Abstract: The present disclosure relates to a polygonal turning insert having primary cutting edges, which individually include a nose edge and two main edges, which converge toward the same. Behind the nose edge, chip-directing guide surfaces are formed, on one hand, with a breast surface included in a knob situated behind the nose edge along a bisector between the main edges, and, on the other hand, with a pair of flank surfaces included in a land there behind. At a distance behind the knob, there is formed a second breast surface, the upper part of which is situated on a higher level than the upper part of the first breast surface. In such a way, it is guaranteed that thin chips, which tend to pass or jump over the first breast surface without being affected by the same, will impinge on the second, higher breast surface and be subjected to guiding by the same.

Abstract translation: 本发明涉及一种多边形车削刀片，其具有主切削刃，该主切削刃分别包括鼻部边缘和两个朝向它们会聚的两个主边缘。 在鼻缘之后，芯片引导引导表面一方面形成一乳头表面，乳房表面包括在位于主棱边之间的平分线之后位于鼻边缘后面的旋钮中，另一方面与一对侧面 表面包括在后面的一块土地上。 在旋钮后面的距离处形成有第二乳房表面，其第二乳房表面的上部位于比第一乳房表面的上部更高的水平上。 以这种方式，可以确保倾向于在第一乳房表面上通过或跳过而不受其影响的薄片将撞击在第二较高乳房表面上并受其引导。
