Abstract

The system has a rotating plate (1) equipped with a treating surface, and an indicating element (14') arranged in thermal contact with the plate. The indicating element indicates exceeding of temperature threshold, where the indicating element is made of a material comprising thermochromic powders whose color changes during exceeding of the temperature threshold. A lapping ring (2) for retaining parts to be treated is arranged on the rotating plate. The indicating element is arranged in contact with a delimitation surface of a central recess (16).
