Purpose:
Fitting silver navigation.
2. Requires
position Tolerance: The copper cathodes compared to navigate high pin insertion hole.
- Dimensional tolerances: High to silver when inserted into the guide is not too tight or too loose. And when fitted to ensure the residuals to be mounted in silver navigation uncertain. But the surplus is too large to avoid damaging the silver navigation.
- For example: Choose silver navigation O30 (mm) accuracy level domain 5 P tolerance distribution, deduced true size of the hole is 29 967 ÷ 29 978.
3. Processing method:
Drill + reamer.
