Rules of Thumb for surface finish equivalent of N grade and Ra values. Static mating surfaces (or datums)…. N7 = 1.6 m m (micro.m) Bearing Surfaces…. N6 = 0.8 m m (micro.m) Fine lapped surfaces…. N1 = 0.025 m m (micro.m) Surface Texture Equivalents Disclaimer: The information on this page has not been checked by an independent person.

2023年3月26日 · Surface finish is the nature of a surface as defined by the three characteristics of lay, surface roughness, and waviness. The term “surface finish” is not defined correctly and tends to be used interchangeably by product designers and engineers with surface roughness, surface texture and surface topography.

Surface finish refers to the process of altering a metal’s surface that involves removing, adding, or reshaping. It is a measure of the complete texture of a product’s surface that is defined by three characteristics of surface roughness, waviness, and lay. The surface roughness is the measure of the total spaced irregularities on the surface.
