The Polishing Process
Polishing is one of the oldest processing methods, first used on the making of stoneimplements.
Polishing is one finishing loose abrasive process, used to generate surfaceswith very high tolerances in geometry, surface integrity, and roughness characteristics.
It is still one of the most important finishing methods.
Polishing particles remove smallelements of a surface and make them smooth.
This smoothness is obtained by rubbing thesurface with the polishing particles with a rotating disk.
Polishing is the best methodtoday to obtain the finest surface.
High accuracy and ultra-precision technology areindispensable ingredients for polishing today.
Polishing uses a larger number of multi point or random cutting edges for effectivematerial removal.
Abrasive finishing processes are accepted in a wide range of materialapplications and industries.
Typical examples are finishing of various components used inaerospace, automotive, mechanical seals, fluid handling, and many others precisionengineering industries.
Polishing is a final process that usually follows lapping to give the final surface characteristics of size,surface roughness,and flatness required for the parts.
Polishing is used in many materials from steels to composite ceramics.
It does not create a good planarization of the parts which should be done in lapping prior to polishing,since it corrects flatness in low discrepancies not in a big scale.
Polishing is primarily considered to have mostly three-body abrasive mechanisms.
This is due to the fact that it uses grains that remain loose and can roll and slide in the pad.
Although some abrasive grains embed into the polishing pad leading to two-body abrasion.
