The KENT USA WSI-640 is a precision CNC wire EDM machine designed for high structural rigidity, featuring a maximum travel of 23.6 inches (X-axis), 17.7 inches (Y-axis), and 13.7 inches (Z-axis). It includes automatic threading for efficient wire threading and operates in a submerged cutting environment, which reduces noise and wire breakage while improving taper cutting performance. The machine weighs 7,716 lbs and measures 141.7”W x 102.4”D x 90”H. Its structure is CAE-analyzed, with U, V, and Z axes positioned on the upper column for enhanced spindle rigidity and precision. Equipped with a magnet power clutch wire-receiving system, it uses Panasonic AC servo motors for reliable wire feed control. The WSI-640 supports taper angles up to ±22.5° and a maximum axes load of 22 lbs, with a large 248-gallon water tank ensuring stable temperature control during operation. Additional features include wire tension stability via a permanent generator control system and dual water nozzles with diameter guides for optimal cooling and flushing. This model is suited for machining complex, precise parts with minimal finishing and is backed by a 15-month warranty from Kent USA. Ideal for tooling, die making, and other high-precision industries, the WSI-640 combines robust mechanical design with advanced CNC control for consistent, accurate wire EDM cutting.
