French precision machining specialist Mecachrome (Hall B, stand C155) will be highlighting its new cryogenic machining technology at this year’s Show. Following several years of research and development, the company will soon start using the technique for series production of a titanium part for the CFM LEAP engine at its Evora plant in Portugal.
Following the inauguration of this initial cryogenic machining centre in November, the technology will be deployed at other Mecachrome sites for a total investment of €30m. The group, which has annual sales of €400m, operates a total of 14 facilities worldwide.
The company says the move reflects the increasing use of titanium for aerospace applications. Mecachrome estimates growth of titanium in aerospace at 9% per year, compared with 3% for aluminium and 15% for composites.
Jean Dominique Thevenin, Mecachrome industrial director, explains that the advantages of the liquid nitrogen-based technology include enhanced cooling compared with conventional oils, faster machining rates, reduced tool wear and increased competitiveness. The company expects to achieve a 35% improvement in productivity thanks to the new technique.
