CHMER RX853S WIRE EDM MACHINES

Technical Description

The CHMER RX853S is a precision submerged wire-cut EDM machine engineered for high-accuracy machining of complex geometries in hardened materials. This compact model features X-axis travel of 31.5 inches (800mm) and Y-axis travel of 19.7 inches (500mm), with an 11.8-inch (300mm) Z-axis stroke, accommodating workpieces up to 1210x800x295mm and weighing up to 2000kg. The machine incorporates U, V, and Z auxiliary axes with 150mm travel each, enabling multi-directional angled cutting capabilities with a taper angle range of ±21°/140mm using wide-angled nozzles. The submerged machining system provides superior surface finish and extended wire life by maintaining the cutting wire in dielectric fluid throughout the operation. The RX853S utilizes CHMER's proprietary CNC control system with integrated PLC electronics for seamless operation and precise part programming. Wire feed rates reach 300mm/minute with tension control between 300-2500 gf, accommodating wire diameters from 0.15mm to 0.3mm for intricate detail work. The machine measures 3150x3500x2350mm externally and weighs approximately 5535kg, requiring a 2700x3000x2200mm floor space. The coolant system features a 650-liter tank capacity with paper filtration to maintain dielectric quality during extended production runs. Standard construction includes servo drive systems for both primary and auxiliary axes, ensuring consistent cutting velocity and dimensional accuracy. The RX853S comes equipped with 12-month warranties on electrical and mechanical components, making it suitable for tool and die shops, aerospace, and precision manufacturing applications.
