Surface Finish

Ra is the arithmetic average of surface heights measured across a surface Simply average the height across the microscopic peaks and valleys Ra and RMS are both representations of surface roughness but each is calculated differently Ra is calculated as the Roughness Average of a surfaces measured microscopic peaks and valleys surface roughness tables If you want to print this file then see the PDF format information at the bottom of this page For the best viewing please use your scroll bars to view the full width of the chart


An easy way to convert metric surface call outs to standard U S ones (rms) is to mentally multiply the metric value by 40 For example 1 6 = 63 rms 3 2 = 125 rms and 6 3 = 250 rms And for metric triangle callouts you can approximate one triangle = 250 finish two triangles = 125 finish and Which machine is capable of finishing n8 surface finish? Is it Band saw finish or Milling Finish or Ground Finish? Going for better finish like grinding will increase cost Therefore want to stick with minimum requirement please advise MADHUSUDAN SONTHALIA Manufacturing -

Thickness Parallelism and

In this case techniques will be used during the grinding process to improve a part's flatness and parallelism while obtaining the specified thickness However particular flatness and parallelism values are not guaranteed Honing lapping and superfinishing equipment improve surface finish or geometry to tight tolerances Honing lapping and superfinishing are performed under low speed and pressure conditions resulting in a gentle action as compared to grinding and machining processes
