    • Herein a cutting insert (2) and a gear milling cutter is disclosed. A first major side portion (10a) of an insert body (4) of the cutting insert (2) is provided with a first recess (22a) having a first bottom surface (24a) and a second major side portion is provided with a second recess having a second bottom surface. The first and second bottom surfaces (24a, 24b) extend substantially in parallel with a longitudinal axis (6) of the insert body (4). A first minor side portion (14a) is provided with a third recess (26a) having a third bottom surface (28a) and a second minor side portion (14b) is provided with a fourth recess (26b) having a fourth bottom surface (28b), the third and fourth bottom surfaces (28a, 28b) extending across the longitudinal axis (6). Thus, the cutting insert may be supported in a relevant gear milling cutter against one of the first and second bottom surfaces and against one of the third or fourth bottom surfaces.
    • 公开了一种切削刀片(2)和齿轮铣刀。 切削刀片(2)的刀片主体(4)的第一主要侧部(10a)设置有具有第一底面(24a)的第一凹部(22a)和第二主侧部分 凹部具有第二底面。 第一和第二底表面(24a,24b)基本上平行于插入体(4)的纵向轴线(6)延伸。 第一小侧部分(14a)设置有具有第三底面(28a)的第三凹部(26a)和第二小侧部分(14b),第四凹部(26b)具有第四底面(28b) ),第三和第四底表面(28a,28b)延伸穿过纵向轴线(6)。 因此,切削刀片可被支撑在相关的齿轮铣刀中,抵靠第一和第二底表面中的一个并抵靠第三或第四底表面中的一个。
