In one aspect, a swiss-type machine tool is provided that includes a workpiece holding shaft, a workpiece supporting shaft, and a tool holder associated with the workpiece supporting shaft for holding at least one tool. The machine tool includes a drive operable to rotate the workpiece holding shaft and the workpiece supporting shaft around an axis. The workpiece holding shaft has a work holder configured to secure a workpiece to the workpiece holding shaft. The workpiece holding shaft is axially shiftable relative to the workpiece supporting shaft to adjust a position of the workpiece relative to the workpiece supporting shaft. The machine tool further includes a removable workpiece support, such as a guide bushing, configured to be releasably connected to the workpiece supporting shaft and rotate therewith. The workpiece support slidably contacts the workpiece and permits axial movement of the workpiece relative to the workpiece support.
