Detail, all defects are removed from turned, and usually also hardenedhardening (harden / hardened)Increasing the hardness of steel by cooling from a temperature within or above the transformation range.
Detail parts. To accomplish this, they are mixed with ceramic media, abrasives and additives. This mixture is agitated in vibrating basins for several hours, or even several days.
Once they have been polished, the parts have a much better surface finish, are smoother, and shinier (≤ Ra 0,1 μm).
The combination of hardening and polishing increases the useful life of parts that undergo this treatment.
Machined parts are polished exclusively at Polydec SA workshops.
