みに起因したクイルの偏位によつて加工精度が低
下するという問題があつた。 Generally, a quill feed type power unit used in machine tools consists of a main shaft to which a tool is fixed at the tip, a quill that surrounds this main shaft and supports the main shaft so that it can rotate freely in the circumferential direction, and a quill that supports the main shaft so that it can freely slide in the axial direction. and a drive source that rotationally drives the main shaft, and when working with the tool, the main shaft is rotationally driven by the drive source, and
The main shaft is moved together with the quill to the limit of movement in the distal direction. In the conventional quill feed type power unit of this kind, the shaft head body supported the quill with a slight gap in the radial direction, which caused the problem that the blade vibrated during machining. Therefore, a quill feed type power unit has also been proposed in which an axial slit is formed in the shaft head body and the shaft head body is tightened when the quill moves to the limit of movement in the distal direction, thereby eliminating the radial clearance. However, this power unit has the problem that the mechanism for tightening the shaft head body is complicated and expensive, and that machining accuracy is reduced due to deviation of the quill due to distortion of the shaft head body during tightening.
