The finished bearing shaft. Note the superb finish on the shaft.
A 150x view of the shaft surface after machining. This is with a relatively smooth ~16 micron finish.
A 150x view of the shaft surface after polishing. The final finish is between 4 and 8 microns. A 4 micron finish is a mirror finish and is very expensive and difficult to obtain. This is the same view as with the un-polished shaft but only a very uniform reflection can be seen.
