Abstract

Invention concernant des lentilles optiques. Moyen de finition comprenant un outil de façonnage qui comporte une face d'attaque ayant un contour prédéterminé en relation avec le contour requis de la pièce soumise au traitement de finition, et une lame de matériau pourvue de perforations multiples et attachée à l'outil de façonnage de façon à en couvrir la face d'attaque, ce matériau perforé comportant une matière d'imprégnation solide incorporant les particules abrasives. Application notamment à la finition des verres de paires de lunettesInvention relating to optical lenses. Finishing means comprising a forming tool which has a leading face having a predetermined contour in relation to the required contour of the part subjected to the finishing treatment, and a blade of material provided with multiple perforations and attached to the cutting tool. shaping so as to cover the leading face thereof, this perforated material comprising a solid impregnation material incorporating the abrasive particles. Application in particular to the finishing of the lenses of pairs of spectacles
