✔ You need to check that the hole has the correct tolerance

✔ You need to check the surface finish

✔ You need to check the hole countersink

✔ You need to check exit and entering of the hole

Our assembly process settles for the perfect hole and total control of end results.

Thus, inspecting the quality of the hole according to the requirements (correct tolerance, diameter, roundness, perpendicularity, surface finish, etc.) is an important step in the whole aerospace assembly process.

Have total control of end results by checking and assuring the quality of the holes. This is crucial after all the efforts you spent in making perfect holes.
