Definitions
- the present invention relates to a cubic boron nitride sintered body and a cutting tool.
- a cubic boron nitride sintered body (hereinafter sometimes abbreviated as a cBN sintered body) has excellent wear resistance, and is used, for example, as a cutting tool, and in particular, a sintered alloy that is cast iron or a difficult-to-cut material. It is widely used for processing.
- a cBN sintered body that includes a cubic boron nitride (cBN) phase and a binder phase containing W, Co, and Al, and contains B 6 Co 21 W 2 as a binder phase in a predetermined ratio.
- Patent Document 2 discloses a cBN sintered body containing cBN particles of 80% by weight or more and adding Al as the binder phase with a content ratio exceeding 50% by weight together with Co.
- the cubic boron nitride sintered body of this embodiment is a cubic boron nitride sintered body containing 85 to 97% by volume of cubic boron nitride particles and 3 to 15% by volume of a binder phase.
- the Al content in the cubic boron nitride sintered body is 0.1 to 5% by mass, the ratio of the Co content to the Al content is 3 to 40 in terms of mass ratio (Co / Al), and Al 3 It has B 6 Co 20 .
- the adhesion with the cubic boron nitride particles of the binder phase is improved, the detachment of the cubic boron nitride particles is suppressed, and the wear resistance is high.
- this cubic boron nitride sintered body is used for the cutting edge portion of a cutting tool, a cutting tool having high wear resistance and a longer life can be provided.
- the cubic boron nitride sintered body contains 85 to 97% by volume of cubic boron nitride particles (cBN particles) and 3 to 15% by volume of a binder phase.
- the Al content is 0.1 to 5 mass%, the ratio of the Co content to the Al content is 3 to 40 by mass ratio (Co / Al), and Al 3 B 6 Co 20 is included.
- the cBN sintered body of the present embodiment has improved adhesion with the cBN particles of the binder phase, suppresses the grain separation of the cBN particles, and has high wear resistance. Therefore, the cutting tool having the cBN sintered body of the present embodiment in the cutting edge portion has high wear resistance, and can be used for cutting for a long time. Further, since the specific resistance of the cBN sintered body is low, wire electric discharge machining is possible. Therefore, it is possible to produce a cutting tool that is easy to process.
- the amount of cBN particles is less than 85% by volume or the amount of the binder phase is more than 15% by volume, the hardness of the cBN sintered body is lowered and the wear resistance is lowered. If the amount of cBN particles is more than 97% by volume or the amount of the binder phase is less than 3% by volume, the adhesion force of the binder phase, that is, the holding power of the cBN particles is reduced, and the cBN particles are more crushed, and the resistance of the cBN sintered body is increased. Abrasion is reduced.
- the volume ratio of the cBN particles and the binder phase of the cBN sintered body is determined by measuring the area ratio of the cBN particles and the binder phase in the cross-sectional photograph of the cBN sintered body, and calculating the two-dimensional area ratio as the three-dimensional.
- the volume ratio of the cBN particles and the binder phase is assumed to be the same as the volume ratio.
- the average value is calculated by measuring at three or more locations.
- a desirable content ratio of the cBN particles is 90 to 96% by volume.
- the Al content in the cBN sintered body is less than 0.1% by mass, Al 3 B 6 Co 20 does not exist, the adhesive strength of the binder phase decreases, and the wear resistance of the sintered body Decreases.
- the Al content is more than 5% by mass, wire electric discharge machining becomes difficult. If the ratio of Co content to Al content is lower than 3 by mass ratio (Co / Al), Al 3 B 6 Co 20 does not exist and wire electric discharge machining becomes difficult. If the ratio of Co content to Al content is higher than 40 by mass ratio (Co / Al), the adhesiveness of the binder phase is lowered and the wear resistance of the cBN sintered body is deteriorated.
- a desirable range of the mass ratio (Co / Al) is 5 to 30.
