  • surface finish question

    I'm probably posting this in the wrong area but maybe someone can help.. What is the surface finish standard (125 or better? 32 or better?) according to ASME Y14.5-1994 when it is not stated on the blueprint

    Your customer will provide this information. If it's not on the print, then it is probably buried in a parts list, supplier quality requirements, or supplier spec. Y14.5 does not mandate a specific roughness. ASME B46.1 is the standard for surface texture. You can purchase one here:
