部使用されているにとどまる。[Prior Art] This type of seed chip is made of various materials such as cemented carbide and ceramic for convenience in manufacturing and use. However, due to its ultra-hardness and high price, diamond has not become popular, and only some tools with cutting edges made of sintered diamond are used.
[発明が解決しようとする問題点]
単結晶ダイヤモンド切刃は、焼結ダイヤモンドや超硬合
金と比較し被削材が溶着しに<(、且つ極めて鋭利で、
精密切削に極めて秀れている。[Problems to be solved by the invention] Compared to sintered diamond and cemented carbide, single-crystal diamond cutting edges are less likely to weld the workpiece and are extremely sharp.
Extremely good at precision cutting.
然しその特性が秀れておりまた主として天然であるため
価格は焼結ダイヤモンドより更に高く、固定も力/メや
粉末冶金法によるためスローアウェイ型に使用されてい
ない。However, because it has excellent properties and is mainly natural, its price is higher than sintered diamond, and because it is fixed by force/mechanism or powder metallurgy, it is not used in indexable types.
[問題点を解決するための手段]
価格については、実用的なダイヤモンド切刃の大きさ形

出来た。[Means to solve the problem] Regarding the price, it is possible to obtain indexable inserts that are sufficient for industrial production by researching and improving the size and shape of a practical diamond cutting blade and the brazing method for fixing. done.
ダイヤモンドは1/10ct以下、好ましくは!/20
ct以下の切刃を、剛性の高い超硬合金台金の凹部にC
uAg系のろう材により強固に接合して得られる。Diamonds should be less than 1/10 carat, preferably! /20
ct or less cutting edge into the recess of the highly rigid cemented carbide base
Obtained by strong bonding using uAg-based brazing material.
[作用]
剛性の高い合金の四部に強固に固若されてなる!11結
品ダイヤモンド切刃は、l/20ct程度と小さくても

ろはなかった。また価格が引き下げられるのでスローア
ウェイとして充分な経済性を上げることが出来る。[Function] Made of four parts of highly rigid alloy! Although the diamond cutting blade is as small as 1/20ct, it is superior in accuracy, performance, and durability compared to cutting tools with large diamond cutting blades that are fixed to the shank by conventional caulking or powder metallurgy. There was no place to take as a course. In addition, since the price is reduced, sufficient economy can be achieved as a throw away.

げられた1大態で約1/20ctである。[Example] Figure 1A shows a front view and a side view of the chip of the present invention.
2 is a polygonal board base made of cemented carbide, 2 is a recess provided at the corner of the top surface, 3 is a cutting blade made of single crystal diamond, and FIG. 2 is a cutting blade showing four types of blade shapes of cutting blade 3. It is an enlarged view from the top. The cutting blade 3 is chemically bonded to the recess 2, and the scooping surface is finished by brazing so as to be formed by 100 or 0 faces of single crystal diamond. The finished size is approximately 1/20 ct.
化学的接合は、ダイヤモンドと化学的親和性をイTする
活性金属であるT++ Tap Nb+ Fe+ NI
+ Hrの何れかまたはその合金の介在下においてCu
−A g系ろう材によって行なわれる。Chemical bonding is performed using T++ Tap Nb+ Fe+ NI, an active metal that has chemical affinity with diamond.
+ Cu in the presence of either Hr or its alloy
-A This is done using a g-based brazing filler metal.
活性金属とダイヤモンドの接合は真空またはアルゴン等
の不活性富囲気を要するがN Cu−Ag系ろう材によ
る作業は空気中で行うことが出来る。Bonding of an active metal and diamond requires a vacuum or an atmosphere rich in inert gas such as argon, but work using an N Cu-Ag brazing filler metal can be performed in air.
また前記活性金属とCu−Ag系ろう材の間にはAuJ
ilffiを設け、酸化を防ぐことが好ましい。In addition, there is AuJ between the active metal and the Cu-Ag brazing filler metal.
It is preferable to provide ilffi to prevent oxidation.
Cu−Ag系ろう材に先立ち、所要金属のコーティング
を施しておいてもよい。A necessary metal coating may be applied prior to the Cu-Ag brazing filler metal.

イチップに合して製作した専用ホルダーに装着し、切削
試験を行った結果は下表の通りであった。The indexable insert shown in the drawing was attached to a special holder manufactured to fit the indexable insert, and a cutting test was conducted. The results are shown in the table below.
加工面粗さ記録から、送り量o、os、o、os鰭/r
eマの時の表面粗さの波形は規II+正しい。From the machined surface roughness record, feed amount o, os, o, os fin/r
The waveform of the surface roughness when using e-ma is Standard II+ correct.
これは、これらのバイトの切味の良さを示している。This shows how sharp these bites are.
