Buffing process :- Buffing is used to give a much higher, lustrous, reflective finish that cannot be obtained by polishing. The buffing process consists in applying very fine abrasives with rotating wheel. Buffing wheels are made of discs of linen, cotton, broad cloth and canvass. They are made more or less firm by the amount of stitching used to fasten the layers of the cloth together. The abrasive is mixed with binder and is applied either on the buffing wheel or on the work. The abrasives may consist of iron oxide chromium oxide, emery etc. The binder is a paste consisting of wax mixed with grease, paraffin and kerosene, or turpentine and other liquid. In this process, work piece is brought in contact with a revolving, cloth buffing wheel that has been charged with very fine abrasive. The abrasives removes minute amount of metal from the work piece, eliminate fine scratch marks and produce a very smooth surface. Buffing is used to apply high luster to the work piece.
