Abstract

Official abstract text for this publication.

In a pilot hole of a workpiece made of a difficult-to-cut cast iron, a cutting tool having a leading end to which a cutting insert is attached is inserted to cut the surface of the wall of the pilot hole. At this time, the cutting tool rotates about an axis (α) and also revolves about another axis (β), so that contouring is performed on the workpiece by the tool. The cutting insert is formed of a sintered body having a CBN content of not less than 85% by volume, and the cutting insert has a thermal conductivity of not less than 100 W/(mK).

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for processing a difficult-to-cut cast iron, comprising the steps of: preparing a workpiece made of a difficult-to-cut cast iron; and cutting said workpiece using a cutting tool having a cutting insert, in said step of cutting said workpiece, said cutting tool revolving while rotating to allow said cutting insert to intermittently contact said workpiece, said cutting insert being formed of a sintered body having a CBN content of not less…
