Summary

The Starrag NB 151 is a dedicated 5-axis machining center engineered for efficient roughing and finishing of blisks, impellers, diffusors, and nozzle guide vanes. Designed to address the specific technical challenges of thin, unstable airfoils and multi-blade parts, it provides direct spindle expansion compensation and adaptive machining strategies for consistent accuracy in demanding aerospace and energy component manufacturing.

Key Capabilities

• Simultaneous 5-axis machining for complex blisk and integrally bladed rotor geometries
• Direct compensation of spindle expansion due to thermal drift or centrifugal forces
• Adaptive machining for precision-forged and friction welded blade edges and snubbers
• On-machine workpiece and tool measurement with Siemens CNC control integration
• Flexible tool magazine with up to 320 tool capacity and HSK-A63 taper support
• Through-spindle and external cooling, including CO2 capability
• Custom clamping solutions for specialized blade and blisk geometries
