この発明は、高圧相型窒化ホウ素焼結体やダイヤモンド
焼結体等の硬質焼結体を切刃に有する切削工具に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cutting tool having a cutting edge made of a hard sintered body such as a high-pressure phase type boron nitride sintered body or a diamond sintered body.
従来、高硬度材や難削材加工用の工具として、第４図乃
至第６図に示すように、高圧相型窒化ホウ素焼結体やダ
イヤモンド焼結体等の硬質焼結体を接合して切刃となし
たスローアウェイチップや溝入れバイト等の切削工具が
知られている。Conventionally, tools for machining high-hardness materials and difficult-to-cut materials have been used to join hard sintered bodies such as high-pressure phase boron nitride sintered bodies and diamond sintered bodies, as shown in Figures 4 to 6. Cutting tools such as indexable inserts and grooving bits that serve as cutting edges are known.
この工具は、図に示すように、加工形態に合わせて形成

片１１をろう付等により接合し、その切刃片１１の上面
と側面との交差稜を切刃にしたもので、切刃片１１は通
常焼結炭化物１２を介してシャンク１０のコーナ一部に
接合される。As shown in the figure, a cutting blade piece 11 made of a hard sintered body is joined by brazing or the like to the top surface of a shank 10 that is formed according to the processing form, and the top surface of the cutting blade piece 11 and The ridge that intersects with the side surface is used as a cutting edge, and the cutting edge piece 11 is usually joined to a part of the corner of the shank 10 via a sintered carbide 12.
このシャンク１０の材料には、切刃片１１より軟質で靭
性の高い材質が用いられ、スローアウェイチップや溝入
れバイトの場合、一般に超硬合金が用いられる。The shank 10 is made of a material that is softer and has higher toughness than the cutting edge piece 11, and in the case of indexable inserts and grooving bits, cemented carbide is generally used.
ところで、上記切削工具において、切刃片１１は、一般

１１の上面は凹凸の無い平坦な面になっており、実際に
切削加工を行なった場合、切屑が長く伸び、工具切刃や
加工物にからみ付いて、切刃の破損や加工物表面を傷付
けるという不具合がある。Incidentally, in the above-mentioned cutting tool, the cutting edge piece 11 is generally formed by cutting into a predetermined shape from a disk-shaped blank made of a relatively large hard sintered body. For this reason, the upper surface of the cutting blade piece 11 is a flat surface with no irregularities, and when actual cutting is performed, chips will elongate and become entangled with the tool cutting edge or the workpiece, causing damage to the cutting edge. There is also the problem of damaging the surface of the workpiece.
一方、このような不具合に対処するため、第７図（ａ）
（ｂ）に示すように、切刃片１１の上面にブレーカ溝
１３を設けた工具も実用化されている。On the other hand, in order to deal with such a problem, as shown in Fig. 7(a)
As shown in (b), a tool in which a breaker groove 13 is provided on the upper surface of the cutting edge piece 11 has also been put into practical use.
しかし、硬質焼結体は、高硬度で加工特性が悪いために
、研削加工等でブレーカ溝を形成するのは時間がかかり
、実際には、加工費の高い研削加工や放電加工により溝
の形成が行なわれている。However, since hard sintered bodies have high hardness and poor machining properties, it takes time to form breaker grooves by grinding, etc., and in reality, grooves are formed by grinding or electrical discharge machining, which is expensive. is being carried out.
しかし、硬質焼結体はそれ自体として非常に高価であり
、この種の工具にさらに研削や放電加工を施した場合、
製造コストが上昇し、工具価格が高くなる不具合がある
。However, the hard sintered body itself is very expensive, and if this type of tool is further subjected to grinding or electrical discharge machining,
There are problems that increase manufacturing costs and tool prices.
さらに、加工特性の悪さから、ブレーカ形状が溝や段な
どの簡単な形状にならざるを得す、最適なブレーカ形状
を形成できない問題もある。Furthermore, due to poor machining characteristics, the breaker shape has to be a simple shape such as a groove or a step, and there is also the problem that an optimal breaker shape cannot be formed.
この発明は、上記の問題に鑑みてなされたもので、工具
価格の上昇をな（して、最適なブレーカを具備しうる切
削工具を提供することを目的としている。This invention was made in view of the above problems, and aims to provide a cutting tool that can be equipped with an optimal breaker while reducing the cost of the tool.
上記の問題を解決するため、この発明は、硬質焼結体の
切刃片を、切刃近辺にのみ沿う形状となし、その切刃片
の上面に連なるシャンクの上面に、チップブレーカを設
けたものである。In order to solve the above problem, the present invention has a cutting edge piece of a hard sintered body shaped only to the vicinity of the cutting edge, and a chip breaker is provided on the upper surface of the shank that is connected to the upper surface of the cutting edge piece. It is something.

