By including one or more types of each of the wS3 group consisting of i, it is suitable for intermittent cutting, high feed, milling, etc. for highly hard work materials.
以下１本発明複合切削体における一実施例について、図
を参照して説明する。An embodiment of the composite cutting body of the present invention will be described below with reference to the drawings.
第１図において、（１）は、本発明に係る複合切削体で

び超硬合金の基板（３）からなる。In FIG. 1, (1) is a composite cutting body according to the present invention, which is composed of a cubic polycrystalline sintered body (2) of boron nitride or the like and a cemented carbide substrate (3).

ルツ形の窒化硼素またはこの一部をダイヤモンドで置換
したものが結合材とともに超高圧高温下で、焼結される
が、この焼結時には、前記基板（３）上に固着される。This polycrystalline sintered body (2) is produced by sintering cubic and/or wurtzoid boron nitride or a part of it with diamond together with a binder under ultra-high pressure and high temperature. Sometimes it is fixed on the substrate (3).
この場合、基板（３）は、焼結済のものが適用され、例

、ダイヤモンドが１５％をこえると、熱的に弱くなり、
鋼、鋳鉄などの切削に不向きとなるからである。In the first invention, the cubic crystal type and/or Wurtz type boron nitride is contained in an amount of 70% based on the total amount of the polycrystalline sintered body (2).
~95%, and the remainder serves as a binder for metal components. Further, a part of boron nitride is replaced with diamond in the second invention. Based on the results of various cutting tests, the amount of substitution is preferably 15% or less relative to boron nitride. This is because when the diamond content exceeds 15%, it becomes thermally weak.
This is because it is not suitable for cutting steel, cast iron, etc.

結合材の結合強度を高める。The binder ranges from 5 to 30%, but Nb and MO
a first group consisting of Ni, Co and Fe, a third group consisting of An and Si, and one or more types are selected from each group. In this case, it is necessary that the components of the first group account for 50% or less of the total amount of the binder. This is because the components of the first group increase the toughness and high-temperature strength of the binder, but if they are present in too large a quantity, only the metallic properties become stronger, and conversely the high-temperature strength of the binder decreases. Moreover, the components of the second group and the third group tend to alloy or form intermetallic compounds, so that the hardness increases, but on the other hand, it becomes brittle. Furthermore, the second
The components of the group and the third group improve the wettability of the surface of CBN and WBN. Therefore, as mentioned above, the ingredients of the first group are added to the ingredients of the second group and the third group,
Increases the bond strength of the bonding material.

圧方式、ピストンシリンダ一方式およびベルト装置など
の超高圧発生装置により得られるものである。The ultra-high pressure and high temperature state is usually obtained by an ultra-high pressure generating device such as a four-way pressurization system, a six-way pressurization system, a piston/cylinder one-way system, or a belt device.
