Abstract
A bar work loading apparatus for loading a bar work into a head traveling type vertical machine tool. The machine tool has a headstock rotatably supporting an approximately vertical main spindle and movable in the direction of the axis of the main spindle and a direction perpendicularly intersecting the axis of the main spindle. A chuck is provided at the lower end of the main spindle. The machine tool further has a controller for controlling the movement of the headstock and the rotation of the main spindle and also controlling the opening and closing operation of the chuck. The bar work loading apparatus is provided near the machine tool in side-by-side relation and has a holding member capable of holding at least one bar work in such a manner that the axial direction of the bar work is parallel to the axial direction of the main spindle at least at a work receiving position where the chuck receives the bar work, which is in a range within which the center axis of the main spindle is movable.
