旋盤作業を自動化する上で大きな問題であった。Conventionally, in the lathe work, one worker is attached to one lathe, but in order to improve the work efficiency, the lathe work is automated or the work by the worker is performed. Reduction is needed. For this purpose, it is necessary to have a technology of supplying the material to be cut to the lathe and discharging the material after cutting from the lathe, and a bite capable of obtaining a stable cutting surface that does not require manpower for a long time. Especially, it is difficult to automate the attachment and detachment of the vibration-proof material to and from the cylindrical material to be cut. However, the conventional method of cutting a cylindrical work piece using a vibration isolator is not sufficiently suitable for automation,
It was a big problem in automating the lathe work.

それほど大きなものではない。The present invention will be described in detail below. Generally, a lathe has a headstock for imparting rotation to the material to be cut and a tailstock for supporting the other end of the material to be opposed to this, and further a reciprocating motion for attaching a bite and giving feed. There is a table (turret) on it. Working conditions such as the angle of each part of the cutting tool, cutting speed, and feed when using a turning tool to cut the material to be cut include the chip generation mechanism, cutting resistance, cutting temperature, tool life, cutting surface roughness, It affects chatter vibration. The chatter vibration generated during cutting includes forced chatter vibration and self-excited chatter vibration.
Possible causes of the chattering vibration are unbalance of the rotor and vibration due to the structure of the lathe. However, the rigidity of the lathe is increasing, and the chattering vibration is not so large except in special cases.

As one of the preventive measures against this, it is effective to adopt an appropriate vibration-proof material.
The anti-vibration material used in the present invention has shape retention,

The elastic tubular body is detached from the inner surface of the tubular cutting material.

As described above (collectively in such a situation, the present invention simply refers to fitting), it is necessary to maintain a constant shape, and the thickness of the tubular portion is usually 0.5 mm to 10 mm, preferably. It is about 1 mm to 8 mm. Also, the thickness of the closed portion at one end is approximately the same as the thickness of the tubular portion.

By rotating about the axis, most of the tubular portion of the bottomed elastic tubular body is in close contact with the inner surface of the tubular work material. The closed portion at one end of the hollow elastic tubular body may have a flat plate shape, or may have a bulge or a convex portion on the outside or inside of the hollow elastic tubular body.

A hollow cylindrical body having a shape-retaining property and made of an elastic body, one end of which is closed and the other end of which is open, and the outer surface of the cylindrical portion of the cylindrical body is the cylindrical cut object. By using a hollow elastic tubular body that is configured to fit on the inner surface of the material, chatter vibration that occurs during cutting can be prevented, and it is easy to automatically attach and detach the vibration isolator to the tubular work material. In addition, the lathe work can be automated by using the commonly used conveying means for the cylindrical material to be cut.
