Created in 2005, the Study and Research Centre for Cutting Tools brings together researchers from the Mechanics and Rheology Laboratory of François-Rabelais University and Sandvik Coromant's R&D engineers to work on collaborative research projects.

Like the other CERs, the CEROC is an R&D tool open to regional companies, and an innovative training centre, at the interface between university and business.

Combining the mastery of production conditions in industrial companies with the laboratory's expertise in characterising and modelling the behaviour of materials and surfaces, the CEROC is an ideal place to optimise its machining concepts and achieve productivity gains.
