Aeronautic, space and ammunition

 

The precision machining of complex parts and the machining of materials such as ceramics, titanium, aluminum composite materials allows us to enter in the aeronautics sector. We produce critical parts for military or civilian devices (machined parts for airplanes, helicopters, satellites and drones).

Polis Précis works for civil aviation and military aviation and specializes in prototypes and small series for aeronautics and space.

Wire-in-oil spark erosion is proving to be a most valuable tool for the life time of our tools.
