【発明の詳細な説明】
(イ) 技術分野
この発明は特に耐摩耗性と靭性にすぐれた複合
工具およびその製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION (a) Technical field The present invention particularly relates to a composite tool with excellent wear resistance and toughness, and a method for manufacturing the same.
(ロ) 技術背景
深穴加工のように、工具保持部と加工部との距
離が長い場合、先端の加工部のみに超硬合金を用
い、シヤンクとして鋼を用いると、鋼部の剛性不
足により、寸法精度が悪いという問題がある。(b) Technical background When the distance between the tool holding part and the machining part is long, such as in deep hole machining, if cemented carbide is used only for the tip machining part and steel is used for the shank, the steel part will not have sufficient rigidity. , there is a problem of poor dimensional accuracy.
しかして全体を超硬合金とすると、高価になる
とか、あるいはシヤンク部の強度が不足して折れ
てしまうとかの問題が残されている。 However, if the entire structure is made of cemented carbide, there are still problems that it will be expensive or that the shank part will not have enough strength and will break.
(ハ) 発明の開示
この発明は、複合工具のシヤンク部に折損に強
い超硬合金、即ち結合金属量の多い超硬合金を用
いることによつて、上記した欠点を解消しようと
するものである。(C) Disclosure of the invention This invention attempts to solve the above-mentioned drawbacks by using a breakage-resistant cemented carbide, that is, a cemented carbide with a large amount of bonded metal, in the shank portion of a composite tool. .
結合金属量の多い超硬合金を用いることは、折
損に対する抵抗を大幅に増すので、安価な例えば
若干不純物が多いようなWCを用いることも可能
となるのである。 Using a cemented carbide with a large amount of bonded metal greatly increases the resistance to breakage, making it possible to use cheaper WC, for example, which has a slightly higher amount of impurities.
従来上記に述べたと同じ考えのもとに、色々と
検討がなされているが、何れも全面的に問題点を
解消するには至つていない。 Various studies have been made based on the same idea as mentioned above, but none of them has been able to completely solve the problems.
誰でもが考える改良法として鑞付け法がある。
この方法は工具にかかる力が小さい時には可能で
あつても、一般には鑞付け面積に制限があるので
接合強度が不十分である。 The brazing method is an improvement method that everyone thinks about.
Although this method is possible when the force applied to the tool is small, the joint strength is generally insufficient due to the limited brazing area.
また金属の場合、接合方法の１つとして摩擦溶
接が用いられている。しかしながら金属といつて
も超硬合金同志の場合、これは原理的に不可能で
ある。 Furthermore, in the case of metals, friction welding is used as one of the joining methods. However, in the case of metals and cemented carbide, this is impossible in principle.
本発明者らは、上記の点から種々検討の結果、
接合しようとする超硬合金の間に金属あるいは合
金の板を挾むことを考えた。そして金属あるいは
合金の板を予め超硬合金の接合しようとする端面
に接合しておくと極めて好ましい接合を与えるこ
とを見出したものである。 As a result of various studies from the above points, the present inventors found that
We considered sandwiching a metal or alloy plate between the cemented carbide to be joined. The inventors have also discovered that an extremely preferable bond can be obtained by bonding a metal or alloy plate to the end face of the cemented carbide to be bonded in advance.
以下この発明を図面に基づいて説明する。 The present invention will be explained below based on the drawings.
超硬合金製のチツプを該チツプより体積の大き
い超硬合金製の支持体に接合するに当つて、第１
図の如く、チツプ１と支持体２の間に接合部材３
としてNi，Coまたはこれらの合金の板を挾み、
チツプまたは支持体あるいは双方を高速回転させ
る。この時チツプとNi，Coまたはこれらの合金
あるいはNi，Coまたはこれらの合金と支持体の
間で摩擦熱が生じ、Ni，Coまたはこれらの合金
が軟化して流動するため、チツプと支持体の接合
部全体にわたつて均一に接合させることが可能で
ある。また、第２図に示すように、超硬合金チツ
プ１の端面にNi，Coまたはこれらの合金を接合
部材３として接合させておき、超硬合金製支持体
（シヤンク）２に予めNi，Coまたはこれらの合金
を接合部材３′として接合したものを摩擦溶接す
ることはより望ましい。 When joining a cemented carbide chip to a cemented carbide support whose volume is larger than that of the chip, the first step is to
As shown in the figure, a joining member 3 is placed between the chip 1 and the support 2.
