Buffing wheels are designed to perform two important functions in the metal polishing process:-
(1) to carry the abrasive buffing compound across the work surface to produce a cutting and colouring action
(2) where required, to generate sufficient heat to permit burnishing the work surface
Sisal buffs are available in a wide variety of constructions. There are many applications where they can be used to produce a more aggressive buffing action and therefore require further research depending on your particular buffing operation.
