WebApr 25, 2024 · Estimating Ra from Rz While Ra smooths all measurements into one average and Rz averages only the greatest deviations, there isn't just one simple way to derive Ra from Rz. Rather, general estimates are applied, often assuming that the Ra value will be 1/4 to 1/9 of the Rz value. WebGrit size and Surface Finish. As an example, on a steel part hardened to 60 HRc, lapped using silicon carbide 500 grit, a pressure of 250 g/cm squared will produce a surface finish of about Ra= 0.2 my (N4) or Rz 0.6-0.8, whereas by reducing the pressure to 50 g/cm squared, a surface finish of about Ra= 0.05 my (N2) or Rz 0.2-0.3 can be obtained.
