The TOPSCNC DK7740ZB Wire EDM Machine is a precision CNC-controlled electro-discharge machining system designed for accurate and efficient cutting of complex shapes in conductive materials. With a travel distance of 15.75 inches (400 mm) along the X-axis and 19.69 inches (500 mm) along the Y-axis, this machine provides a generous work envelope suitable for a wide range of industrial applications. The CNC control system ensures high repeatability and accuracy, enabling intricate contours and tight tolerances to be achieved consistently. The machine utilizes a thin wire electrode, typically ranging from 0.10 to 0.30 mm in diameter, which is guided precisely through the workpiece using advanced linear guides and servo motors. Cutting is performed with deionized water as the dielectric fluid, ensuring clean and burr-free results. The DK7740ZB supports multi-axis control, allowing for taper and angled cuts with high surface finish quality. Its robust construction and stable machine bed minimize vibration, enhancing machining accuracy and reliability. The system is engineered for ease of operation, maintenance, and integration into modern production environments. Ideal for tool and die making, mold manufacturing, and precision component fabrication, the TOPSCNC DK7740ZB delivers dependable performance, excellent cut quality, and flexibility for diverse machining requirements.
