Turning Toolholders
Portaherramientas estándar ISO para torneado externo, torneado interno, roscado, ranurado y tronzado, compatibles con una amplia gama de sistemas de sujeción y geometrías.
La gama de portaherramientas de torneado de Galtona abarca aplicaciones de torneado externo, torneado interno (barras de mandrinar), roscado, ranurado y tronzado, fabricados según el código del sistema de sujeción ISO (sujeción superior, sujeción superior y de orificio, sujeción de cuña, sujeción de palanca y sujeción de tornillo), con una matriz completa de formas de plaquitas, ángulos de aproximación, ángulos de desprendimiento, orientaciones manuales, tamaños de vástago y longitudes de herramienta.
El torneado externo incluye portaherramientas de acero, cerámica y tipo suizo para los 6 sistemas de sujeción ISO. Las barras de mandrinar para torneado interno (vástago de acero o carburo, con o sin refrigeración interna) cubren el modelo Ø8–60 mm. Los portaherramientas para roscado (SER/SEL externos, SIR/SIL internos) se fabrican con un ángulo de hélice de 1,5°, ajustado al paso y diámetro de la rosca mediante calces angulares.
Los portaherramientas para ranurado están fabricados en acero para herramientas endurecido a 44 HRc, con superficies lisas y dimensiones precisas del alojamiento del inserto, obtenidas tras un tratamiento térmico para mejorar el contacto con el inserto y la resistencia a la tracción. Las cuchillas de tronzado están endurecidas a 55 HRc, con un paralelismo de ±0,03 mm en una longitud de 150 mm y una planitud de 0,05 mm, para cortes precisos y repetibles.
External turning toolholders
External Turning Toolholders
Steel, ceramic, and Swiss-type toolholders across 6 clamping systems and 8 insert shapes.
Galtona's ISO designation covers clamping system (C top, D top+hole, M screw+top or wedge, P lever, S screw), insert shape (C 80°, D 55°, K 55°, R round, S square, T triangle, V 35°, W 80°), approach angle, hand, shank height/width, tool length, and cutting-edge length — e.g. DWLNR 2525M 08.
