Turbine shaft machining
During 2023, we worked on a turbine shaft at the Baigts Castetarbe Hydroelectric Power Plant in France for our customer EDF.
- Machining (delardage) of the shaft of 10mm at minimum radius over a length of 450mm
- Welding of 2 half shells (machined in our workshop) on the tree by an external company
- Machining of welded half-shells to obtain the final diameter Ø200
- Diameter tolerance Ø200: 0.1 mm
- Conicity: (0; + 0.1 mm)
- Coaxiality: (0; + 0.2 mm)
- Surface condition: Ra 1.6 (obtained: 0.3/ 0.4)
Our intervention took place in several stages:
- Step 1: Analysis of the subject in our Design Office (feasibility, 3D modeling of the tree, implementation of our machine in the 3D work environment).
- Step 2: Carrying out pre-work checks (Laser Tracker) by an external company to define the origins and create a reference.
- Step 3: Installation of our machine on site and machining.
- Step 4: Soldering half shells.
- Step 5: Realization of controls (Laser Tracker) by an external company in order to recover the repository and adjust the machine.
- Step 6: Installation of our machine on site and finishing machining.
- Step 7: Completion of after-work checks (Laser Tracker) by an external company.
