The OTEC ECO-Mini Dry is a compact and economical centrifugal disc finishing machine that provides professional goldsmiths and jewellery designers with a gentle and efficient method for achieving highly smooth and brilliantly polished surfaces.

Dry polishing with granulated walnut shells is a delicate process that will not damage set gemstones or pearls. The fine granulate particles reach even the most inaccessible areas, ensuring exceptionally smooth and refined surfaces. The result is a brilliant shine comparable to hand polishing, achieved in a short processing time – without hardening the surface or rounding off contours.

With its user-friendly timer function, the machine is easy to operate, and the quiet running makes it ideal for workshops where the working environment is a priority.
