A segmented broach bar for machining axially separated coaxial bearing bores contained within a component for an internal combustion engine includes axially separated pilot segments and axially separated broaching segments, with at least one of the pilot segments being positioned between a pair of broaching segments. A broach bar has a lead end which first engages the bearing bores, with the broaching and pilot segments having diameters which are sized progressively greater as the distance from the lead end increases, with the broach and pilot segments being sized such that each broach segment produces a bore diameter accommodating the immediately following pilot segment.
La barre de brochage segmentée pour l'usinage des alésages de coussinet séparés dans le sens axial se trouvant dans un composant de moteur à combustion interne comprend des segments pilotes séparés dans le sens axial et des segments de brochage séparés dans le sens axial, au moins un des segments pilotes se trouvant entre deux segments de brochage. Une barre de brochage a une extrémité d'attaque qui s'engage d'abord dans les alésages de coussinet, alors que les segments de brochage et les segments pilotes dont les diamètres augmentent progressivement au fur et à mesure que la distance les séparant de l'extrémité d'attaque s'accroît, les segments de brochage et les segments pilotes étant dimensionnés de telle façon que chaque segment de brochage donne un diamètre d'alésage pouvant recevoir le segment pilote qui suit immédiatement.
