There is provided a machine tool capable of working a workpiece regardless whether it is gripped by a front spindle or a back spindle while guiding a free end side thereof by one guide bushing (160), is simplify and compacted and suppresses an increase of a number of axes to be controlled. The machine tool comprises the front and back spindles (112) and (122) having one and same axial line and disposed so as to face to each other and a guide bushing (160) having an axial line identical with the axial line. The guide bushing (160) is disposed between the front and back spindles (112) and (122), is configured so that the guide bushing (160) can guide the workpiece on both ends of the workpiece (W), so that the workpiece gripped either by the front spindle (112) or the back spindle (122) can be inserted, and so that the guide bushing (160) is movable in an axial direction. |
