Otec’s polishing systems are made entirely in Germany and are unbeatable in terms of precision and cost effectiveness. Goldsmith & Jewellery Supplies are proud to be the South African agents for these quality polishing systems.
The CF machines from OTEC work on the disc finishing principle, an extremely efficient mass finishing process. During this process, the work pieces are immersed in a rotating grinding or polishing granulate in an open, barrel-shaped process container. The medium is rotated by means of a rotating disc which forms the bottom of the container and which is separated from the container wall by an adjustable gap.
