長さより十分に長い中クリバイト３が緬付ポルト２４１
によシ螺着締付けられ石。Conventionally, as a means of this kind, as shown in a side view of the main part with a part cut away in FIG. 1
Firmly grip the tool, and hold a medium-sized clibaite 3 that is sufficiently longer than the longitudinal length of the workpiece on the tool rest.
The stone is tightened with screws.
そしてチャック台が駆動源によシ回転され、刃物台が左
右に摺動して、被加工物１の内径が中ぐりバイトによシ
切削加工される。Then, the chuck stand is rotated by the drive source, the tool rest slides left and right, and the inner diameter of the workpiece 1 is cut by the boring tool.
しかし、このような通常の旋盤作業での中ぐりバイト３

わり、中ぐりバイト３が弾性変形をおこし、不均等量の
撓みが発生する。However, the boring part 3 in normal lathe work like this
When mounting the tool to the tool rest U, the tool is mounted using a so-called cantilever support, and the force due to cutting resistance is applied to the tip of the boring tool 3, causing elastic deformation of the boring tool 3, resulting in an uneven amount of deflection. .
この結果、例えば長さ２２αｍａ内径３５ｍ、ｍ、鋼鉄

な工数がかかつている。As a result, when precision machining the elongated inner diameter of a steel high-speed motor component with a length of 22αma and an inner diameter of 35m, for example, the accuracy of cylindricity is poor at about μm. I was forced to do this, and it took a huge amount of man-hours, 3 hours/piece, to create this workpiece 1.
ここにおいて本発明は、従来手段の難点を克服し、切削
部材に撓みが生起しない加工精度の高い円筒体の中ぐり
切削方法を提供することを、その目的とする。SUMMARY OF THE INVENTION An object of the present invention is to provide a method for boring a cylindrical body with high machining accuracy, which overcomes the drawbacks of conventional means and does not cause deflection of the cutting member.

。In the present invention, a boring bar equipped with a tip for cutting a workpiece is supported on both sides, and the tip of the boring bar is fitted and loosely fitted into the inner ring of a bearing installed on the inner peripheral surface of a chuck stand. This is a method for boring a cylindrical body by sliding the chip in the axial direction during machining.
