EXTREMELY FAST, EXTREMELY EFFICIENT Centrifugal disc finishing machines from OTEC. The centrifugal disc finishing process is a mass finishing process specially developed for the surface treatment of work pieces. The pieces to be finished are placed in a container in a solution of water and soap (compound) together with abrasives and usually an auxiliary agent. A rotating motion of the process container causes a relative motion between work piece and abrasive which creates a material abrasion and thus a surface finishing on the work piece. This toroidal motion creates a very aggressive...

Dry polishing The dry polishing machines from OTEC achieve finishes as if polished by "hand". The finest polishing granulate ensures minimal material removal in the micro-region and a brilliant shine -without damaging the set stones in the process. The machines ECO-mini dry: low cost with a small footprint and big in results o For very small batches and prototype area o Jewellers, goldsmiths, private households ECO-Maxi dry: highly cost-effective o For small series o Ideal for small jewellery manufacturers, goldsmith workshops ECO-MINI "DRY” AND "WET” With the series ECO-mini, it has been...

THE ECO-MAXI SYSTEM The universal solution - for wet processing, dry and magnetic polishing. With the ECO-Maxi system you have the choice to either have a so called "base unit" which incorporates all three processing procedures, or a machine for just one of the three processes. The ECO-Maxi "magnetic", the ECO-Maxi "wet" and the ECO-Maxi "dry". The modular machine concept of the ECO-Maxi is therefore perfect for smaller batch production. Due to the advanced technology, the machines are characterised by high economic efficiency with which you can save approx. 60% of your production costs....

EASY FINISH SERIES The new development with the best price to performance ratio in this category. The EF series includes several key innovations specially customized for industrial processing of large batches. Thus an improved efficiency is achieved with a noticably better handling capability. The EF series machines are all free standing units for wet processing. Thanks to the technical advancement of the components and a high performance capability, the EF series exhibits a price-performance ratio which was not previously achieved. Thanks to the patented quick adjustment the container gap...

TYPICAL APPLICATIONS The processing media play an essential role in the surface quaility that can be achieved. The following examples show different processing steps and the processing media which are used. Fragmented, very thin-walled precision parts Machine: ECO-Maxi, Easy Finish Patented gap adjustment system prevents the jamming of very thin workpieces Large pieces of jewellery with set-in stones Machine: ECO-mini, ECO-Maxi By using a ring holder, larger rings with stones can also be polished to a high gloss without damages. Walnut shell granulate, e.g. H 1/100, H 1/500 Impregnated...
