I read an artcle on superpolishing automotive shafts once.... Basically what they do is have the shaft on a lathe and a motorized grinding wheel on the tool post (all computer controlled of course) and the key to it is the pressure and viscosity of the lubricant. It forms a fluid bearing between the shaft and grinding wheel and only allows contact between the tips of the grit particles of the wheel and the remaining peaks on the shaft.
