多效材料移除刀具
摘要：
材料移除刀具(100)，比如用于形成阀座表面的材料移除刀具(100)，其包括整体式的或可分离的直径减小的周向刀片壳体(106)，该直径减小的周向刀片壳体(106)包括与其结合的多个刀片(120)。所述多个刀片(120)包括相对于所述材料移除刀具(100)的轴线(112)在不同轴向和径向位置处的切削表面(122)。在不同轴向和径向位置处的切削表面(122)以与轴线(112)成不同的角度布置，且至少一个刀片上的至少一个切削表面(122)相对于所述轴线(112)成约45度的角度。切削表面(122)可设置在一种刀片类型上或不同的刀片类型上且可具有不同的切削表面(122)组合。当周向地布置在所述刀片壳体(106)上时，形成了N效材料移除刀具(100)。还公开了利用所述N效材料移除刀具(100)加工的方法。
摘要（英）：

Material removal tool (100), such as for forming surfaces of valve seats, includes an integral or separable reduced diameter circumferential insert housing (106) including a plurality of inserts (120) bonded thereto. The plurality of inserts (120) include cutting surfaces (122) at different axial and radial positions relative to the axis (112) of the material removal tool (100). Cutting surfaces (122) at different axial and radial positions are arranged at different angles to the axis (112), and at least one cutting surface (122) on at least one insert is at an angle of about 45 degrees relative to the axis (112). Cutting surfaces (122) can be located on one insert-type or different insert-types and can have different combinations of cutting surfaces (122). When arranged circumferentially on the insert housing (106), a N-effective material removal tool (100) is formed. Methods of machining using the N-effective material removal tool (100) are also disclosed.
