aluminum surface smoothness comparison?

Mar 28, 2005 3 Replies

Does anyone know a website that shows photographs of turned aluminum along with specifications?



I have a requirement for a cylindrical part but I don't know how to call-out surface smoothness. I'm only interested in a mechanical treatment. I want a "shiny" finish but not a diamond-turned mirror finish. Is "shiny" an appropriate call-out to a machinist?
