), a plate-shaped chip (B+) (82) was separately brazed and then the blade was processed. Generally, brazing welding is a manual process, and there are technical problems in manufacturing the blades of cutting tools, which especially require uniformity. Therefore, due to deformation due to heat and other reasons before the product is made, even if the blades are made with a blade f dimension, the contact surface between the two chips will not be optimal, resulting in a large number of defective products. This caused an increase in manufacturing costs.

の低減は次表の通り素晴らしいものである。C1. Effects of the Invention The method for manufacturing the blade portion of a cutting tool according to the present invention has an important feature in that the step of cutting the plate-shaped tip is a pre-step to the cutting process. That is, the manufacturing method of the blade part according to the present invention simplifies the process of brazing welding work, and the plate-shaped chip cut into two pieces can be brazed and welded at the optimal position as the blade part. . Furthermore, the occurrence of defective products due to deformation due to heating etc. during the manufacturing process has been drastically reduced. In particular, the accuracy of cutting tool blades, which require uniformity, improved during the rainy season. Therefore, improvement in product reliability and manufacturing cost due to improvement in product accuracy
The reduction is remarkable as shown in the table below.
即ち、チップ取り付け部の加工とチップ取り付けに要し
たコストが、本発明の製法では従来製法の約１／３近い
コストで済むようになった。又、１日当たり生産量は、
新製法では旧製法の約２８倍の高能率である。以上のご
とく生産コストの大幅な削減となった。That is, the manufacturing method of the present invention reduces the cost required for processing the chip attachment portion and attaching the chip to about 1/3 of that of the conventional manufacturing method. Also, the production amount per day is
The new manufacturing method is approximately 28 times more efficient than the old manufacturing method. As described above, production costs were significantly reduced.
従来工法と本発明の工法の対比
（板状チップを使用した場合）
又不良品発生率の減少は、次表の通りである。不良品発
生率も新製法では従来製法の約１５．４％に激減しな。Comparison of the conventional construction method and the construction method of the present invention (when plate-shaped chips are used) The reduction in the incidence of defective products is shown in the following table. With the new manufacturing method, the rate of defective products has also been drastically reduced to approximately 15.4% of the conventional manufacturing method.
以上のごとく、新製法による工程数の半減と不良品数量
の激減による切断工具の製造コスト削減のメリッｌ〜は
、多大なものがある。As described above, the new manufacturing method has many advantages in reducing the manufacturing cost of cutting tools by halving the number of steps and drastically reducing the number of defective products.
今一つの重要な効果は、従来製法による２片のチップの
ろう付けを、新製法による１片のチップのろう付け後に
チップを切断する工程に変更したことにより、２片のチ
ップの間が、切断工具の刃にとって常に最適な接触面を
持つこととなった。従って、切断工具として最適の製品
精度を常に維持できるようになったことである。Another important effect is that by changing the process of brazing two pieces of chips using the conventional manufacturing method to the process of cutting the chip after brazing one piece of chip using the new manufacturing method, the gap between the two pieces of chips has been cut. This ensures that the tool blade always has an optimal contact surface. Therefore, it is now possible to always maintain optimum product accuracy as a cutting tool.
