Manufacturing blisk rotors in a single clamping operation

Starrag rounds off its blisk machining range with the Starrag NB 151

Machining blisks and impellers rapidly and reliably in a single step saves both time and money. Thanks to the five-axis Starrag NB 151, which has been specially designed for such machining processes, users from the aviation, aerospace and energy sectors can benefit from these advantages.

With its NB range, Starrag is developing five-axis machining centres designed especially for manufacturing titanium, nickel-based alloy and blade-steel blisks and impellers for stationary gas turbines. At the beginning of 2019, the machine tool manufacturer released the NB 151 as a smaller version of the larger machines in the range, the Starrag NB 351 and NB 251. The NB 151 is designed to manufacture workpieces up to 600 mm in diameter, up to 290 mm in length and up to 300 kg in weight.
