    摘要: A sintered material containing high-pressure phase-type boron nitride and a binder is provided. The high-pressure phase-type boron nitride is contained in an amount of from 50% to 78% by volume, and the balance is a binder phase. The binder phase comprises at least one selected from the group consisting of nitride, carbide, carbonitride, and boride of Ti, nitride, boride and oxide of Al, carbide and boride of W, nitride, carbide, carbonitride and boride of Co, and carbide and boride of Ni, or a mutual solid solution thereof. The binder phase forms a binder phase which is continuous in a sintered material texture. The weight of metal components Al, W, Co and Ni which are present as compounds in the sintered material is from 3% to 20% based on the sintered material. The sintered material is excellent in crater resistance and capable of realizing a long tool life, even under the condition that the temperature of the cutting edge becomes high and the impact is large, as in high-speed interrupted cutting of hardened steel where the cutting speed V becomes at least 150 m/min.

    摘要: A method of cutting hardened steel using a cBN sintered tool which can improve the surface roughness while maintaining high dimensional accuracy. The upper limit of the tool feed rate is set at such a value that a theoretical surface roughness calculated from the feed rate is between 2/3 and 1/1000 of the target surface roughness. The amount of change of the feed rate between the upper and lower limits of the tool feed rate is set to be between 0.002 and 0.05 mm/rev, and the amount of every feed rate change is set not to be equal to the original feed rate multiplied by an integer. The feed rate is changed forcibly for every number of workpieces for which the total cutting length is between 10 and 1000 meters.

    摘要: In a hard sintered cutting tool, the tool life can be further increased. In this hard sintered body cutting tool, a rake face of an edge portion is formed by a major surface of a first sintered body layer containing at least 80 percent by volume and less than 98 percent by volume of diamond, while a flank of the edge portion is formed by a second sintered body layer containing at least 30 percent by volume and less than 75 percent by volume of cubic boron nitride (CBN). The first sintered body layer is formed to have a thickness of at least 0.02 mm and less than 0.1 mm, and to be in a thickness ratio of at least 1:5 to the second sintered body layer. Thus, chipping resistance of the rake face is improved by the first sintered body layer, while wear resistance of the flank is improved by the second sintered body layer. As a result, it is possible to suppress progress of local wear and chipping, whereby the life of the cutting tool is increased as compared with the prior art.
