本発Ｆ３Ａは工具における超硬合金の固着方法に関し、
ホーンに取付けられる加ニガイド用のガイド片のｊ（Ｘ
（りの際などに実施される。[Detailed description of the invention] The present invention F3A relates to a method for fixing cemented carbide in a tool,
J (X) of the guide piece for the crab guide attached to the horn
(It is carried out at times such as weddings.
通常、超硬合金工具ｗ４は、バイト、フライス用工具に
使用されるが、このような形式の工具では刃物を特定の
形状に形成した焼結物（チップ）とし、これｆ！：機械
的に締め付けて工具主体に取付る方式を採用している。Normally, the cemented carbide tool w4 is used as a cutting tool or a milling tool, but in these types of tools, the blade is a sintered product (chip) formed into a specific shape, and this f! : Adopts a method that is mechanically tightened and attached to the main tool.
ところが、このフラング方式を採用できないものではロ
ク付等の方法で工具主体に固着する方法を採用する。However, in cases where this flang method cannot be used, a method such as locking is used to fix the tool to the main body of the tool.
たとえば、ホーニング用の工具（ホーン）に収付けられ
る加ニガイドにはこのロク付方法が採用されている。For example, this locking method is used for a knife guide that is housed in a honing tool (horn).
このホーンは、ホーニング盤の主軸に取付けられて使用
されるもので、回転と軸方向の動きが付与された状態で
被加工部としての穴に対応せしめられ、加工が進行する
。This horn is used by being attached to the main shaft of a honing machine, and the horn is rotated and moved in the axial direction while being brought into contact with a hole as a part to be machined, and machining progresses.
この為、工具主体の加工部には第４，５図の如く、複数

具主体が被加工面に抵触することがあることから、通常
は工具主体（２）よりも硬度の高い超硬合金工具鋼から
なるガイド片（３）が上記方法で添設される。This is to prevent the tool main body (2) from wobbling during machining, and since the tool main body may come into contact with the workpiece surface during the initial stage of honing, usually the tool main body (2) ) is attached by the above method.

ド片（３）は直接工具主体（２）にロウ付けできない。Fixing by brazing has a high melting temperature, and
The guide piece (3) made of the above material cannot be brazed directly to the tool main body (2) because it is necessary to heat both of the K1-1 joining members to a high temperature in order to achieve reliable brazing.
高温度に加熱すると工具生体（２）及びガイド片（３）

), and then the deformation caused when brazing the ID piece (3) and the auxiliary stand c31) is shaped into a predetermined shape.
After re-machining with high precision, both of these assemblies were attached to the groove 011 of the main body of the tool (2) by low-temperature brazing.

For the installation of the auxiliary stand (311 force Kgo
In addition, brazing work and guide pieces (3
) and the auxiliary stand 011 require refinishing.
Productivity is extremely low.
上記のような手間のかかる工程を要するのは。It requires a time-consuming process like the one mentioned above.
超硬合金工具鋼は低温でのロウ付、ハンダ付性能が悪く
、その捷ま工具主体に同右できないからである。This is because cemented carbide tool steel has poor brazing and soldering performance at low temperatures, and cannot be used as a main tool for cutting tools.
本発＃４Ｖｉ、超硬合金ｍを炭素鋼からなる工具主体等

ンダ付性能を改善することをその課題とする。The purpose of this project is to improve the soldering performance of cemented carbide tool steel so that #4Vi and cemented carbide m can be placed directly on a tool mainly made of carbon steel.

