Title
(FR) DISPOSITIF DE POLISSAGE DE LENTILLES OPTIQUES
Abstract
(FR) L'invention a trait à un dispositif de polissage de lentilles optiques, comprenant un porte-lentille (4), des moyens de positionnement dudit porte-lentille (4) et un moyen de rotation dudit porte-lentille (4) autour d'un axe, comprenant en outre un outil (2) de polissage, un porte-outil (3), des moyens de positionnement dudit porte-outil (3) et un moyen de rotation dudit porte-outil (3) autour d'un axe, caractérisé en ce qu'il comprend en plus une rotule disposée entre le porte-outil (3) et les moyens de positionnement dudit porte-outil (3), ou entre le porte-lentille (4) et les moyens de positionnement dudit porte-lentille (4), de sorte à permettre un déplacement sphérique dudit outil (2), respectivement de ladite lentille. L'invention concerne également un procédé de polissage par le moyen d'un dispositif selon l'invention.
