The mirror-like finish promotes increased lubrication retention and heat transfer. Standard Finishing Methods: CBF finishing is a cost effective alternative to electro polishing, lapping or drag finishing. REM Surface Engineering Mechanical Or Industrial Engineering Southington, CT 1,806 followers Unlock Improved Performance Results With REM's Isotropic Superfinishing and the ISF® Surface. I do know F1 crankshafts are utilizing this process, but what I would like to know is what media, chemical and process. g. The truth is that while the maximum modulus is 185 GPa, the most useful <110> crystallographic direction has a high 169 GPa, still higher than that of many materials such as. Probably (as long as the cost is acceptable) I will only perform the isotropic superfinishing treatment because nitriding requires special attention and knowledge of the metal alloy of the shaft, the heat treatments it has previously undergone, the desired depth of treatment, etc.
