Since 1982 industries have used micro-finishing crankshafts. Dynomotive now offer this service.
Super finishing or CASF (Chemically Accelerated Surface Finishing) is a metalworking process that helps reduce stress and friction to metal components.
There is a perception by some that a polished part are better quality and therefore has an inherently higher value, which in fact is true.
However, regardless of how smooth a surface looks there are always peaks and troughs, which results in wear and tear of the part. 
Super finishing reduces the height of the peaks, decreasing both friction and the probability of damage.
With the use of an abrasive paste or liquid in the machine will result in the finely finished end product.
Super finishing is currently used on crankshafts, camshafts, cam followers, valves, valve springs and gears. By no means is this an exhaustive list.
