Abstract

Cette invention se rapporte à un procédé de polissage de pierre précieuse et à une machine permettant la mise en pratique de ce procédé de polissage de pierre précieuse. La machine comprend un dispositif de support monté mobile par rapport à un moyen de polissage, un moyen de fixation pour fixer la pierre précieuse qu'on désire polir, le moyen de fixation étant monté mobile par rapport au dispositif de support de manière à permettre soit la mise en contact soit la séparation de la pierre précieuse et du moyen de polissage, et un moyen de surveillance comprenant un transducteur de réactance capable de surveiller le déplacement du moyen de fixation par rapport au dispositif de support.
