Abstract
A micro-finishing apparatus for finishing the outer surface of small cylindrical workpieces with repeatability. The apparatus comprises a regulating mechanism rotating and feeding a workpiece against a micro-finishing spool drive mechanism. Planar extents of the regulating mechanism and micro-finishing spool drive mechanism form an opening having a distance that is no greater than the diameter of the workpiece. The workpiece is fed through the opening at an angle by a guide bar. The regulating mechanism rotates the workpiece against the abrasive of the micro-finishing spool drive mechanism and simultaneously feeds it through the apparatus.
