LX 251
Machining of all types of blade with one jig thanks to an innovative and flexible fixture concept
The optimisation of unit costs for ready-to-install blades thanks to an integral machining concept for pre and postprocessing in a clamping position
The highest levels of process reliability and efficiency, thanks to individual application-orientated technology services
Turbine Blade machining center
The LX series was specifically designed for the high-precision, efficient five-axis machining of turbine blades. This ultra-modern machining platform is the result of decades of experience in the development of machine tools, CAM systems and special tools combined with our in-house expertise in the prototype and series production of turbine blades.

The special work-piece geometries create specific demands on the clamping fixtures. Starrag has in-house specialists who develop individual clamping concepts to meet the specific requirement of blade machining. Starrag offers the following advantages:
- A single adapter design solution for all LX machine sizes using vices (at the hub) and hydraulic clamping jaws (at the shroud)
- Clamping jaws can be implemented in a flexible way both for raw and for premachined surfaces
- Distortion free machining due to flexible changeover between centrically and floating clamping
- Starrag solutions enable distortion and indentation free clamping on freeform surfaces for the manufacturing of unstable blades
- Geometric deviations between multiple fixtures can be stored in the control system. Measuring of blanks can therefore often be eliminated
One key factor to lowest tool cost and highest productivity is the right process cooling. The LX machine series offers all state-ofthe- art through-spindle cooling options:
- High pressure coolant (water-based or oil)
- Through spindle air
- Aerosol (minimum quantity lubrication)
- CO2 cryogenic cooling through the spindle
- Aerosol plus CO2 through spindle
Of course external cooling with coolant or CO2 is possible too. With these options, breakthroughs in tool life can be achieved, leading to the lowest overall cost.
Process analyses and stability evaluations can be made easily with integrated sensors and evaluation routines. Collision damage is significantly reduced thanks to rapid crash detection and machine stop. This is an excellent addition to Starrag’s simulation solutions to avoid expensive machine downtime. The balancing quality of all tools and the state of the spindle bearings are automatically monitored.
