Productive seal fin machining
Seal fins, air seals or labyrinth seals as they are also called, are key features for the functionality of gas turbine engines and are commonly found on turbine wheels.
For productive seal fin machining we recommend:
- Scoop Turning
- Trochoidal turning
Trochoidal turning method
By choosing trochoidal turning over the more traditional ramping method, productivity can be doubled with improved security and tool life.
Trochoidal turning uses the front edge line and continuously changes the contact point between insert and material.
