Blisk

The blick starts as raw material, a forged hub, or sometimes as individual airfoils.

The challenge
The integrity of the raw material is critical to the final product. The material, composition, and purity must be checked. When it comes to forgings, it is crucial to measure the material shape to ensure that it complies with the required specifications.

Our solution

• ZEISS industrial microscopy solutions are the perfect complement to the production of raw materials, checking their metallurgical composition.
• ZEISS ScanBox offers full-field measurement and forging inspection.

Creating the interface and weight relief features for the compressor blisk is a high-accuracy activity.

The challenge
It can be challenging to measure precision bores and weight relief grooves accurately and promptly due to their limited accessibility.

Our solution

• For high accuracy needs, the ZEISS PRISMO Family is perfect. The integrated rotary table reduces measuring cycle times significantly.
  
• For the surface finish, ZEISS ROTOS sensors can accurately determine roughness.

Adding pre-forged blades to the disc hub body using mechanical rubbing is a common technique with specific quality requirements.

The challenge
In the inherent nature of a welding process, excess material is at the position between the root of the airfoil as it connects to the disc, necessitating further machining.

Our solution

• The ATOS ScanBox ensures a flawless blend and transition between the airfoil and the annulus surface on the blisk is to measure the data in 3D and pass data to third-party adaptive machining processes.

Whether full machining from stock material or blending linear friction-welded airfoil, airfoil machining is a time-consuming process that tremendously impacts the engine's performance.

The challenge
Airfoil geometries are becoming increasingly complex, with more twisted and sharper edges. Factory floor space is at a premium, and production rates are high, demanding faster measurement times.s.

Our solution

• ZEISS solutions are fast, accurate, optical, and tactile, and they are compact to meet our customers' demands. Whether the solution is tactile scanning or 3D data capture, the answer is a ZEISS solution.
  

Regulatory and original equipment manufacturers (OEM) requirements like AS9102 or AS13003 are necessary, stringent, and comprehensive to fulfill.

The challenge
Extensive validation requirements on a blisk with complementary solutions are needed to fulfill all requirements.

Our solution

• High-accuracy tactile, optical, and microscopy solutions fulfill thousands of characteristics that are necessary to validate.
• ZEISS Quality Suite helps compile results effectively.
• Specific software like ZEISS INSPECT Airfoil efficiently qualifies every characteristic on part drawings or other standards.
