Abstract

Une table de perçage (10) comprend un site de rotation de la tige d'entraînement d'un foret monté à proximité du bord de la table et ayant la forme d'une douille d'entraînement (50) montée rotative dans un bâti accessoire (18) posé sur le bâti principal (14, 16). La douille d'entraînement (50) comprend une couronne dentée (54) qui coopère avec la roue dentée démultiplicatrice usuelle (32) de la table de perçage. La roue dentée de démultiplication (32) et la douille d'entraînement (50) ont des ouvertures centrales (40, 52) à sections transversales polygonales identiques.
