SURFACE COATED CUTTING TOOL AND MANUFACTURING METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2019/176202
Kind Code:
A1
Abstract:
This surface coated cutting tool comprises base material and a coating that covers the base material. The base material includes a cutting face and a flank. The coating includes a TiCN layer. The TiCN layer has a (422) orientation in a region d1 of the cutting face, and a (311) orientation in a region d2 of the flank. In a case where the cutting face and the flank are connected through a tip surface, the region d1 is a region disposed between a boundary line of the cutting face and the tip surface and an imaginary line D1 spaced 500μm along the cutting face from an imaginary ridgeline, and the region d2 is a region disposed between a boundary line of the flank and the tip surface and an imaginary line D2 spaced 500μm along the flank from the imaginary ridgeline. In a case where the cutting face and the flank are connected through a ridgeline, the region d1 is a region disposed between the ridgeline and an imaginary line D1 spaced 500μm along the cutting face from the ridgeline, and the region d2 is a region disposed between the ridgeline and an imaginary line D2 spaced 500μm along the flank from the ridgeline.
