Title: Cutting method in controlled environment
Inventor: TOBIOKA MASAAKI
IPC: B23P25/00
Filed: 1986-10-17
Abstract: PURPOSE:To enable the service life of a cutting tool to be extended when a workpiece material is cut by means of the cutting, tool, by limiting a content of oxygen to less than 2 volumetric % in the environment around a spot where the cutting tool makes contact with the workpiece material to be cut. CONSTITUTION:It is enough for the purpose of preventing oxidization from taking place during a cutting process to inhibit supply of oxygen into a portion where a cutting tool and a workpiece material make mutual contact. From view of such a standpoint, an oxygen content is limited to less than 2 volumetric % of the normal atmosphere, in the environment around a spot where the cutting tool and the workpiece material make mutual contact. Then, acid-proof property is remarkably enhanced for such a cutting tool as containing hard nitride as its hardness dispersion phase. Forthermore, no such an effect can be observed if the oxygen content is 2 volumetric % or more. Although many sorts of compound may be taken into account as hard nitride, silicon nitride or titanium nitride is considered preferable.
