Roscado de acero para herramientas por rango de dureza<\/h1>\n\n\n\n

El roscado es la operaci\u00f3n que se detiene primero cuando una pieza de acero para herramientas se endurece, porque un macho combina un filo de corte con un cuerpo largo y delgado que debe soportar el par de torsi\u00f3n. La pr\u00e1ctica publicada para el roscado de acero se divide en tres rangos de dureza, y cada parte del macho cambia entre ellos, desde el grado de acero r\u00e1pido del macho hasta el porcentaje de rosca completa con el que se prepara el agujero.<\/p>\n\n\n\n

Tres rangos de 5 a 55 HRC<\/h2>\n\n\n\n

Los tres rangos provienen de una serie de ensayos de un fabricante de machos sobre 11 aceros que abarcan de 5 a 55 HRC, realizados para determinar el efecto de la dureza en el roscado. Las recomendaciones que resultaron se reproducen a continuaci\u00f3n. Conviene leerlas como un solo sistema y no como seis filas separadas, porque el dise\u00f1o del macho, el material del macho, la dureza del macho, el tratamiento superficial, el porcentaje de rosca y la velocidad se mueven en conjunto.<\/p>\n\n\n\n

Pr\u00e1ctica recomendada para el roscado de aceros en tres rangos de dureza, reproducida de la Tabla 2 de Tapping, en ASM Handbook, Volumen 16, Machining. (a) Un macho especial debe tener cuatro ranuras, un \u00e1ngulo de ataque positivo de 3 grados, alivio de rosca y un chafl\u00e1n de 3 a 4 hilos. (b) Pueden sustituirse aceros r\u00e1pidos de contenido total de aleaci\u00f3n similar a los aceros indicados. (c) U otro proceso oxidante.<\/em><\/p>\n\n\n\n

Qu\u00e9 cambia cada rango<\/h2>\n\n\n\n

Hasta 30 HRC, un macho est\u00e1ndar de acero r\u00e1pido de uso general es la opci\u00f3n m\u00e1s econ\u00f3mica. Los aceros del grupo T1, M1, M7 y M10 se nombran para ello, con una dureza m\u00ednima del macho de 62 HRC y una superficie de \u00f3xido por vapor, con 75 por ciento de rosca completa preparada en el agujero y una velocidad de hasta 30 m\/min (100 sfm).<\/p>\n\n\n\n

De 30 a 40 HRC, el macho pasa a ser un est\u00e1ndar modificado o un especial, y el material del macho sube a M2 y M3 con una dureza m\u00ednima de 64 HRC. El tratamiento superficial cambia a nitrurado m\u00e1s \u00f3xido por vapor, la preparaci\u00f3n de la rosca baja a 60 por ciento de rosca completa y la velocidad cae a 6 a 14 m\/min (20 a 45 sfm).<\/p>\n\n\n\n

De 40 a 55 HRC, cada elemento est\u00e1 en su condici\u00f3n m\u00e1s severa. El macho tiene que ser un especial, con cuatro ranuras, un \u00e1ngulo de ataque positivo de 3 grados, alivio de rosca y un chafl\u00e1n de 3 a 4 hilos. El material del macho pasa a los grados altamente aleados T15, M3, M33 y M42 con una dureza m\u00ednima de 66 HRC, la superficie es de nuevo nitrurado m\u00e1s \u00f3xido por vapor, y solo se prepara 55 por ciento de rosca completa. La velocidad baja a 0.15 a 3.0 m\/min (0.5 a 10 sfm), por lo que un macho en este rango trabaja lentamente a prop\u00f3sito y un maquinista que lo trate como un macho para acero blando lo romper\u00e1.<\/p>\n\n\n\n

Un punto recorre toda la tabla. A medida que aumenta la dureza de la pieza, se le pide al macho que elimine menos material. El porcentaje de rosca baja de 75 a 55 por ciento, lo que reduce el par de torsi\u00f3n sobre el macho y da a los grados m\u00e1s duros una posibilidad de sobrevivir.<\/p>\n\n\n\n

Velocidades nominales de roscado para acero al carbono y de baja aleaci\u00f3n<\/h2>\n\n\n\n

La tabla siguiente es la lista m\u00e1s amplia de velocidades para machos de acero r\u00e1pido en aceros al carbono y de baja aleaci\u00f3n, y muestra la misma ca\u00edda de velocidad con la dureza en una variedad de grados comunes. Es una referencia \u00fatil para el extremo m\u00e1s blando del trabajo con acero para herramientas, que se rosca m\u00e1s cerca del acero de medio carbono que del rango endurecido anterior.<\/p>\n\n\n\n
