Abstract

Perfeccionamientos en las máquinas para desbordar y biselar lentes oftálmicas, del tipo en el que una plantilla y una lente que debe ser desbordada según el contorno de la plantilla están soportadas por una espiga giratoria a pequeña velocidad, cuyo eje de rotación es paralelo a una dirección fija, estando dicha espiga montada rotativa en un soporte móvil unido al bastidor de la máquina por una unión que permite unos movimientos del soporte en una primera dirección paralela a la dirección fija y en una segunda dirección perpendicular a la primera dirección, una tecla soportada por el bastidor que coopera con la plantilla para limitar la penetración en el canto de la lente de una muela que gira a gran velocidad y soportada por el bastidor, y en el cual está previsto un dispositivo de guiado apropiado para guiar los movimientos del soporte móvil de acuerdo con una curvatura predeterminada.
