Through polishing, all defects are removed from turned 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. The combination of hardening and polishing increases the useful life of parts that undergo this treatment. Machined parts are polished exclusively at FELLER SA or by qualified partners.
