Grit 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= 02 my N4 or Rz 06-08, whereas by reducing the pressure to 50 g/cm squared, a surface finish of about Ra= 005 my N2 or Rz 02-03 can be obtained...
Although the lapping process is less damaging than grinding, there are two regimes of lapping free abrasive lapping and fixed abrasive lapping Free Abrasive Lapping is when abrasive slurry is applied directly to a lapping plate eg cast iron This is perhaps the most accurate method for producing specimens and causes the least amount of ....
