(FR) DISPOSITIF DE DÉTACHEMENT D'AU MOINS UNE BAVURE D'UNE EMBOUCHURE D'AU MOINS UN TROU PERCÉ TRANSVERSAL D'UNE PIÈCE, STATION DE PERÇAGE POURVUE DU DISPOSITIF ET PROCÉDÉ DE DÉTACHEMENT DE LA OU DES BAVURES AU MOYEN DE LA STATION DE PERÇAGE
Abstract
(DE)
Vorrichtung (1) zum Lösen mindestens eines Grats (2) von einer Mündung (3) mindestens eines Quer-Bohrlochs (4) eines Werkstücks (5), wobei die Vorrichtung (1) einen langgestreckten Schaft (7) aufweist, wobei der Schaft (7) in ein Längs-Bohrloch (11) des Werkstücks (5) einführbar und darin positionierbar ist. Zur Vermeidung einer Kollision des Schafts (7) mit mindestens einem Bohrer (12) zum Bohren des mindestens einen Quer-Bohrlochs (4) weist die Vorrichtung (1) mindestens eine Hohlkehle (13) auf.

(EN)
A device (1) for detaching at least one burr (2) from an opening (3) of at least one transverse borehole (4) of a workpiece (5), wherein the device (1) has an elongate shank (7), wherein the shank (7) can be introduced into a longitudinal borehole (11) of the workpiece (5) and can be positioned therein. To avoid the shank (7) colliding with at least one drill (12) for drilling the at least one transverse borehole (4), the device (1) has at least one fillet (13).

(FR)
L'invention concerne un dispositif (1) pour détacher au moins une bavure (2) d’une embouchure (3) d’au moins un trou percé transversal (4) d’une pièce (5), le dispositif (1) présentant une tige (7) allongée, la tige (7) pouvant être introduite dans un trou percé longitudinal (11) de la pièce (5) et pouvant y être positionnée. Afin d’éviter une collision entre la tige (7) et au moins un foret (12) destiné à percer au moins un trou percé transversal (4), le dispositif (1) présente au moins une gorge (13).
