Tīmeklis5 ROUGHNESS MEASUREMENTS OF STAINLESS STEEL SURFACES Summary Although Ra values are commonly used to describe surfaces, the limits of this indicator should not be forgotten. Also the notation is important: “Ra ≤ 0.5 µm”, for instance, does not have the same meaning as “Ra max 0.5 µm”.Surface designations such as “2B” TīmeklisRa μm AA – CLA μinch Conventional symbols Surface description 0.025 0.05 1 2 Super inishing Burnishing diamond paste 0.1 4 Lapped, extremely ine inish, perfectly smooth 0.2 8 Lapped for seal joints 0.4 16 Ground, EDM 0.8 32 Machined, extremely ine inish 1.6 63 Machined, very smooth 3.2 125 Machined, smooth 6.3 250

TīmeklisMachining of gasket faces of flanges to a smooth finish of Ra = 3.2 - 6.3 micrometer. (= 125 - 250 microinches AARH) AARH stands for Arithmetic Average Roughness Height. It is used to measure the roughness (rather smoothness) of surfaces. 125 AARH means 125 micro inches will be the average height of the ups and downs of the surface. TīmeklisD.h. in diesem Fall entspricht Ra 6,3 einem Rz 22 (Pi mal Daumen). Da mir allerdings mal beigebracht wurde, das ich mich an den Vorzugsreihen zu orientieren habe, würde ich hier also zu einem Rz 25 raten.
