    • 12. A rotationally drivable milling cutter has a cylindrical carrier body (10), which is equipped on its circumference with a plurality of cutting bodies (12) comprising a cutting material that is harder than hard metal. The cutting bodies (12) are embodied in platelike form and are each embodied and disposed such that the leading region of the radially outer circumferential edge forms the cutting edge, the adjacent side face (15) forms the first face with a negative rake angle, and the top face (17) diametrically opposite the bottom face forms the flank. To that end, the cutting bodies (12) are each secured with their bottom face on the end face of blind bores (30), in the circumferential face thereof, that are oriented with the angle to the shortest connecting line between the center point of the end face and the center longitudinal axis of the carrier body (10) such that the side face (15) adjacent to the cutting edge forms the predetermined rake angle.
    • 可旋转驱动的铣刀具有圆柱形的承载体(10),其圆周上装有多个切削体(12),切削体(12)包括比硬质金属更硬的切削材料。 切割体(12)以板状形式实施,并且各自被实施和布置成使得径向外周边缘的前导区域形成切割边缘,相邻的侧面(15)以负的前角形成第一面, 并且与底面直径相对的顶面(17)形成侧面。 为此,切割体(12)各自的底面被固定在盲孔(30)的端面上,在其圆周面上以与最短连接线的角度定向在中心点 承载体(10)的端面和中心纵向轴线,使得与切削刃相邻的侧面(15)形成预定的前角。

    • A cutting insert (10) having two end portions (12', 12") and an intermediate portion (14) extending longitudinally between the two end portions (12', 12"). The intermediate portion has N side surfaces (20) and N primary cutting edges (22). The N primary cutting edges (22) are formed at the intersection of adjacent side surfaces (20). Each one of the N primary cutting edges (22) extends from one end portion to the other end portion. At least N secondary cutting edges (28', 28") formed on at least one of the two end portions (12', 12"). A cutting corner (30', 30") is formed between a primary cutting edge (22) and a secondary cutting edge (28', 28"). Each secondary cutting edge extending away from the cutting corner in a direction generally away from the intermediate portion (14).
    • 具有两个端部(12',12“)和在两个端部(12',12”)之间纵向延伸的中间部分(14)的切削刀片(10)。 中间部具有N个侧面(20)和N个主切削刃(22)。 N个主切削刃(22)形成在相邻侧面(20)的相交处。 N个主切削刃(22)中的每一个从一个端部延伸到另一个端部。 形成在两个端部(12',12“)中的至少一个上的至少N个次级切削刃(28',28”)。 在主切削刃(22)和次切削刃(28',28“)之间形成切削角(30',30”)。 每个副切削刃沿着大致远离中间部分(14)的方向远离切割角延伸。
