OTEC has developed precision finishing technology since 1996, with its machines designed and manufactured in Germany. The systems are built around repeatable, mechanised finishing processes that can achieve consistent surface quality while reducing reliance on manual polishing.

For jewellery workshops and manufacturers, OTEC technology can support processes including grinding, smoothing, deburring, edge rounding and polishing. The aim is greater process control and repeatability while protecting the detail and geometry of the finished piece.

With a range covering mass finishing and electro-finishing systems, different machine configurations can be matched to the required workflow, production volume and desired finish. Hygrade can help determine which solution best suits your workshop and application.
