場合は主軸は固定し、ワークを回転させる加工を行うよ
うになっている。Machine tools that perform processing with rotating tools and turning tools have a spindle for mounting each tool.When machining with a rotating tool, the spindle is rotated, and when machining with a turning tool, the spindle is fixed. It is designed to rotate the work.
また旋削工具を主軸に取付けて旋削加工を行う場合、主

端面で支持するようになっている（例えば特公昭５９−
３３５６５号）。Also, when turning with a turning tool attached to the main spindle, a large-diameter taper part that receives a load is provided at the end of the main spindle, and the taper part of the turning tool abuts this large-diameter taper part, which occurs during machining. The cutting resistance to be supported is supported by the large-diameter tapered portion and the end face of the spindle (for example, Japanese Patent Publication No. 59-
33565).

に結合されていたことにより、結合部の剛性に問題があ
った。However, in the above-mentioned conventional turning with a turning tool, if the large-diameter tapered portion and the spindle end surface receive cutting resistance, a shim is inserted between the spindle end surface and the turning tool in order to bring the large-diameter tapered portion and the spindle end surface into close contact at the same time. It is necessary to adjust the axial direction in the axial direction, which requires a lot of time for this adjustment, resulting in poor work efficiency.Because this adjustment must be performed every time a tool is added, tool compatibility is improved. There was a problem such as lowering it. Further, since the large-diameter taper portion is connected to the main shaft side, there is a problem in the rigidity of the connecting portion.

る。The present invention has been made in view of the above, and when turning with a turning tool, it is not necessary to adjust the turning tool and the spindle, and since there is no need to adjust with this spindle, the turning tool is compatible. In addition, since the turning tool is coupled to the head main body side at two locations in the radial direction, the large-diameter taper portion and the small-diameter taper portion at the base of the turning tool,
An object of the present invention is to provide a head device for a machine tool, which is capable of greatly increasing the rigidity of this joint.
