NB 151

Blisk machining center


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.

Key benefits
Dedicated kinematic concept for efficient Blisk roughing o-finishing.
A single adapter design solution is used for all NB machine sizes.
Expansion of the spindle through thermal drift or centrifugal forces can constantly be measured and compensated for by direct measurement.
The effects of machine displacements due to thermal conditions can be corrected directly on the workpiece through an automated process before machining.
