The CRITT Technical Jet Fluid and Machining is validated since 1985 by the Ministry of Industry and certified "Technological Resource Centre" since 1988. Association law 1901, it is a member of the water jet bureau and club THP, ARFCRT, the Materalia centre and the CARNOT - ICEEL institute. It includes two domains of excellence: machining (from traditional to high-speed) and cutting and cleaning by high-pressure fluid jets.

The services of CRITT Technical Jet Fluid and Machining concerns :
- The integration of new production technologies and investments in order to help companies put the technico-economic offer in accord with its needs. The following domains are concerned: cleaning, surface treatment, decontamination, hydrodemolition, cutting, forming and machining of materials, optimization of the materials transformation settings.
- The development of new products, by accompanying industrialists in their thought so as to better face the very active competition.
- Applied research projects and collective actions so as to draw up the development ideas of S.M.I., search for their future partners, direct projects, put together files destined for financers and participate in the development of applied research actions.
- Technological expertise, by proposing it to SMI, in order to favour the success of a project.
The CRITT TJF&U can also assure the training of personnel regarding cutting by water jet, machining, and digital command, CAD, organization of the work and leading of projects.

A few examples of projects carried out :
- Integration study of a cutting system of steel high mechanical characteristics for bracing ;
