The HURON KX Large Series is a premium line of 5-axis bridge-type double column machining centers, built to deliver exceptional rigidity, precision, and power for the most demanding machining operations. Designed with a fixed-portal architecture and modular flexibility, the KX Large Series supports full 5-sided and 5-axis simultaneous machining of complex parts in hard materials, making it the ideal solution for large aerospace components, energy sector parts, molds, dies, and precision mechanical engineering. With working capacities up to 20,000 kg and machining volumes of 4,080 × 2,180 × 1,550 mm, this series offers high structural integrity, advanced thermal compensation, and full contouring accuracy even under heavy cutting forces.
Built for high performance in both roughing and finishing, the KX Large machines integrate a fixed gantry structure with mobile tables, slides, and saddles engineered from cast iron, welded steel, or concrete—depending on the model—to absorb vibrations and dynamic loads. Linear axes are supported by recirculating roller bearings with absolute measurement scales, while AC servo motors drive precision ball screws to achieve rapid feedrates of up to 40 m/min. The rotary B and C axes are driven by backlash-free torque motors with angular encoders for high-speed positioning, allowing complex 4- and 5-axis interpolation at full power. The integrated electrospindle ensures high torque, vibration monitoring, and long tool reach, even for deep pocket machining. Additionally, ergonomic features like wide table access, external tool magazines, chip conveyors, and a fully enclosed splash-proof environment enhance operator safety and usability. The KX Large Series is also CNC-equipped with a high-memory control system, graphical simulation, and interactive programming for seamless operation and full 5-axis machining control.
