【発明が解決しようとする課題】しかしながら、かかる
従来のワーク内周面の切削加工においては切削加工中に
バイトシャンクとワークとの間にびびり振動が発生し、
このびびり振動が加工精度の劣化や工具寿命の短縮など
を招くとの問題があった。However, in the conventional cutting work on the inner peripheral surface of the work, chatter vibration is generated between the bite shank and the work during the cutting work.
There is a problem that this chatter vibration causes deterioration of machining accuracy and shortening of tool life.

トシャンクが長くなると前記びびり振動がより生じ易く
なる。Particularly, in such a cutting process, it is necessary to make the protruding length of the bite shank longer than the working depth of the work. Therefore, as the working depth of the work becomes deeper, the protruding length of the bite shank becomes longer. As the bite shank becomes longer, the chatter vibration is more likely to occur.

じ易くなる。Further, when the inner diameter of the work is small, it is necessary to make the tool shank small and thin to match it, but when the tool shank becomes thin in this way, the rigidity of the tool shank decreases and similarly chatter vibration occurs. Is likely to occur.

果は著しく低下してしまう。Here, the mounting means for mounting the ultrasonic vibration cutting tool on the tool rest of the lathe is made of a vibration-proof alloy as described above. Generally, vibration-damping alloys have a high damping ability against vibrations generated in the vibration-damping alloys by an external force, and a damping effect can be expected, but when the amount of strain generated by an external force (cutting force) increases, The damping effect will be significantly reduced.
