Wheel speed for final polishing has to be set at a second position (about rpm)A small stream of water is directed at the center of the rotating wheelFinal Polishing Final polishing is very similar to that used for rough polishingAluminum oxide is the most popular final polishing abrasive for ferrous and non ferrous materials.

Electroless chemical polishing of stainless steel parts this entry appended to this thread by editor in lieu of spawning a duplicative threadQHiI'm looking for a simple process to polish tiny parts that cannot be polished mechanically.
QCan anyone suggest a chemical polishing solution composition and electrolytic polishing solution composition for high speed steel Can I use phosphoric acid, sulphuric acid and chromic acid to electropolish high speed steel since this solution is suitable for low carbon steels according to books
Chemical polishing of refractory metals is often performed after mechanical polishing to improve polarised light response (e.g for Zr, Hf), or to remove minor deformation (e.g Nb, Ta, V)In general, a ground specimen is immersed in the polishing agent, or swabbed with the solution, until a polish is obtained, and it is then etched or
Metallographic Soft or Welding Steel EtchantsThe most common etchant for low carbon steels or weld steels is Nital, however, there are a lot of other potential etchant for speicalized etchingA good resouce for additional etchants can be found with the etchant database provided by PACE Technologies.
Chemical Deburring Polishing Deburr is a revolutionary process for deburring most types of carbon steelThis unique electroless chemical process removes burrs on steel parts which are created by cutting, milling, forging, and molding, without distorting even the most intricately shaped parts.
