HB-Superfinishing:

The surface roughness after HB-superfinishing will be less than Ra0.1μm from Ra6.3μm.

The skin hardness increases depending on the initial hardness by 5,10,50,150 %.

The fatigue strength increases by 10,20,50,200 %.

The surface bearing extends up to 80–90 %.

In principle, HB-superfinishing technology excludes the necessity of using of abrasive in any of its combinations –

discs, bands, pastes etc.

The residual stresses are converted into the compressive stresses............................
