Title
(DE) POLIERVORRICHTUNG FÜR OPTISCHE LINSEN
(EN) POLISHING APPARATUS FOR OPTICAL LENSES
(FR) DISPOSITIF DE POLISSAGE DE LENTILLES OPTIQUES
Abstract
(EN) The invention relates to a device for polishing optical lenses, including: a lens holder (4); a means for positioning said lens holder (4); and a means for rotating said lens holder (4) about an axis, wherein said polishing device further includes: a polishing tool (3); a tool holder (3); a means for positioning said tool holder (3); and a means for rotating said tool holder (3) about an axis. Said device moreover includes a ball joint arranged between a shaft (9) secured to the tool holder (3) and the means for positioning said tool holder (3), or between a shaft (9) secured to the lens holder (4) and the means for positioning said lens holder (4), so as to enable a spherical movement of said tool (2) and of said lens. The invention also relates to a method for polishing using the device according to the invention.
(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. Ce dispositif comprend en plus une rotule disposée entre un arbre (9) solidaire du porte-outil (3) et les moyens de positionnement dudit porte-outil (3), ou entre un arbre solidaire du 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.
