Title (EN) OPTICAL-GRADE SURFACING TOOL
(FR) OUTIL DE SURFAÇAGE À QUALITÉ OPTIQUE
Abstract:
(EN) The tool includes a base (11) including a rigid carrier (12) and a flexible collar (13) encircling said rigid carrier (12); an elastically compressible interface (16); and a flexible buffer (20) including a central portion (24) that is located in line with the rigid carrier (12) and a peripheral portion (25) that is located transversely therebeyond. This peripheral portion (25) is connected to the carrier (12) exclusively via said interface (16) and via said collar (13), wherein the collar (13) is configured so that the tool (10) is elastically deformable between a rest position that it adopts in the absence of stress and a reference position in which the transverse end second surface (22) of the flexible buffer (20) is pressed against a reference surface (40) that is spherical and of radius comprised between 40 mm and 1500 mm.
(FR) L'outil comporte une embase (11) comportant un support rigide (12) et une collerette flexible (13) entourant ledit support rigide (12); une interface élastiquement compressible (16); et un tampon flexible (20) comportant une partie centrale (24) qui se trouve au droit du support rigide (12) et une partie périphérique (25) qui se trouve transversalement au-delà. Cette partie périphérique (25) est raccordée au support (12) exclusivement par ladite interface (16) et par ladite collerette (13), laquelle collerette (13) est configurée pour que l'outil (10) soit déformable élastiquement entre une position de repos qu'il prend en l'absence de sollicitation et une position de référence où la seconde surface transversale d'extrémité (22) du tampon flexible (20) est plaquée contre une surface de référence (40) qui est sphérique à rayon compris entre 40 mm et 1500 mm.
