Title
(EN) CUTTING INSERT FOR CHIP-BREAKING MACHINING OF METALS
(FR) PIECE RAPPORTEE DE COUPE DESTINEE A L'USINAGE DE METAUX PAR TAILLE DE COPEAUX
Abstract
(EN)
An indexable cutting insert for chip-breaking metal machining comprises an upper surface or chip surface, a lower bottom surface which is substantially plane parallel to the upper surface, and at least a side surface extending between said surfaces, which forms an acute angle with the upper surface and an obtuse angle with the bottom surface. The side surface(s) (5) has/have at least two bulging portions (13, 13', 13'') which are intended to function as support points or surfaces against the support surface(s) (3', 4', 3'', 4'') in an insert seat. Thereby, it is not necessary to provide any support points in the insert seat, which considerably simplifies the manufacturing of the same.
(FR)
Une pièce rapportée de coupe indexable, destinée à l'usinage de métaux par taille de copeaux, comporte une surface supérieure ou surface de taille, une surface inférieure sensiblement parallèle à la surface supérieure et au moins une surface latérale, disposée entre les surfaces précédentes, qui forme un angle aigu avec la surface supérieure et un angle obtus avec la surface inférieure. La(les) surface(s) latérale(s) (5) a(ont) au moins deux parties en saillie renflées (13, 13', 13'') qui sont conçues pour servir de points ou de surfaces d'appui contre la(les) surface(s) d'appui (3', 4', 3'', 4'') d'un siège de pièce rapportée. De cette manière, il n'est pas nécessaire de disposer de points d'appui au niveau du siège de la pièce rapportée, ce qui permet de simplifier considérablement la fabrication de cette pièce rapportée.
