• 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.
