A patented gap adjusting system makes adjusting the gap a child’s play. The gap can easly and quickly be adjusted from 3 mm to 0.4 mm depending on the customer’s requirements.


ECO Maxi Series

The modular concept of the ECO-Maxi makes it ideal for small series production. Their high-tech design makes these machines extremely economical, with savings being as much as 60 % compared to the cost of conventional finishing. To cater for specific applications, the ECO-Maxi is available in the versions “magnetic”, “wet” and “dry” and as a flexible all-rounder, the “basic” model.
> Clean and bright workpiece surfaces. Completely removes any traces of sanding/grinding and casting skin for perfect results.
> A surface finish equal in quality to that of manual polishing. Puts a shine even on inaccessible areas of intricate workpieces and completely removes oxidation discoloration and any residual investment material.
> Flexible in use. This machine type is the first to use three separate or up to three different finishing processes in a single machine.

> Speed control via frequency inverter
> Bayonet fitting for container
> LCD indicating speed and processing time
> 6 l process container for dry finishing



ECO Mini Series

OTEC’s ECO mini series is unbeatable in terms of cost-effectiveness. This model packs the technology of large industrial disc finishing machines into an amazingly compact format. The patented technology enables the finest granulates to be used, givng a sensational shine comparable to that obtained by manual polishing. In addition, the plastic abrasive medium used prevents any unsightly pitting on the surface of jewelry. A timer makes the machine easy to operate and it works quietly without producing dust.

> Extremely efficient. It is the smallest and most cost-effective “finishing center” on the market.
> For wet finishing. The ECO mini “wet” is used mainly for very small, zero or prototype series, for removing casting skin or traces of sanding or grinding. This makes the subsequent polishing stage much simpler and much faster.
> For dry finishing. The ECO mini “dry” is used mainly for polishing tarnished or worn jewelry.
