Applications of Surface Finishing processes - IMTMA/T006

Programme Background

To ensure reliable performance and prolonged service life of products, its components require to be manufactured not only with high dimensional and geometrical accuracy but also with high surface finish. The surface finish has a vital role in influencing functional characteristics like wear resistance, fatigue strength, corrosion resistance and power loss due to friction. In case of auto components, surface parameters become more and more stringent to meet the norms in terms of noise levels, pollution, etc. necessitating closer control of surface integrity. Significant progress has been made, in recent years, in wide varieties of surface-finishing technologies including micro finishing, honing, lapping and Burnishing. Since, each process is designed to generate a particular geometrical surface and to correct specific irregularities, selection of a right kind of finishing process is very important to achieve the potential benefits.
