Polishing is often used to enhance the appearance of an item, prevent contamination of instruments, remove oxidation, create a reflective surface, or prevent corrosion in pipes. In metallography and metallurgy, polishing is used to create a flat, defect-free surface for examination of a metal's microstructure under a microscope. Silicon-based ...
Electropolishing, also known as electrochemical polishing, anodic polishing, or electrolytic polishing (especially in the metallography field), is an electrochemical process that removes material from a metallic workpiece, reducing the surface roughness by levelling micro-peaks and valleys, improving the surface finish.
Turned, ground, and polished (TGP) is a classification of finishing processes often used for metal shafting. Turning (on a lathe ) creates straight round bars without the strain induced by cold drawing, while grinding and polishing improves the surface finish and roundness for high dimensional accuracy.

Polishing lines will be soft and less reflective than a #4 architectural finish. #7 Finish. A #7 finish is produced by polishing with a 280–320 grit belt or wheel and sisal buffing with a cut and color compound. This is a semi-bright finish that will still have some polishing lines but they will be very dull.
A well-chosen speed for stone polishing causes the rocks within the barrel to slide past each other, with the abrasive grit between them. The result of this depends on the coarseness of the abrasive, and the duration of the tumble. Typically, a full tumble polish from rough rock to polish takes 3–5 weeks, and is done in a minimum of 3 steps.
Over polishing is an issue with silver and can cause harm to the surface of the metal. After polishing, the silver object is rinsed in deionized water and dried with a cotton cloth. [12] Once cleaned and dried the silver is wrapped in acid-free tissue paper and placed in a sealed plastic bag.

Laser polishing, also referred to as laser re-melting, is a type of micro-melting process employed for improving surface quality of materials.As opposed to other conventional polishing processes, this process does not involve removal of materials from the workpiece surface.
