filtration system with 0.005mm filter media to maintain dielectric fluid purity, essential for consistent cutting performance and extended consumable life. This wire EDM machine is ideal for tool and die manufacturing, aerospace components, medical devices, and precision engineering applications requiring superior edge quality and dimensional consistency without thermal distortion.
