WebJul 14, 2024 · 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 … WebThe surface roughness established by the calculation is thereby less vulnerable to extreme values than the roughness depth. A conversion of Rz to Ra and the reverse is not possible as 1:1 scale. However, a conversion interval that contains all possible values can be specified. The rule of thumb that repeatedly emerges for converting Rz = Ra*7 ...
