No matter if it is called a «Blisk» (bladed disk) or an «IBR» (integrally bladed rotor), no matter if it is single stage or multi stage, Starrag’s dedicated machine concept of the NB series provides the best solution for efficiently machining these parts. Blisks made from Titanium, Nickel-based superalloys and the Blisks made of blade steels for stationary gas turbines triggered the development of the NB series. For all the necessary manufacturing operations Starrag provides the benchmark: Efficient roughing for Blisks machined from solid, adaptive machining for friction welded Blisks, high dynamic finishing of the airfoils in point contact. Shortest cycle times and zero scrap rate production are achievable on the Starrag NB series. The NB series is based on the very successful Starrag LX series. Construction principle Minimized and balanced movement of the masses Short distribution of forces increases rigidity, leading to stable ratios during the machining process. These factors have been proven in real-time simulation during the machine development phase All base frame components are designed using FEM analysis for maximum rigidity" Highly dynamic rotary axes The rotary axes are directly driven by state-of-the-art torque motors Guarantees the most precise positioning High torque even at low speed Highest possible rigidity for maximum dynamics Power transmission free of backlash and extended service intervals No mechanical component wear Driven tip station with controllable torque
