Special mechanical parts of medium and large dimensions


SEVA is the ideal partner for the custom machining of tools and/or special mechanical parts. Equipped with a diverse range of machinery, we machine complex shapes on hard materials of medium and large dimensions.



Turnkey projects, from the study of the foundry to the assembly through machining, all in an integrated digital chain.

Custom machining

Our design office and our methods department study the project and proceed to the programming and simulations necessary to optimize the manufacturing process and guarantee the precision of each part produced.

This design phase, which is crucial for the quality of the parts, is based on simulation of the machining paths (NC Simul) and the know-how of our experts.

Once the studies have been validated, the part is machined on Computer Numerically Controlled (CNC) machines and, according to the needs, integrates the various required finishes: manual or automated polishing, fitting, welding, ...

Supported materials

Thanks to their high torque and rigidity, our machines are suitable for machining high-hardness materials (alloyed steels, stainless steels, nickel-based or cobalt-based superalloys, titanium...) whether they are produced within our specialized foundry or sourced from other suppliers (rough castings, forgings, rolled materials...). We also machine all other types of metal grades (aluminum, copper-based alloys, cast iron...).
