The SANXING DK77100A is a precision wire electrical discharge machine (EDM) engineered for high-accuracy cutting and complex geometries. Featuring CNC control, this machine delivers automated machining capabilities with user-friendly programming interfaces. The substantial X-axis travel of 70.7 inches combined with Y-axis travel of 39.3 inches accommodates large workpieces, making it suitable for industrial applications requiring extended cutting ranges. The wire EDM technology utilizes a thin wire electrode to perform electrical discharges, enabling extremely precise cuts with minimal material waste and no thermal distortion to surrounding material. This method is ideal for machining hardened steels, exotic alloys, and complex shapes that conventional cutting methods cannot achieve. The CNC control system ensures repeatability and consistency across production runs, reducing manual intervention and human error. Wire EDM machines like the DK77100A excel in applications including die and mold manufacturing, aerospace component production, and precision tool fabrication. The technology operates through submerged machining conditions that dissipate heat and flush away debris, resulting in superior surface finish quality typically ranging from 0.3–0.4 Ra. The machine's extensive travel dimensions combined with robust servo control systems and digital spark management provide optimal balance between cutting speed and precision. Advanced features typically include automatic wire threading, real-time monitoring systems, and integrated filtration for consistent dielectric fluid quality, ensuring reliable long-term operation and minimal downtime in production environments.
