Influence of grinding parameters on Inconel 625 surface

Jul 01, 2020 Surface integrity was assessed in terms of surface roughness (Ra and Rz), observations of SEM images and microhardness. The results showed that Inconel 625 is highly susceptible to work hardening during grinding. The grinding wheel speed (v s) was the parameter of greatest effect and the best results were obtained when v s =15 m/s

Beyond Ra: Why Surface Finish Matters in Seal Performance

Feb 07, 2019 Simply understanding a mating surface’s R a, or roughness average value, is not enough to properly specify the surface finish because it is entirely possible to have very different surface textures with similar R a values, and those variances can greatly affect seal performance

Surface Roughness vs Surface Finish | RA & RMS | Astro Pak

Jul 14, 2020 A standard #4 finish could be about 0.8 (32) Ra, while a #4 Dairy or Sanitary finish have an roughness average between 0.3 (12) Ra and 0.4 (16) Ra. Two other finishes; #7 and #8 are buffed. The surface of #8 is very nearly flawless. The Ra on a #8 finish would be 0.025 (1) Ra
