What is the Buffing Process?
Buffing is a surface finishing process, which is performed after polishing for providing a high luster to be polished surface.
Buffing is a surface finishing process used to shine wood, metal, or composites using a wheel generally made up of cotton.
The below figure shows the basic diagram of the buffing process.
As buffing is the surface finishing process, it removes a very less amount of material.
Buffing does not maintain flatness or roundness. It is used only to obtain very smooth reflective surfaces just like automotive parts.

Construction of Buffing wheel
Generally, the wheels used in the buffing process are made up of cloth (for example, wool, flannel, cotton, or muslin) or the fiber which is charged with loose abrasive grains. The buffing belts are made in the same way as wheels.
A very fine abrasive is used for being charged to these wheels or belts and charging is generally done by using sticks made up of abrasive or/and wax.
Applications of Buffing Process
The buffing process is used for the following purposes:
- To remove scratches, coatings, oxides from the surface of the workpiece.
To finish the following components:
- Tools, fixtures, and sports items
- Household utensils and appliances
- Automobile, bicycle, motorcycle parts.