め銅メツキ皮膜とスズメッキ皮膜を形成して、これを工
具本体等の固着対象物にハンダ付けすることである。The technical means of the present invention for solving the above problem is to form a copper plating film and a tin plating film on objects to be fixed such as blades and guide pieces made of cemented carbide tool steel in advance, and apply them to the tool body, etc. Soldering to a fixed object.
本発明の上記技術手段は次のように作用する。The above technical means of the present invention operates as follows.
超硬合金工具鋼は炭素鋼等にくらべてパンダが付きにく
い性質を持つが、ハング付性能の材質のものＫは付き易
い。Cemented carbide tool steel has the property of being less susceptible to pandering than carbon steel, etc., but K, which is made of a material with hangable properties, is more likely to be pandered.
上記技術的手段によれば、超硬合金鋼からなる刃物、ガ
イド片等には最外層にスズメッキ皮膜があることから、
炭素鋼からなる工ｉ主体と前記表面処理を施したガイド
片等とは容易にハンダ付けされるとさとなり、しかも、
ハンダの渦流れがよく、確実にハンダ付けできる。According to the above technical means, since the blades, guide pieces, etc. made of cemented carbide steel have a tin plating film on the outermost layer,
The main body made of carbon steel and the surface-treated guide pieces can be easily soldered together, and
The solder flows well and can be soldered reliably.
１だ、ハンダ付けの場合には、ハンダの溶融温度が低い
ことから、ハンダ付けの際のガイド片等の加熱温度もほ
とんどなく、加熱による変形、ひずみ等も生じない。1. In the case of soldering, since the melting temperature of the solder is low, there is almost no heating temperature for the guide pieces, etc. during soldering, and no deformation or distortion occurs due to heating.
木発ｌ３Ｊ１け上記構成であるから、次の特有の効果を
有する。Since the Kibatsu 13J1 has the above configuration, it has the following unique effects.
超硬合金工具鋼からなる刃物、ガイド片等の被固着物が
そのま捷変形することなく固着対象にハンダ（Ｊけでき
るから、従来におけるような中間の再加工工程が不要と
なる。Since solder can be applied to objects to be fixed, such as blades and guide pieces made of cemented carbide tool steel, without bending or deforming, there is no need for intermediate reworking steps as in the past.
また、前記被固着物の表面がハンダと同様の材質（スズ
）で構成されているから、ハンダによる溶着性が良く、
シかも、渦流れが良いことから、簡単且確実にハンダ刊
けできると共に固着強度も十分なものとなる。In addition, since the surface of the object to be adhered is made of the same material (tin) as the solder, it has good weldability with the solder.
Moreover, since the vortex flow is good, it is possible to solder easily and reliably, and the adhesion strength is also sufficient.
さらに、スズメッキ皮膜は銅メツ、キ皮膜を介して母材
としての被固着物表面に形成されるから、これらＩ３１
膜の旬着強度が高く、スズメッキ皮膜を直接被固着物表
面に形成したものｔハンダイー１けする場合にくらべて
固着強度が向上する。Furthermore, since the tin plating film is formed on the surface of the object to be adhered to as the base material through the copper metal and tin films, these I31
The adhesion strength of the film is high, and when the tin plating film is directly formed on the surface of the object to be adhered, the adhesion strength is improved compared to when the tin plating film is directly applied to the surface of the object to be adhered.
以下、本発明の実施例を図面に基ついて説明する。Embodiments of the present invention will be described below with reference to the drawings.
この実施例は、ホーンのガイド片（３）の固着の際に実
施したもので、放射状に配設される砥石（１）。This example was carried out when fixing the guide pieces (3) of the horn, and the grindstones (1) are arranged radially.
（１）相互の間にこのガイド片（３）が固着される。(1) The guide pieces (3) are fixed between them.
この為、工具主体（２）の前記砥石を配設する部分には

ダ付けされる。For this reason, the part of the main body of the tool (2) where the grindstone is arranged has a concave part a (221) for fixing the guide piece (3).
are provided, and guide pieces (3) are individually soldered to the recesses.
このガイド片は超硬合金工具鋼からなり、既述したよう
に予め銅メッキ、スズメッキ処理が施されている。（第
３図参照）
ここで、銅メッキ皮ｙ！儲はスズメッキ皮膜曽の付着力
を高めるためのもので、前記材質のガイド片（３）に直
接スズメッキを施す場合にくらべて一段店付着力が高く
なる。This guide piece is made of cemented carbide tool steel, and has been previously copper-plated and tin-plated as described above. (See Figure 3) Here, the copper plated skin y! The coating is intended to increase the adhesion of the tin plating film, and the adhesion is much higher than that in the case where the guide piece (3) made of the above material is directly plated with tin.
尚、この銅メツキ皮膜の膜厚はす〜ｌυミクロン程度以
上であればスズメッキ皮膜の付着力が十分であシ、他方
、スズメッキ皮膜国の膜厚はに〜１０ミクロン程度以上
にしておけば、ハンダ付は工程における作業性かよく、
且、固着力も十分なものとなった。It should be noted that if the thickness of this copper plating film is about lυ microns or more, the adhesion of the tin plating film is sufficient.On the other hand, if the film thickness of the tin plating film is about 10 microns or more, Soldering is easy to work with in the process,
Moreover, the adhesion force was also sufficient.
上記のように、表面処理されたガイド片（３）を。The guide piece (3) has been surface treated as described above.
工具主体（２）の凹陥部（２）に嵌め込んで、ハンダ付
けすると、ハンダが溶融して工具主体（２）にガイド片
（３）が固着される。When the guide piece (3) is fitted into the recess (2) of the tool main body (2) and soldered, the solder melts and the guide piece (3) is fixed to the tool main body (2).
上記実施例の場合は、ガイド片（３）Ｋのみ表面処理を
施したが、工具主体（２）の凹陥部に等、固着対象部分
を同様に表面処理（銅メッキ＋スズメッキ）しておいて
もよく、この場合には一層ハンダ付けがし易すくなる。In the case of the above example, only the guide piece (3) K was surface-treated, but the parts to be fixed, such as the recessed parts of the tool body (2), were also surface-treated (copper plating + tin plating). In this case, soldering becomes even easier.

い。In this case, since a grindstone drive mechanism is incorporated in a tool such as a horn, inconveniences due to the formation of the plating film in the grindstone accommodation hole 5 (4) etc., that is, malfunction may occur. , you just need to apply a koking.
以上の実施例では、ホーンに固着されるガイド片（３）
