工具の製法に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for manufacturing carbide tools, and more particularly to a method for manufacturing milled carbide tools such as drills, end mills, reamers, and thread-cutting taps.
周知の通り、ドリル、エンドミル、リーマ等の工具は１
個々に使用目的に応じて異った刃を有するけれども、そ
れら全体に共通していることは。As is well known, tools such as drills, end mills, and reamers are
Although they each have different blades depending on their purpose, they all have one thing in common.

全長の一部分にダイヤモンド工具を用いて刃を加工し、
残った他部分をシャンクとするものであった。It has a cylindrical shank (cylindrical straight shank or tapered shank) on one side of its entire length, and a blade is formed on the other side. The negative side shank is the part where these tools are clamped to the holder or chuck of the machine, and for this reason, in addition to the finished surface roughness and specified hardness of this shank, the blade part It requires inseparability from the Therefore, the conventional manufacturing method for cutting tools such as drills, end mills, and reamers is to first process a rod-shaped body of ultra-hard material, cut it into the required unit length, and then use a diamond tool to cut a portion of the entire length. to process the blade,
The remaining part was to be used as the shank.

が製せられるけれども、刃付加工の為にダイヤモンド工
具を用いなければならない点や、刃付加工が高精度加工
、複雑加工である為に、その製造コストが高く、業界内
に於ける市場供給価格低減化の要望になかなか答えられ
ないのが実情であった。According to the above-mentioned conventional technology, since the shank part is integrally connected to the blade part, that is, it is formed of one piece, cutting tools such as drills, end mills, reamers, etc. can be manufactured with long lifespans. However, the manufacturing cost is high due to the need to use diamond tools for blade machining, and the high precision and complicated machining of blade machining, making it difficult to reduce the market supply price within the industry. The reality was that it was difficult to respond to requests.
そこで本発明の目的とする所は、従来のダイヤモンド工
具による刃付加工法を採ることなく、より安価に市場供
給できる粉末押出成型法による刃の形成方法を採用し、

重なるが故に強度的にも勝れた工具の製法を提供するに
ある。Therefore, the object of the present invention is to adopt a blade forming method using a powder extrusion molding method, which can be supplied to the market at a lower cost, without using the conventional cutting method using a diamond tool.
Our goal is to provide a manufacturing method that can process drills, end mills, and reamers at a lower cost overall.In particular, powder extrusion molding is a process that requires the blade shape to remain on the entire circumferential surface from one end to the other. As a result, there is no shank part at all, so instead of using a simple method such as simply connecting the shank to the rear end with brazing, it is better to use a blade-shaped part formed by powder extrusion. By removing a part to make it into a bar shape and forming a straight shank part there, the core of the shank part has a shank part that is integrated with the blade part, and it becomes one piece. Therefore, the objective is to provide a method for manufacturing a tool that is superior in terms of strength.
