【発明の詳細な説明】
［産業上の利用分野１
本発明は、超音波モータ、圧電ブザー等で用いるＰＺＴ
材料の穴明は加工に関するものである。[Detailed Description of the Invention] [Industrial Application Field 1] The present invention relates to PZT used in ultrasonic motors, piezoelectric buzzers, etc.
Drilling of materials is related to processing.
［発明の概要］
本発明は、穴明は加工せしめんとする円柱状ＰＺＴ材事

止するものである。[Summary of the Invention] In the present invention, an acrylic plate is bonded using an adhesive to the drill advancing direction side of a cylindrical PZT material 4 to be drilled. A through hole is drilled with a carbide drill to prevent damage to the PZT material.
〔従来の技術１
従来、円柱状ＰＺＴ材料に貫通穴を明けるには、該材料
をコレットチャックにて保持し、原材料のまま貫通穴を
超硬ドリルにて明けていた。[Prior art 1] Conventionally, in order to drill a through hole in a cylindrical PZT material, the material was held with a collet chuck, and the through hole was drilled with a carbide drill while the raw material was in use.
［発明が解決しようとする課題］
しかしながら、従来の方法では、ドリル進行方向側に大
きな欠損が生じてしまい、材料歩留り低下の大きな要因
となっていた。[Problems to be Solved by the Invention] However, in the conventional method, a large defect occurs in the drill advancing direction, which is a major factor in reducing the material yield.
また、これらの欠損の発生を防止するには、材料を所定
量加工した後、超硬ドリルを取りはずし、刃先の研摩を
行なう必要があり、加工時間が長くなるという欠点を有
していた。Furthermore, in order to prevent the occurrence of these defects, it is necessary to remove the carbide drill and polish the cutting edge after processing a predetermined amount of material, which has the disadvantage of prolonging the processing time.
〔課題を解決するための手段Ｊ
以上の問題点を解決するために、本発明では、穴が貫通

着した。[Means for Solving the Problems J] In order to solve the above-mentioned problems, in the present invention, just before the hole penetrates, an acrylic layer is placed on the side in the direction in which the drill advances so that the PZT material does not break due to the thrust force applied to the material. I glued a disc made of
〔作用］
従来法で、ドリル進行方向側にＰＺＴ材料の割れが発生
するのは、貫通穴が明く寸前にＰＺＴ材料が軸方向つま
りスラスト方向に力を受け、この力により材料割れが発
生することにある。[Function] In the conventional method, cracks occur in the PZT material in the drill advancing direction because the PZT material receives a force in the axial direction, that is, the thrust direction, just before the through hole is opened, and this force causes the material to crack. There is a particular thing.
従って１貫通穴が明く寸前にＰＺＴ材料が受けるスラス

するプレートにアクリル樹脂を選定したのは、切削性が
良好でありかつ安価であるためである。Therefore, it is possible to prevent the above-mentioned cracking by bonding an acrylic plate to the end face of the drill in the advancing direction for reinforcement so that it can withstand the thrust force that the PZT material receives just before the first through hole is opened. Here, acrylic resin was selected for the plate to be bonded because it has good machinability and is inexpensive.
〔実施例１ 次に、本考案の実施例を示し、さらに詳しく説明する。[Example 1 Next, embodiments of the present invention will be shown and explained in more detail.

When 0 pieces were machined and the probability of occurrence of cracks in the direction of drill advance, that is, defects, was calculated, the method according to the present invention had a probability of occurrence of defects of 0%, whereas the conventional method had a probability of occurrence of defects of 20%.
Therefore, it has become clear that the method according to the present invention is an invention that greatly improves the drawbacks of the conventional method.
