Title (EN) A CUTTING INSERT FOR TURNING WITH CHIP-BREAKER ARRANGEMENT PROVIDING ROOM FOR A COOLING JET
(FR) INSERT DE DECOUPE ROTATIF AVEC DISPOSITIF BROYEUR DE COPEAUX, PERMETTANT LE PASSAGE D’UN JET REFROIDISSEUR
Abstract:
(EN) The present invention relates to a cutting insert for turning. The cutting insert (10) comprises a polygonal body of a hard, wear-resistant material, which has an upper surface (12) and a lower surface, and a plurality of edge surfaces (13,14) uniting said surfaces. At least one chip-breaker arrangement (22) is provided in at least one of the lower and upper surfaces. At least one rounded cutting corner (11 ), provided with a nose-cutting edge (19), is formed at a nose portion (21 ) at the area of the intersection area of two edge surfaces. Said cutting corner defines a bisector (B). The chip-breaker arrangement (22) comprises two elongate chip-breaker segments (22A.22B) having an opening (24) provided therebetween intended to give room for a cooling jet directed toward said opening (24).
(FR) Cette invention concerne un insert de découpe rotatif. L’insert de découpe (10) se compose d’un corps polygonal, fait d’un matériau dur et résistant à l’usure, doté d’une surface supérieure (12) et d’une surface inférieure, ainsi que d'une pluralité de surfaces de bord (13,14) qui relient lesdites surfaces. Au moins un dispositif broyeur de copeaux (22) est utilisé dans au moins l'une des surfaces inférieure ou supérieure. Au moins un bec de découpe arrondi (11), doté d'un bord de découpe de nez (19), est formé au niveau d'une section de nez (21) au niveau de l’intersection de deux surfaces de bord. Ce bec de découpe définit une bissectrice (B). Le dispositif broyeur de copeaux (22) se compose de deux segments broyeurs de copeaux allongés (22A, 22B) séparés par une ouverture (24) permettant le passage d’un jet de refroidissement dirigé vers ladite ouverture (24).
