Cryogenic machining as an alternative turning process of normalized and hardened AISI 52100 bearing steel

► Cryogenic machining has been applied on machining of hardened bearing steel AISI 52100. ► Cryogenic machining can considerably prolong tool lifetime and increase productivity. ► Appropriate cutting tool geometry and edge preparation, dedicated to cryogenic application, has to be defined. ► Cryogenic machining has a beneficial impact on surface integrity and so part fatigue life and quality. ► Cryogenic machining represents an alternative process for machining of hardened bearing steels.
