Abstract
A headstock assembly for a machine tool includes a mount having a female threaded bore, a headstock mounted slidably relative to the machine base, a drive member mounted on the headstock, a spindle, and a spindle extension. The spindle has an intermediate segment disposed in a chamber of the headstock and coupled to be driven by the drive member so as to permit the spindle to rotate about a spindle axis. The spindle extension is coupled to be rotatable with the spindle, and has a male threaded segment configured to be in threaded engagement with the female threaded bore so as to permit the headstock to be linearly moved relative to the mount.
