Introduction<\/h2>\n\n\n\n

D\u00e9fis li\u00e9s au traitement des lentilles optiques \u00e0 rev\u00eatement 3D Avec l'\u00e9volution des dispositifs AR\/VR, des HUD automobiles et des syst\u00e8mes d'imagerie haut de gamme, la demande de lentilles optiques \u00e0 rev\u00eatement 3D a explos\u00e9. Ces rev\u00eatements - souvent des films di\u00e9lectriques ou fonctionnels multicouches (tels que ITO, SiO\u2082 ou MgF\u2082) - sont extr\u00eamement sensibles aux contraintes m\u00e9caniques et aux effets thermiques.<\/p>\n\n\n\n

Les m\u00e9thodes de d\u00e9coupe traditionnelles, notamment le meulage, le fil diamant\u00e9 alternatif ou la d\u00e9coupe au laser, provoquent souvent une d\u00e9lamination du rev\u00eatement, des microfissures ou des dommages thermiques, ce qui r\u00e9duit le rendement et augmente les co\u00fbts de polissage.<\/p>\n\n\n\n

Pour relever ces d\u00e9fis, Vimfun a mis au point le logiciel Syst\u00e8me de coupe \u00e0 fil diamant\u00e9 sans fin<\/a>Ce syst\u00e8me est con\u00e7u pour les applications optiques de pr\u00e9cision. Sa structure sans fin en boucle ferm\u00e9e assure une vitesse constante, une tension stable et un refroidissement uniforme, \u00e9liminant ainsi les dommages caus\u00e9s au rev\u00eatement \u00e0 la source.<\/p>\n\n\n\n

Configuration et param\u00e8tres du test<\/h2>\n\n\n\n

Un essai comparatif contr\u00f4l\u00e9 a \u00e9t\u00e9 r\u00e9alis\u00e9 pour \u00e9valuer le fil diamant\u00e9 sans fin de Vimfun dans la d\u00e9coupe de lentilles optiques rev\u00eatues en 3D.<\/p>\n\n\n\n

Mat\u00e9riau : Lentille en verre optique \u00e0 rev\u00eatement 3D (\u230030 mm, \u00e9paisseur du rev\u00eatement \u22481,5 \u03bcm, film di\u00e9lectrique multicouche).<\/p>\n\n\n\n

\u00c9quipement : Machine \u00e0 couper le fil diamant\u00e9 sans fin Vimfun (Mod\u00e8le SGI20<\/a>).<\/p>\n\n\n\n

Param\u00e8tres de coupe : vitesse du fil 50m\/s, vitesse d'avance 0,3 mm\/min, tension 150 N, arrosage \u00e0 l'eau d\u00e9ionis\u00e9e.<\/p>\n\n\n\n

Demande de d\u00e9coupe : prot\u00e9ger la couche 3D contre les dommages caus\u00e9s par la chaleur ou la force de d\u00e9coupe.<\/p>\n\n\n\n

R\u00e9sultats des tests et observations<\/h2>\n\n\n\n

Au cours de plusieurs essais, le fil diamant\u00e9 sans fin de Vimfun a d\u00e9montr\u00e9 une coupe en douceur et sans vibration. Les rev\u00eatements 3D sont rest\u00e9s totalement intacts - aucun d\u00e9collement, fissure ou rayure de surface n'a \u00e9t\u00e9 observ\u00e9.<\/p>\n\n\n\n

image microscopique des bords coup\u00e9s de Vimfun<\/p>\n\n\n\n

L'analyse microscopique montre que les \u00e9chantillons coup\u00e9s en va-et-vient pr\u00e9sentaient un l\u00e9ger \u00e9caillage du rev\u00eatement sur les bords, tandis que le fil sans fin Vimfun produisait des bords de rev\u00eatement propres et continus. Les d\u00e9bris de coupe \u00e9taient plus fins, l'enl\u00e8vement des copeaux \u00e9tait plus r\u00e9gulier et la brillance de la surface s'est consid\u00e9rablement am\u00e9lior\u00e9e.<\/p>\n\n\n\n

Explication technique<\/h2>\n\n\n\n

Mouvement sans fin \u00e0 vitesse constante :<\/p>\n\n\n\n

Le fil sans fin \u00e9limine les cycles d'inversion. La fluctuation de la vitesse reste inf\u00e9rieure \u00e0 \u00b10,3%, ce qui \u00e9vite les contraintes d'acc\u00e9l\u00e9ration transitoires qui provoquent des microfissures dans les rev\u00eatements.<\/p>\n\n\n\n

Stable Contr\u00f4le de la tension : <\/p>\n\n\n\n

La servocommande de pr\u00e9cision assure une distribution uniforme des contraintes le long du fil, minimisant ainsi les concentrations de contraintes locales - id\u00e9al pour les substrats recouverts d'une fine couche.<\/p>\n\n\n\n

Processus de coupe \u00e0 froid :<\/p>\n\n\n\n

Le refroidissement par liquide \u00e9limine efficacement la chaleur ; la zone affect\u00e9e thermiquement est pratiquement nulle. L'augmentation de la temp\u00e9rature du rev\u00eatement reste inf\u00e9rieure \u00e0 3\u00b0C, ce qui maintient la stabilit\u00e9 du film.<\/p>\n\n\n\n

Syst\u00e8me de roues de guidage de haute pr\u00e9cision :<\/p>\n\n\n\n

Le faux-rond de la roue \u22641 \u03bcm assure un mouvement fluide et une rayure minimale de la surface, r\u00e9duisant le volume post-polissage de plus de 30%.<\/p>\n\n\n\n

Conclusion : Une nouvelle norme pour une d\u00e9coupe optique sans dommages<\/h2>\n\n\n\n

Les r\u00e9sultats des tests confirment que le fil diamant\u00e9 sans fin de Vimfun permet d'obtenir une v\u00e9ritable \"absence de dommages au rev\u00eatement\" lors de la d\u00e9coupe de lentilles optiques \u00e0 rev\u00eatement 3D.<\/p>\n\n\n\n

Sa vitesse constante, sa tension constante et sa technologie de coupe \u00e0 froid am\u00e9liorent consid\u00e9rablement la qualit\u00e9 de la surface et la fiabilit\u00e9 du processus, ce qui en fait l'outil id\u00e9al :<\/p>\n\n\n\n
