Tīmeklis2024. gada 14. jūl. · A #4 finish is a straight-grained finish commonly thought of as ‘brushed’ finish, as are #3 and #6 finishes. 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 … Tīmeklis2015. gada 7. apr. · Miles Free. Director of Industry Research and Technology, PMPA. Ra measures the average length between the peaks and valleys and the deviation from the mean line on the entire surface within the sampling length. Rz measures the vertical distance from the highest peak to the lowest valley within five sampling lengths and …
