Abstract
Un trépan à cônes roulants (10) comporte un cône de coupe (14, 15, 16) présentant une paire de rangées adjacentes d'éléments coupants (70, 80) positionnés de manière à diviser la capacité de coupe dans la paroi latérale (5) et dans le fond (7) du trou. La résistance à l'usure, la dureté et la robustesse des éléments coupants (70, 80) dans les rangées adjacentes sont optimisées en fonction du type de coupe réalisée par les rangées respectives. Dans la plupart des applications, les éléments coupants (70) effectuant la coupe dans la paroi latérale vont présenter des surfaces de coupe plus résistantes ou plus dures que les surfaces de coupe des éléments coupants (80) situés dans les rangées et chargés plus spécialement de la coupe dans le fond du trou. De même, les éléments coupants (80) vont généralement être plus robustes que ceux (70) réalisant la taille essentiellement dans la paroi latérale. Les perfectionnements apportés aux matériaux constitutifs permettent de faire varier les qualités du carbure de tungstène mis en oeuvre dans les éléments coupants (70, 80) et concernent l'emploi sélectif de couches d'abrasifs extra-durs tels que le PCD ou le PCBN. Les éléments coupants (70, 80) sont soit des lames rapportées, soit des dents en acier.
