The CHMER RQ5030L is a precision wire electrical discharge machining (EDM) system engineered for high-accuracy cutting of complex geometries in hard materials. This gantry-type machine features X-axis travel of 500mm (19.69 inches) and Y-axis travel of 300mm (11.81 inches), with Z-axis capability of 200mm, accommodating workpieces up to 850x500mm and weighing up to 600kg. The machine incorporates CHMER's proprietary linear motor technology on X and Y axes, delivering rapid servo control with enhanced discharge gap sensitivity that improves cutting speed by 8-10%. It operates with wire diameters ranging from 0.15mm to 0.3mm and supports taper angles up to ±14.5°/80mm for angled cuts. The CNC control system provides 0.5µm resolution positioning on glass scales (standard on GX series and above), enabling micron-level precision for aerospace, automotive, and medical manufacturing applications. Wire tension adjustment spans 300-2500 grams for optimal performance across varying material thicknesses. The machine dimensions measure 2500x2650x2250mm (WxDxH) with a total weight of 3000kg. An optional automatic wire tensioning (AWT) system and automatic rise-and-fall front door enhance operational efficiency. The RQ5030L integrates advanced dielectric fluid circulation and filtering systems for superior surface finish and extended tool life, making it ideal for precision manufacturing requiring tight tolerances and excellent edge quality.
