Abstract

EL DISPOSITIVO PARA LA FABRICACION DE LENTES DE CONTACTO TORICAS POR MECANIZADO CON RETIRADA DE MATERIA LLEVA UNA PATILLA (15), SOBRE LA QUE SE FIJA UN DESBASTE DE LENTILLA (6) Y UNA HERRAMIENTA DE CORTE (6) AJUSTABLE RESPECTO AL DESBASTE DE LENTILLA POR UN DISPOSITIVO DE AJUSTE. LA HERRAMIENTA DE CORTE (6) ESTA DISPUESTA SOBRE UNA PALANCA (4) ARTICULADA EN UNO DE SUS EXTREMOS ALREDEDOR DE UN EJE DE ROTACION (7) Y QUE LLEVA, EN EL OTRO EXTREMO, UNA PARTE DEL DISPOSITIVO DE AJUSTE QUE COMPRENDE UN MOTOR ELECTRICO CON UNA BOBINA ELECTRICA (10) QUE ACTUA SOBRE UN IMAN (9) FIJADO A LA PALANCA (4). EL MECANIZADO ESTA CONTROLADO POR UN ORDENADOR. ESTE DISPOSITIVO TIENE UNA GRAN RIGIDEZ Y POSEE UNA GRAN PRECISION, QUE PERMITE LA FABRICACION PARTICULARMENTE DE LENTILLAS TORICAS CON RELIEVES DE ESTABILIZACION.
