である。(Prior art and its problems) Conventionally, in order to drill a nozzle hole in a disk nozzle made of vitreous high-density carbon, a carbide tip coated with diamond, nitride, etc. 1 was used as shown in Figure 2. A high-density carbon disc 3 is cut using a cutting drill 2 made of (tungsten carbide).
The nozzle hole 4 is drilled straight through the nozzle hole 4, but the high-density carbon disc 3 is hard and brittle, and machining distortion occurs in the nozzle hole 4.
As a result, as shown in FIG.
When the nozzle hole is drilled with a cutting drill consisting of II,
Since the cutting drill wears out and becomes unable to cut, it ends up pushing through the nozzle hole, making the entrance of the nozzle hole prone to cracking.

穿孔方法を提供することを目的とするものである。(Objective of the Invention) The present invention has been made to solve the above-mentioned problems, and is a disc nozzle made of high-density carbon that does not cause the opening periphery of the nozzle hole to crack and become missing, or the entrance of the nozzle hole to crack. The purpose of this invention is to provide a method for drilling holes.
（問題点を解決するための手段）
上記問題点を解決するための本発明の高密度カーボン製
円板ノズルの穿孔方法は、高密度カーボン製円板ノズル

底を貫通することを特徴とするものである。(Means for Solving the Problems) The method for drilling a high-density carbon disc nozzle according to the present invention to solve the above-mentioned problems includes: , use a drill to drill a nozzle hole with a bottom leaving at least about 115 mm of the thickness of the disk, then turn the disk over and use a drill to penetrate the bottom of the nozzle hole. This is a characteristic feature.
本発明の穿孔方法に於いて、円板の厚さの少なくとも１
ノ５程度の厚さを残して有底のノズル孔を穿設する理由
は、これ以上深くノズル孔を穿設すると、加工歪がノズ
ル孔の開口部に集中して割れるようになるからである。In the drilling method of the present invention, at least 1 of the thickness of the disk
The reason why a bottomed nozzle hole is drilled leaving a thickness of about 5 is because if the nozzle hole is drilled deeper than this, processing strain will concentrate on the opening of the nozzle hole and cause it to crack. .
その後反転してノズル孔の底をドリルにて貫通した際そ
の奥端がわれてもノズル孔の内周壁には何ら影響を及ぼ
すことが無い。Thereafter, when the drill is turned over and the bottom of the nozzle hole is penetrated with a drill, even if the rear end is bent, there is no effect on the inner circumferential wall of the nozzle hole.
（実施例）

孔４を形成した。First, an example will be described. As shown in FIG. 1a, a high-density carbon disk 3 with a diameter of 100mm and a thickness of 51mm is cut using carbide (tungsten carbide) coated with nitride 1 at the tip. 11 of the thickness of the disk 3 at Druri 2
A bottomed nozzle hole 4 is drilled leaving a thickness of 5, that is, 1 m, and then, as shown in FIG. A nozzle hole 4 was formed by penetrating the bottom 4b.
