    • PROBLEM TO BE SOLVED: To provide a milling cutter and insert for metal machining.SOLUTION: The milling cutter includes a rotator (1) and a plurality of milling inserts (2) of a cutting edge replaceable type. The plurality of milling inserts are mounted on a plurality of insert seats arranged apart from each other in the peripheral direction at a predetermined pitch. Each milling insert includes an upper surface (13), a lower face (14), and one or more flanks (15, 16) defining two or more replaceable cutting edges (18, 19) uniformly extending between a first endpoint and a second endpoint with the upper surface. The different cutting edges (18, 19) of each milling insert (2) are arranged at different height positions with respect to the lower face (14) of the milling insert and change the pitch between the cutting edges (18, 19) of the milling insert by replacing the tip of at least one milling insert.
    • 要解决的问题:提供用于金属加工的铣刀和刀片。解决方案:铣刀包括转子(1)和多个切削刃可更换型铣刀(2)。 多个铣削刀片安装在以预定间距沿圆周方向彼此分开布置的多个刀片座。 每个铣削刀片包括上表面(13),下表面(14)和限定在第一端点和第二端点之间均匀延伸的两个或更多个可替换切削刃(18,19)的一个或多个侧面(15,16) 与上表面。 每个铣削刀片(2)的不同切削刃(18,19)相对于铣削刀片的下表面(14)布置在不同的高度位置,并且改变铣削刀片的切削刃(18,19)之间的间距 通过更换至少一个铣削刀片的尖端来铣削刀片。
