conventional abrasive and superabrasives.

Got different finish with different grit of abrasive:
#3 Finish
Also known as grinding, roughing or rough grinding, a preliminary finish applied before manufacturing, Like
deburring and removing excess weld material. It is coarse in appearance and applied by using 36-100 grit abrasive.
#4 Architectural finish
Also known as brushed, directional or satin finish, which is characterized by fine polishing grit lines. It is produced by polishing the metal with a 120-180 grit belt and then softened with an 80-120 grit greaseless compound or a medium no woven abrasive belt.
#4 Dairy or sanitary finish
This finish is commonly used for the medical and food industry and almost exclusively used on stainless steel. This finish is much finer than a #4 architectural finish. It is produced by polishing with a 180-240 grit beltl.
#6 Finish
Also known as a fine satin finish, which is produced by polishing with a 220-280 grit belt.
#7 Finish
A #7 finish is produced by polishing with a 280-320 grit belt and sisal buffing with a cut and color compound. This is a semi-bright finish will still have some polishing lines but they will be very dull.
#8 Finish
Also known as a mirror finish, which is produced by polishing with at least a 320 grit belt, this part will remove all defects on the surface. This finish is sisal buffed and then color buffed to achieve a mirror finish.
How to get a mirror finish:
The first stage:
start with a rough abrasive( perhaps 60 or 80 grit)
The next stage:
uses a finer abrasive such as 120,180,220,240,320,400 and higher grit abrasives, until the desire finish is achieved.
- The rough( i.e. large grit) passes remove imperfection within the metal surface like pits, nicks, lines and scratches.
- The finer abrasive leave progressively finer lines that are not visible to nake eye.
