Very similar work involving the machining of a groove for sealing of vanes.
However, the main difference is the diameter of the flow path of the water turbine.
For this reason, we used different machines to achieve the same goal in both cases.
|Number and type of turbines||2 x Kaplan||3 x Kaplan|
|Machining diameter [mm]||4000||5000|
|Type of machining||Turning||Circumferential milling|
