Title (EN) TURNING INSERT
(FR) PLAQUETTE DE TOURNAGE
Abstract:
(EN) A turning insert (1) comprising a top surface (8), an opposite bottom surface (9), a reference plane (RP) located parallel to and between the top surface (8) and the bottom surface (9), a center axis (A1) extending perpendicular to the reference plane (RP) and intersecting the reference plane (RP), the top surface (8) and the bottom surface (9). Side surfaces (13, 13', 13") connects the top surface (8) and the bottom surface (9). Three nose portions (15, 15', 15") are formed symmetrically relative to the center axis (A1). Each nose portion (15, 15', 15") comprising a first cutting edge (11), a second cutting edge (12) and a convex nose cutting edge (10) connecting the first (11) and second (12) cutting edges. In a top view the first (11) and second (12) cutting edges on the same nose portion (15) forms a nose angle (a) of 25-50° relative to each other. The distance from the first cutting edge (11) to the reference plane (RP) varies in such a way that that this distance is decreasing at increasing distance from the nose cutting edge (10).
(FR) L'invention concerne une plaquette de tournage (1), laquelle plaquette comprend une surface supérieure (8), une surface inférieure opposée (9), un plan de référence (RP) disposé parallèlement à la surface supérieure (8) et à la surface inférieure (9) et entre ces dernières, un axe central (A1) s'étendant perpendiculairement au plan de référence (RP) et croisant le plan de référence (RP), la surface supérieure (8) et la surface inférieure (9). Des surfaces latérales (13, 13', 13") relient la surface supérieure (8) et la surface inférieure (9). Trois parties de nez (15, 15', 15") sont formées de façon symétrique par rapport à l'axe central (A1). Chaque partie de nez (15, 15', 15") comprend un premier bord de coupe (11 ), un second bord de coupe (12) et un bord de coupe de nez convexe (10) reliant les premier (11) et second (12) bords de coupe. En vue de dessus, les premier (11) et second (12) bords de coupe sur la même partie de nez (15) forment un angle de nez (a) de 25 à 50° l'un par rapport à l'autre. La distance à partir du premier bord de coupe (11) jusqu'au plan de référence (RP) varie de telle sorte que que cette distance diminue à une distance croissante à partir du bord de coupe de nez (10).
