Descripci\u00f3n<\/strong>
\nLas coronas est\u00e1n fabricadas en HSS bimet\u00e1lico d\u00factil, resistente a la rotura y estable. Los diente de sierra est\u00e1n hechos de material M42 (Co8) de alta calidad. Se utilizan para la formaci\u00f3n de aberturas. La ejecuci\u00f3n de rosca 5\/8-18 UNF incluye las roscas de LS 32 a LS 210. El mango para coronas adecuado es LSS 2.<\/p>\n

Ventajas<\/strong>
\nSerrado econ\u00f3mico de orificios redondos.
\nSin traqueteo gracias a la divisi\u00f3n de dientes variable.
\nAlta precisi\u00f3n de concentricidad.
\nBuen desalojo de viruta.
\nCentrado y guiado c\u00f3modos de la corona gracias a la broca de centrado HSS intercambiable.
\nPara la mejor expulsi\u00f3n del material serrado, el mango de corona se suministra con un muelle de expulsi\u00f3n.<\/p>\n

Datos t\u00e9cnicos<\/strong>
\nProfundidad de corte, m\u00e1x.: 31 mm
\n\u00f8 exterior, unid.\u00a0m\u00e9trica: 57 mm
\nr.p.m. desde, aceros hasta 1.200 N\/mm\u00b2: 150
\nr.p.m. desde, aceros resistentes al \u00f3xido y al \u00e1cido: 75
\nr.p.m. desde, metales blandos no f\u00e9rricos: 200
\nr.p.m. desde, termopl\u00e1sticos, pl\u00e1sticos reforzados con fibra (PRFV\/PRFC): 250<\/p>\n

Recomendaciones de uso<\/strong>
\nTener en cuenta las revoluciones recomendadas.
\nLa broca de centrado debe estar integrada en el mango y sobresalir al menos 3 mm (1\/8″) sobre los dientes de la corona.
\nAl serrar metales es aconsejable usar aceite de corte de buena calidad. Con aceite de corte se consigue una marcha m\u00e1s suave y una vida \u00fatil m\u00e1s larga de la corona. Excepci\u00f3n: No usar aceite de corte en el trabajo de materiales de aluminio, utilizar petr\u00f3leo en lugar de aceite.
\nLas coronas HSS son adecuadas para el mecanizado de acero inoxidable (INOX). Para evitar la corrosi\u00f3n, se deben eliminar de la pieza de trabajo las part\u00edculas resultantes del proceso. Es recomendable una limpieza de la pieza de trabajo con medios qu\u00edmicos y mec\u00e1nicos (decapar, pulir, etc.).
\nTodos los dientes deben atacar uniformemente. Evitar movimientos pendulares al serrar para impedir roturas de dientes.
\nEvitar el sobrecalentamiento.
\nTener en cuenta la profundidad de corte m\u00e1xima.<\/p>\n

Recomendaciones de seguridad<\/strong>
\nEn caso de utilizarse prolongadores de mango, no se puede sobrepasar el n\u00fam. de revoluciones recomendadas de las coronas. \u00a1Peligro de accidente!<\/p>\n
