What is the surface roughness value? How to select the surface roughness value for different part surfaces?

01 Concept of surface roughness Surface roughness refers to the micro geometric form error composed of small spacing and small peaks and valleys on the machined surface, which can be understood as the unevenness of small spacing and small peaks and valleys during product processing. The smaller the micro geometric error of the machined surface … Continue reading What is the surface roughness value? How to select the surface roughness value for different part surfaces?
