The CHMER RQ4025L Wire EDM Machine is a high-precision CNC-controlled wire-cut electrical discharge machine designed for demanding machining applications. Featuring a robust gantry-style structure with a fixed table, the RQ4025L delivers exceptional rigidity and accuracy, making it ideal for intricate and heavy-duty workpieces. The machine offers an X-axis travel of 15.75 inches (400 mm) and a Y-axis travel of 9.84 inches (250 mm), with a Z-axis travel of 200 mm, enabling versatile machining capabilities. The U and V axes each provide 60 mm of travel, supporting complex taper and contour cutting. The RQ4025L is equipped with linear motor drive technology on the X and Y axes, ensuring backlash-free movement, precise positioning, and long-term reliability. The machine can handle workpieces up to 750 x 450 x 200 mm in size and a maximum weight of 550 kg, making it suitable for a wide range of industrial applications. Advanced features include an auto wire threading (AWT) system for efficient setup and reduced downtime, a high-performance i8+ power supply for stable cutting, and a built-in chiller for precise temperature control. The RQ4025L also incorporates thermal compensation and automatic conductivity and fluid temperature control for consistent machining accuracy. With a maximum wire feed rate of 300 mm/sec and a wire diameter range of 0.15–0.3 mm (0.1 mm optional), the machine supports fine and high-speed cutting. The CNC control system provides intuitive operation and programming, ensuring ease of use and high productivity.
