KINGRED DK7750 WIRE EDM MACHINE

Technical Description

The KINGRED DK7750 Wire EDM Machine is a high-performance CNC-controlled electrical discharge machining system designed for precision cutting of conductive materials. Featuring an X-axis travel of 19.69 inches (500 mm) and a Y-axis travel of 24.80 inches (630 mm), this machine offers robust worktable movement suitable for a wide range of industrial applications, including mold making and accurate component manufacturing. The DK7750 utilizes molybdenum wire as the electrode, providing a cost-effective alternative to brass wire EDM systems while maintaining high cutting efficiency and accuracy. It is equipped with advanced KDXP (AutoCUT) CAD/CAM software running on a Windows XP operating system, ensuring ease of use, programming, and maintenance. The machine’s digitalized electrical circuits, controlled by an inverter, enable smooth wire feeding and adjustable feed speeds—low speed for wire loading and high speed for machining. Its construction incorporates resin sand casting technology and double high-temperature tempering treatment, minimizing internal stress and reducing the risk of deformation for enhanced long-term reliability. The DK7750 delivers a maximum cutting thickness of up to 500 mm and achieves a cutting accuracy of ±0.015 mm, making it ideal for high-precision tasks. Additional features include a central lubrication system, modular internal wiring for reduced failure rates, and a range of automated functions such as short-circuit and wire-break handling, auto-edge positioning, auto-centering, and power-loss memory. The machine supports various machining modes and offers optional taper cutting capabilities, ensuring versatility for complex geometries. With its combination of precision, reliability, and user-friendly controls, the KINGRED DK7750 is a dependable solution for demanding wire EDM applications.
