Section IV – Static O-Ring Sealing

If the surface is produced by turning the part on a lathe, or by some other method that produces scratches and ridges that follow the direction of the groove, a very rough surface will still seal effectively. Some methods such as end milling or routing, however, …

Roughness measurements of stainless steel surfaces

Surface roughness is a measure of the texture of a surface. It is quantified by the vertical deviations of a real surface from its ideal form. If these deviations are great, the surface is rough, if they are small, the surface is smooth. Roughness is typically considered to be the high-frequency, short-wavelength component of a measured surface.

Flatness Tolerance in GD&T - Metal Cutting Corporation

Second, measuring the surface flatness of the cut end on very small parts — such as tubes with a diameter of 0.040″ (1.016 mm) and other tiny parts we typically produce here at Metal Cutting — is virtually impossible. Third, the flatness of a part can't be measured by placing it on a table and running a height gage over the part.
