Investigation of Machining OCr18Ni9 Stainless Steel under Spraying Liquid Nitrogen
Cryogenic machining is considered as an eco-friendly machining process in manufacturing industry. In order to study the influence of cryogenic gas mixture of nitrogen gas and compressed air on machining performance, the experiments of turning 0Cr18Ni9 stainless steel were performed . The experimental results show that cryogenic machining technology can remarkably improve the surface integrity, cutting tool life and chip-breaking performance. Its advantages of improving machinability are especially obvious at higher cutting speeds.
