PROBLEM TO BE SOLVED: To simplify a double-spindle lathe to provide a compact structure, and also improve a chip spattering prevention device for the chips produced in a working space.SOLUTION: This machine tool includes a machine frame including: two workpiece spindles 8, 8'; a cutting tool holder 12 with a plurality of cutting tools 13; a transfer device 18 for a plurality of workpieces 10; and a chip scattering prevention device 20 with two inclined plates 25, 25'. The cutting tool holder 12 is disposed movably along the machine frame. The plurality of workpieces 10 can be cut alternately by the plurality of cutting tools 13 in the two workpiece spindles 8, 8'. Therefore, the workpieces 10 are exchangeable in one of the workpiece spindles 8, 8' on a case-by-case basis. Each of the two workpiece spindles 8, 8' can be moved to load positions 19, 19' from working positions 17, 17' where the workpieces 10 are allowed to be cut. Since the workpiece spindles 8, 8' are loaded and unloaded, the inclined plates 25, 25' can be moved from the areas between the working positions 17, 17' and the load positions 19, 19', to standby positions 26, 26'.
