Velocidades de avance recomendadas para taladrado

Velocidades de avance de perforación estimadas (pulgadas por revolución) según el material, la dureza Brinell y el diámetro del orificio.

Esta tabla muestra solo cifras estimadas. AutoDrill normalmente sugiere utilizar velocidades y avances conservadores siempre que el tiempo de ciclo no sea crítico; controlar la acumulación de calor y realizar un corte adecuado produce un orificio más limpio y una mayor vida útil de la herramienta. Algunos materiales, como el acero inoxidable, se perforan mejor con un corte agresivo, ya que la broca atraviesa material fresco y frío en lugar de una zona calentada por el paso anterior. Siempre consulte al fabricante de la herramienta para conocer las RPM, el empuje y las velocidades de avance sugeridos.
