Abstract

Official abstract text for this publication.

A mirror finishing method for mirror-finishing a workpiece includes: a step of performing a first machining operation with a first tool which has a cylindrical portion made of polycrystalline diamond or cubic boron nitride at the tip of a shank thereof and further has a cutting edge formed by forming a linear groove on the cylindrical portion; and a step of, after the first machining operation has been performed, performing a second machining operation with a second tool which has a cylindrical portion made of polycrystalline diamond or cubic boron nitride at the tip of a shank thereof with no cutting edge on the cylindrical portion.

First claim

Opening claim text (preview).

What is claimed is: 1. A mirror finishing method for mirror-finishing a metal workpiece, comprising: a step of performing a first machining operation with a first tool, wherein the first tool has a cylindrical portion made of polycrystalline diamond or cubic boron nitride at a tip of a shank thereof and further has a cutting edge formed by forming a linear groove on the cylindrical portion; and a step of, after the first machining operation has been performed, performing a second machining operation with a second tool, wherein the second tool has a cylindrical portion made of polycrystalline diamond or cubic boron nitride at a tip of a shank thereof with no cutting edge on the cylindrical portion. 2. The mirror finishing method according to claim 1 , further comprising a step of, before the first machining operation, performing a third machining operation with a third tool, wherein the third tool has a body made of cemented carbide at a tip of a shank thereof and further has a cutting edge on the body. 3. The mirror finishing method according to claim 1 , wherein the linear groove is a linear recess defined in an outer surface of the cylindrical portion.