自体のろう付性の悪さを補なっているのである。本発明
で用いるシャンクとしては、加工性では硬質焼結体より
はるかに優れている超硬合金を用いることが望ましい。Examples of the hard sintered body in the present invention include diamond sintered bodies and hard sintered bodies formed by sintering high-pressure phase boron nitride such as cubic boron nitride and wurtzite boron nitride. usually,
Since these sintered bodies have poor brazing properties, they have a structure in which these hard sintered bodies are bonded to a cemented carbide. That is, by brazing on the cemented carbide surface, the poor brazing properties of the hard sintered body itself are compensated for. As the shank used in the present invention, it is desirable to use cemented carbide, which is far superior in workability to hard sintered bodies.
本発明の特徴は、第７図に示すような形状をとらず、あ

体には凹凸加工を施さない構造とすることによって、プ
レーカー自体の形成費用を著しく低減したものである。The feature of the present invention is that, instead of taking the shape shown in Fig. 7, the shank part is subjected to complicated processing, and the hard sintered body itself has a structure in which no uneven processing is applied. This significantly reduces the cost of forming itself.
従来、第４図、第５図、第６図に示す構造があるだけに
、ここを出発点として、ブレーカーを設けることを考え

の１７５の費用でブレーカ−を設けることを可能とする
。Conventionally, there were structures shown in Figures 4, 5, and 6, and in order to consider installing a breaker using this as a starting point, a breaker as shown in Figure 7 was first invented. be. The inventors broke away from such preconceptions and reconsidered the structure of the hard sintered tool, thereby making it possible to provide a breaker at a cost of 175 yen.

部品としているが、当然のことながら、シャンクと一体
であっても何等問題はない。In order to manufacture the breaker of the present invention as shown in FIG. 1, a shank 1 having a protrusion is prepared in advance. This is a method widely used for cemented carbide tools. This shank 1 is further provided with a recess 3, and a cutting blade piece 2 made of a hard sintered body is brazed and joined to the recess 3. Further, in FIG. 3, the breaker portion 1a is shown as one component, but it goes without saying that there is no problem even if the breaker portion 1a is integrated with the shank.

によって、切屑を適切に分断することができる。The present invention is particularly effective for a grooving tool as shown in FIG. In other words, if a grooving tool does not have a breaker, there is a problem in which continuous chips are ejected toward the front and wrap around the workpiece, etc., but by using the structure shown in Figure 3, the chips can be removed. Can be divided appropriately.
以下、この発明の実施例を添付図面に基づいて説明する
。Embodiments of the present invention will be described below with reference to the accompanying drawings.

等の工具寿命を得ることができる。In the cutting tool configured as described above, when the chips generated by the cutting blade flow on the rake surfaces of the upper surface of the cutting blade piece 2 and the upper surface of the shank 1, they come into contact with the protrusion 4.5 on the upper surface of the shank. A breaking force is applied, causing deformation or separation. In this case, all the cutting edges used are surrounded by the cutting edge piece 2 made of hard sintered body, so there is no decrease in wear resistance, and unlike the conventional structure, a part of the corner is entirely covered with the cutting edge piece. It is possible to obtain a tool life that is almost the same as that of the previous one.

A recess 3' is formed, and a breaker groove 7 is provided in this recess 3'. This breaker groove 7 may be formed before joining the cutting blade piece 2' to the recess 3', but if the breaker shape is a simple groove as described above, the cutting blade piece 2' can be formed in the recess. 3'
Even if the material is formed after being bonded to the material and before machining, electrical discharge machining, or sintering, inexpensive molding can be performed.

Join by brazing. The breaker member 1a is fitted between the cutting blade piece 2'' attached as described above and the rear surface of the recess 3'', and is fixed to the support member 1b by brazing.

゛In order to examine the performance of the cutting tool according to the present invention, a comparative test with a conventional example was conducted. The target tools are the grooving tool shown in Fig. 3 and the conventional grooving tool shown in Fig. 5.The material of each shank and breaker member is cemented carbide, and the cutting edge is made of cubic boron nitride. It was formed from a high-pressure phase type boron nitride sintered body containing 60% volume.

In the conventional cutting tool shown in FIG. 5, there was a phenomenon in which the chips were elongated and wrapped around the workpiece during cutting, but in the cutting tool of the present invention shown in FIG. 3, the chips were thinly wound by the breaker member 1a. Curled and parted.

It has the advantage of being able to form a breaker.
