A UNIQUE KNOW-HOW

 Numerically controlled polishing machine

Polishing Stations for High Performance Optics

Safran Reosc supplies optical surface processing solutions, covering the complete cycle lapping, grinding, polishing, figuring and smoothing. Many equipment are part of Safran optical workshop and have already been delivered for our world wide customers.

All our solutions use standard industrial robots, CNC machines, fitting heads and various tools adapted to cover the main processing steps. Our computer assisted manufacturing software called NanoCam offers user friendly control of the processes and contains the intelligence to predict result of the processing cycle in preparation. Thanks to the easiness of use and our complete operator training, our customers can easily fine tune their processing strategy and be directly operational, to reach the nanometer accuracy.
