MILLING MACHINING CENTER AND DRILLING MACHINING CENTER

摘要

PURPOSE: A milling center and a drilling center are provided to secure high automatization rate through automatic workpiece replacement, improve transmission of force, reduce the cost, and secure compact structure. CONSTITUTION: A milling center and a drilling center have a multi-spindle transfer type workpiece carrier(11) for receiving workpieces, a horizontal work spindle(7), and mechanical stands(1,2). A spindle housing(6) having the horizontal work spindle is disposed to an upper end fixed type stand component of the mechanical stands in a state transferable to a first horizontal shaft(9) by a motor. The workpiece carrier has an automatically operated workpiece-fixing device(19). The workpiece-fixing device is suspended to an upper end stand component in a state transferable between a second horizontal shaft(13) perpendicular to the first horizontal shaft and a vertical shaft(14). The workpiece-fixing device is movable between the work station of the work spindle and a workpiece-arranging device(24) disposed to the work spindle, for automatic workpiece replacement.
