EASTAR CW-70 WIRE EDM MACHINE

Technical Description

The EASTAR CW-70 Wire EDM Machine is a high-precision CNC-controlled electrical discharge machining system designed for accurate and efficient cutting of conductive materials. Featuring a robust submerged-type construction, the CW-70 delivers stable machining performance ideal for aerospace, automotive, and high-tech manufacturing applications. The machine offers a generous travel distance of 31.5 inches (800 mm) on the X-axis, 19.7 inches (500 mm) on the Y-axis, and 11.8 inches (300 mm) on the Z-axis, enabling the processing of large and complex workpieces with consistent accuracy. Its CNC control system ensures precise axis movement and reliable repeatability, supporting both semi-automatic and fully automatic operation modes. The CW-70 is equipped with advanced features such as automatic wire vertical alignment and water conductivity control, which enhance cutting stability and surface finish quality. It achieves a cutting accuracy of ±3.5 µm and can produce surface finishes as fine as 0.6 Ra (with an optional 0.2 Ra finish available). The machine utilizes brass wire electrodes with diameters of 0.20, 0.25, or 0.30 mm, supporting high cutting efficiency up to 200 mm² per minute. Designed for versatility, the CW-70 is suitable for a wide range of conductive materials, including hardened steels, titanium, and exotic alloys. Its user-friendly interface and automated functions streamline setup and operation, reducing downtime and increasing productivity. The EASTAR CW-70 Wire EDM Machine is a reliable solution for demanding precision machining requirements in modern industrial environments.
