Title : Burnishing a Super Finishing Process – A Review

Author Name : Aashish Sharma, S.B.S Kalsi

Synopsis :

Burnishing is considered as a super finishing process. In this process, the metallic surface of the work piece undergoes plastic deformation by the pressing action of a hard and highly polished rotating ball or roller. By using finishing processes such as reaming, boring, etc., we can have the good surface finish but there is no affect on the surface characteristics of the material. Improvements in surface finish, surface hardness, wear resistance and corrosion resistance can be achieved by the application of this process. Burnishing parameters such as burnishing speed, burnishing force, burnishing feed, plays an important role in the improvement of the surface characteristics of the material. To select the burnishing parameters to reduce the surface roughness and to increase the surface hardness is especially crucial. The aim of this paper is to critically discuss the affect of different parameters on burnishing.
