Prevent Turbine Failures Before They Start
Optical Break Edge and Cooling Hole Inspection

How reliable are your turbine components under extreme conditions?

Aircraft turbines operate under extreme thermal and mechanical stress. Even the smallest geometric deviations can affect performance, efficiency, and component lifetime.

Break edges and cooling holes play a crucial role.

Improper edge finishing can lead to burrs, cracks, and premature material failure, while deviations in cooling hole geometry can compromise the thermal protection of turbine blades operating at temperatures of up to 2,000 °C.

For manufacturers, this raises a key challenge:

How do you inspect both edge quality and complex cooling hole geometries quickly, reliably, and directly in production?

Our Solution: Optical 3D Metrology for Edge Break Inspection

Burrs and improperly machined edges created during turning, milling, or drilling can quickly lead to material fractures, crack initiation, or premature component failure.

For safety-critical aerospace components such as:

fan blades
compressor disks
blisks
turbine housings

precise edge finishing and reliable inspection are essential.

Optical 3D metrology enables fast and repeatable inspection of edge geometry, capturing even the smallest deviations that could compromise component integrity.

With Bruker Alicona devices, manufacturers can measure break edges with tolerances in the single-digit micrometer range, ensuring reliable quality control for critical turbine components.

Key Benefits

Non-contact measurement of break edges and burrs
Measure break edges with tolerances in the single-digit µm range
High-resolution 3D edge geometry analysis
Repeatable measurements for reliable production control

In turbine manufacturing, however, edges are only one part of the equation. Another critical feature that directly affects performance and thermal protection are cooling holes.

Tiny Features, Critical Impact: Cooling Hole Measurement

Cooling holes may be small — but they are critical for turbine performance.

They protect turbine blades from extreme temperatures and ensure reliable operation even under extreme conditions of up to 2,000 °C.

With up to 500 cooling holes per blade, ensuring every single one meets exact specifications is a major challenge.

Optical 3D metrology enables fast and automated inspection of these complex geometries.

Measure critical parameters such as:

diameter
position
angle
cylindrical length
diffuser geometry

with high-resolution, non-contact measurement technology.
