Our mission: to help you innovate

Our values: Service and Quality.

Are you a designer, engineer or researcher in a high-tech company or research laboratory? We provide you with effective support for the production of  special machines,  scientific devices and  specific tools . We ensure the production of all mechanical parts or assemblies, from prototypes to industrialization (in small and medium series).

​Our activity : turning, milling, adjusting, grinding and assembly (all machining techniques) of all metals and plastics, as well as the study and creation of plans to realize your projects with a high level of quality. 

At GREM we provide you with our machining expertise to guarantee the success of your project. It is therefore much more than just the production and manufacturing of parts or the subcontracting of machining of mechanical parts. We are rigorous and our goal is to constantly improve our quality: we carry out quality control of the parts with our high-precision metrology equipment that can go down to a hundredth of a millimeter. We manufacture the parts in our workshops in Paris to ensure traceability, quality and responsiveness.
