Dear experts: Is it necessary to machine the inner surface of the flange for tower robot manholes, and are there any relevant standard requirements?

If the surface finish of the machine parts in our unit is good, no further processing is needed; otherwise, manual processing is required

Generally, no machining is required, but the welds have good shape, which does not hinder access for people

The surface should be slightly treated to remove burrs and similar issues, so as to avoid injuring people entering and leaving.

At the very least, the surface should be visibly smooth, even, and aesthetically pleasing.

The drawings should have default surface finish requirements

The standard does not impose such a requirement; it depends on the surfacing method and the quality of the formed surface

The corrosion-resistant layer has high requirements for surface finish and must be processed! Or use a liner format!
