摘要 |
A surface-covered CBN sintered body tool (1) includes a base material (2) formed with a cubic boron nitride (CBN) sintered body and a surface covering film (3) covering a surface of the base material (2), and has a nega-land (4) exposin g the CBN sintered body in at least a portion thereof and a flank (5) having the surfa ce covering film (3) formed thereon. With this, the surface-covered CBN sintered body to ol (1) having high defect resistance and wear resistance can be provided. The surfa ce covering film (3) preferably includes a nitride or a carbonitride of a compound including at least one element selected from the group consisting of Ti, Cr, Zr, and V and at least one element selected from the group consisting of Al, Si and B, or a nitride or a carbonitride of Ti. |
