  • Theoretical EquationsDifferences in Equation Derivation and ModelingExperimental Relation Between Oken Type and PPS (2*) Equation (2*) represents that the pore radius r of the model is proportional to the 4th root of Q/DP. To put it another way, r is inversely proportional to the 4th root of the number of seconds, that is, the Oken type smoothness. On the other hand, the mean gap G3 of PPS is proportional to an inverse of a cube root of Q/DP. Besides, they are different in the coefficient; 8/p for Oken type and 12 for PPS. This discordance stems from different modeling ideas.Surface Finish Chart (Micron to Grit Conversion Micron to Grit Conversion Table Ra Micron (µm) Grit 0.10 Mirror 0.23 400 0.30 320 0.38 240 0.48 220 0.76

The electropolishing reaction removes material while it improves surface roughness. Because of the material removal, process runtimes are often limited to maintain dimensional tolerances. Limited runtimes result in real world surface roughness improvements from 10 to 35%.

    Surface Finish Degree (Smoothness) Comparison Table between Rz, Ra and RMS for Iron and Steel Castings. What standard can be used for the surface finish degree, or we called smoothness degree for the iron and steel castings? The following comparison table was organized by us. You can find the comparison for the new standard in China for the Ra Surface Roughness Conversion - The Difference Between Ra Sep 05, 2017 · Average Roughness (Ra) and Mean Roughness depth (Rz) are two different but associated methods to measure roughness. Roughness on a machined surface results from the machining process itself. Type of tool, speed of the tool, machine geometer, and the conditions of the machining environment can all cause roughness.
