Patent

CA 2245802

The invention concerns a drilling tool for machine tools. The drilling tool comprises a drill body (14) with two chip-conveying grooves which are delimited at their flanks by helically curved ribs (28). Disposed at the end of the drill body (14) is a drill head (22) which comprises two segment parts (62), which are separated from each other by opposite axially aligned chip spaces (60', 60"), and two cutting plates (18, 20) which are each disposed in a recess in the segment parts in the region of an axially parallel radial chip-guide surface (66', 66") at different radial spacings from the drill axis (34) with mutually partially overlapping working regions. At a transition point, the chip-guide surfaces (66', 66") merge into the flanks (84) of the adjacent chip-conveying grooves (26). Disposed at at least one of the transition points is a transition surface (80) which is gradually recessed so that it widens the cross-section of the chip space (66', 66") and merges into a flank of the adjacent chip-conveying groove (26).

L'invention concerne un outil d'alésage pour machines-outils et son procédé de production. L'outil d'alésage comporte un corps de foret (14) muni de deux rainures d'acheminement des copeaux délimitées sur leurs flancs par des nervures (28) hélicoïdales. Une tête d'alésage (22) montée sur la face du corps de foret (14) présente deux parties de segments (62) séparées l'une de l'autre par des logements de copeaux (60', 60") opposés, orientés dans le sens axial, ainsi que deux matrices de découpage (18, 20) situées à différentes distances radiales de l'axe du foret (34), qui comportent des zones de travail se chevauchant mutuellement en partie et sont disposées chacune dans une cavité des parties de segment, dans la zone d'une surface de guidage des copeaux (66', 66") radiale parallèle à l'axe. Les surfaces de guidage des copeaux (66', 66") se confondent en un point de transition avec les flancs (84) des rainures d'acheminement des copeaux (26) adjacentes. Il est prévu au moins une surface de transition (80) en retrait progressif qui élargit la section du logement de copeaux (66', 66"), se transforme en un flanc de la rainure d'acheminement des copeaux (26) adjacente et est disposée en au moins un des points de transition.
