Cutting turning tools
Sometimes the best quality of the surface of the parts is achieved not when polishing, but immediately when turning with industrial diamond, as, for example, when turning parts from gold.
It turns out an ideally shiny surface.
And since after diamond turning no further processing is required, the edges and chamfers, the shape of which is breached during polishing, remain intact.
True, the diamond is very fragile, and with it must be handled with care.
