<p>A numerically controlled machine tool (11) for machining a large work, comprising a spindle support side structural body (13) which moves a spindle (75) to which a tool is attached in X-, Y-, and Z-directions, a work support side structural body (15) having an indexing work mounting table (99), a chips delivery means (17) which is positioned between the spindle support side structural body (13) and the work support side structural body (15) and delivers chips produced in the machining area to the outside of the machining area, whereby the work (89) setup operation can be performed with the work mounting surface of the work mounting table (99) facing upward because the work mounting table (99) is allowed to be indexed and the setup operation can be shortened and machine operation rate can be increased, and also the machine tool can be manufactured and installed easily because the spindle support side structural body (13), work support side structural body (15), and chips delivery means (17) can be configured separately from each other.</p> |
