Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment, leaving a clean surface with a significant specular reflection (still limited by the index of refraction of the material according to the Fresnel equations). [1]
A no. 8 ("mirror") finish requires polishing and buffing compounds, and polishing wheels attached to high speed polishing machines or electric drills. Lubricants like wax and kerosene [ 4 ] may be used as lubricating and cooling media during these operations, although some polishing materials are specifically designed to be used "dry."
Steel plates are very hard for this technique, which is normally used on softer copper plates. So steel engraving also used etching, where acid creates the lines in the plates in the pattern made by selectively removing a thin coating of acid-resistant ground by tools. This is much less effort.
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.
Mirror armour (Russian: зерцало, zertsalo, meaning "mirror"; Chinese: 护心镜, hùxīnjìng, meaning "protect-heart mirror"), sometimes referred to as disc armour or as chahār-āyneh or char-aina (Persian: چهاﺮآﻳنه meaning "four mirrors"; whence Kazakh: шар-айна, şar-ayna), was a type of cuirass used mainly in Asia ...
Both the plate and the carrier are then rotated and the carrier is kept oscillating; this can be better seen in the top view of Figure 2. A downward pressure/down force is applied to the carrier, pushing it against the pad; typically the down force is an average force, but local pressure is needed for the removal mechanisms.
Mirror plates prior to the invention had been made from blown "sheet" glass, and were consequently very limited in size. De Nehou's process of rolling molten glass poured on an iron table rendered the manufacture of very large plates possible. [2] In 1773 English polished plate (by the French process) was produced at Ravenhead.
Along with buffing wheels, particular compounds are used to help polish the material. Two main types of compounds used for silver and gold surfaces are red and blue compounds. Red, also known as jeweler's rouge, polishes without any cutting action. The blue compound is a dryer compound and is used with a grease-less wheel that also does not cut ...
