Polishing is the process of creating a smooth and shiny surface by RUBBING it or using a chemical action, leaving a surface with a significant specular reflection (still limited by the index of refraction of the material according to the Fresnel equations.)[1] In some materials (such as metals, glasses, black or transparent stones), polishing is also able to reduce diffuse reflection to minimal values. When an unpolished surface is magnified thousands of times, it usually looks like mountains and valleys. By repeated abrasion, those "mountains" are worn down until they are flat or just small "hills." The process of polishing with abrasives starts with coarse ones and graduates to fine ones. Mechanical properties Edit The strength of polished products can be higher than their rougher counterparts owing to the removal of stress concentrations present in the rough surface. They take the form of corners and other defects which magnify the local stress beyond the inherent strength of the material.[2] Types Edit Metalworking Edit Main article: Polishing (metalworking) Other polishing processes include: Burnishing Mass finishing Tumble finishing Vibratory finishing Sodablasting Woodworking Edit French polishing Wood finishing Other Edit Chemical-mechanical polishing, which is used in semiconductor fabrication Fabrication and testing of optical components Flame polishing, a type of polishing used on glass and thermoplastics Ultra-fine, abrasive paste polishing, polishing for soft or fragile work surfaces Vapor polishing, a method of polishing PLASTICS to optical clarity References Edit Floor Scrubber, ARCHIVED from the original on 2016-08-31, retrieved 2008-01-04.
