Polishing and buffing are finishing processes for smoothing a workpieces surface using an abrasive and a work wheel or a leather stropTechnically polishing refers to processes that use an abrasive that is glued to the work wheel while buffing uses a loose abrasive applied to the work wheel. For finishing cut a good surface finish is important and the process should complete the size of the machining parts a fine feed should be adopted. It usually involves preparing the edge pieces to form one of the groove weld shapes like V bevel U J Flare V Flare bevel or no preparation at all with square edges to form a square groove.

If the exercise was repeated using machining types other than turning the results may throw up some inconsistencies. Increase the cutting speed feed rate until the quality of the parts finish starts to decrease or the part is starting to move from hold downs. For general CNC turning using an HSS cutting tool a feed rate of 005 020 inches per revolution for roughing and a 002 004 inches per revolution for finishing are recommended.
