うにするためＫは、二つの主軸を設けなければならなか
った。Turning using a machine tool involves turning the workpiece without rotating the tool itself to shape the workpiece, and milling involves rotating the tool itself without turning the workpiece. Therefore, in order to perform both turning and burring with one machine tool, K had to provide two main spindles.
しかし、一台の工作機械に二種の主軸を設けることは機
械自体を大型化し、かつ構造自体も複雑化し、したがっ
て価格も高価にならざるを得ない。However, providing two types of spindles in one machine tool increases the size of the machine itself, complicates its structure, and therefore increases the price.
本発明は、従来の工作機械におけるこのような不具合全
解消すべく案出したものであって、−個の主軸しか有し

ので加工物をミーリング加工できる。Since the tool mounting device for a machine tool according to the present invention has the above-described configuration, during turning processing, after the turning tool is mounted on the spindle, the turning tool is fixed to the spindle head by the holding means and the suppressing means is When the main spindle is fully compressed and tightened, it is possible to overcome the force generated during turning, which causes the tool to rotate, move left and right, and move up and down. In addition, when milling, after pressing the turning tool and releasing it from engagement with the spindle head, attach the milling tool to the spindle and perform milling, the turning tool will rotate as the spindle rotates. Can mill things.
以下、本発明の実施例について説明する。Examples of the present invention will be described below.