Ni, Co or these alloy plates are sandwiched as
The chip and/or support are rotated at high speed. At this time, frictional heat is generated between the chip and Ni, Co, or their alloys, or between Ni, Co, or these alloys, and the support, and as the Ni, Co, or these alloys soften and flow, the chip and the support It is possible to uniformly join the entire joint. Further, as shown in FIG. 2, Ni, Co, or an alloy thereof is bonded to the end face of the cemented carbide chip 1 as a bonding member 3, and a cemented carbide support (shank) 2 is preliminarily bonded with Ni, Co, or an alloy thereof. Alternatively, it is more desirable to friction weld a joint member 3' made of these alloys.
この場合、チツプに接合するNi，Coまたはこ
れらの合金と、支持体（シヤンク）に接合する
Ni，Coまたはこれらの合金を同一のものとすれ
ば、非常によく接合する。 In this case, Ni, Co, or their alloys are bonded to the chip and the support (shank) is bonded to the chip.
If Ni, Co, or their alloys are the same, they will bond very well.
さらに、チツプもしくは支持体（シヤンク）の
どちらか一方にNi，Coまたはこれらの合金を接
合しておき、超硬合金との摩擦溶接も可能であ
る。 Furthermore, it is also possible to bond Ni, Co, or an alloy thereof to either the chip or the support (shank), and friction weld it to the cemented carbide.
この発明でチツプと支持体を接合する接合部材
としては、Ni，Coまたはこれらの合金が適して
いる。 In this invention, Ni, Co, or an alloy thereof is suitable as the joining member for joining the chip and the support.
CoまたはNiは接合すべき超硬合金の結合相と
して使用されており、接合時に接合強度を低下せ
しめるような冶金学的な欠陥を生じ難い点で好ま
しい。 Co or Ni is used as a binder phase for cemented carbide to be joined, and is preferred because it is unlikely to cause metallurgical defects that would reduce joint strength during joining.
また、この発明の複合工具の接合部には超硬合
金の結合材が均一に拡散しており、かつ空孔等の
欠陥は存在しないのである。 Furthermore, the cemented carbide binder is uniformly diffused in the joint of the composite tool of the present invention, and there are no defects such as holes.
特に接合部材としてNiまたはNi合金を用いた
場合は、接合時に超硬合金中の例えばWCや
（Mo，Ｗ）Ｃ等の炭化物が分解して接合部材の金
属と反応して有害な複合炭化物相が析出するよう
なことが少なく、極めて高強度な接合が可能であ
る。 In particular, when Ni or Ni alloy is used as a joining member, carbides such as WC and (Mo, W)C in the cemented carbide decompose during joining and react with the metal of the joining member, forming a harmful composite carbide phase. There is little chance of precipitation of particles, and extremely high-strength bonding is possible.
接合部材としてのNi，Coまたはこれらの合金
よりなる接合層の厚さは１mm以下が好ましい。こ
れは厚さが１mmを超えると、Ni，Coまたはこれ
らの合金よりなる接合層の耐摩耗性が劣つて好ま
しくないためである。 The thickness of the bonding layer made of Ni, Co, or an alloy thereof as a bonding member is preferably 1 mm or less. This is because if the thickness exceeds 1 mm, the wear resistance of the bonding layer made of Ni, Co, or an alloy thereof will be poor, which is not preferable.
この発明の複合工具の用途としては、長物のエ
ンドミル、ドリル、パンチなどがある。 Applications of the composite tool of the present invention include long end mills, drills, and punches.
これは、この発明では支持体（シヤンク）とし
て超硬合金を用いるので、鋼を用いたものに比べ
てはるかに剛性が高く、これら用途における高い
寸法精度を保持することができるためである。 This is because in this invention, since cemented carbide is used as the support (shank), the rigidity is much higher than that using steel, and high dimensional accuracy in these applications can be maintained.
以下、実施例によりその発明を詳細に説明す
る。 Hereinafter, the invention will be explained in detail with reference to Examples.
