IN-SITU MECHANICAL PROCESSING MACHINE
This tooling enables hybrid coupler tracks to be machined directly inside the Tokamak WEST chamber.
IN-SITU MECHANICAL PROCESSING MACHINE
The mission's challenge
The machining of dual-material components in situ, in a confined environment, without lubrication, and with high precision required a miniaturized design combining lightness, compactness, and rigidity.
Specificity
Multi-material machining with cutting parameters specific to each material.Technical characteristics
| Depth of cut | ≤0.1 mm |
| Surface finish after machining | Ra ≤ 6.4 |
| Environment | confined chamber |
| Operational | ambient |
| Temperature | 22 ± 3°C |
Operational characteristics
The operation to be performed is the re-machining of the external tracks of the LH2 coupler to remove 2.1 to 5 mm of material from the end tracks of the coupler.
