Multi-Effective Material Removal Tool
First Claim
1. A material removal tool, comprising:
- a mating structure for attaching the material removal tool to a spindle of a machine tool;
a reduced diameter circumferential insert housing including a plurality of inserts bonded thereto;
a holder; and
a reamer positioned in the holder and longitudinally extending therefrom along an axis of the material removal tool,wherein the mating structure, the reduced diameter circumferential insert housing, the holder and the reamer are arranged axially along the axis with the mating structure at a rearwardmost end and the reamer at the forwardmost end,wherein the plurality of inserts include cutting surfaces at different axial positions relative to the axis of the material removal tool and at different radial positions relative to the axis of the material removal tool,wherein the cutting surfaces at different axial and radial positions are arranged at different angles to the axis, andwherein at least one cutting surface on at least one insert is at an angle of about 45 degree relative to the axis.

Abstract
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) is also disclosed.
