Polishing and fine adjustment :

From a forged or machined blank, using highly specialized specifications and drawings provided by customers, we make pre-forming and finishing operations by polishing.

We use polishing to remove defects and enhance the parts.
This activity is divided into different steps which are all specific operations.
The operations may vary in time from a few minutes to several hours with the same part.
