Abstract

Official abstract text for this publication.

A mirror finishing method for forming a mirror surface on a workpiece with a mirror finishing tool including a conically shaped cutting tool made of polycrystalline diamond or cubic boron nitride that is attached to a distal end of a shank, performs mirror polishing by abutting a conical surface of the cutting tool against a machined surface of the workpiece with the shank tilted with respect to the machined surface of the workpiece.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for producing a mirror finishing tool, comprising the steps of: tilting a cutting tool attached to a distal end of a shank of the mirror finishing tool, with respect to a direction in which a wire electrode of a wire electrical discharge machine extends, the cutting tool made of polycrystalline diamond or cubic boron nitride; and machining the cutting tool into a conical shape by the wire electrical discharge machine while axially turning the cutting tool, wherein in the step of machining the cutting tool, a discharge condition between the wire electrode and the cutting tool is changed during one revolution of the cutting tool to create an irregular surface having no isotropy.
