Vollkommen glatte Oberfläche ist für diesen in unseren Drehzentren erzeugten Stahl- Gusseisen-Bestandteil der Glasform absolut notwendig. Customers require literally mirror-polished surface, which is technically defined as the surface roughness with Ra values ​​up to 0.2. Only then is it guaranteed that molten glass does not adhere to this part. Chrome-nickel coating performed by rotary welding with hardness up to 60 HRC is not facilitated by the final machining accuracy of 0.02 mm.
