PROBLEM TO BE SOLVED: To provide a lathe capable of machining a long workpiece while preventing vibrations and supporting it, and delivering the workpiece between opposed working spindles. SOLUTION: This lathe includes two working spindles, which are opposed to each other on the same axial line and whose relative movement is controlled; two turret tool posts either above or below the working spindle axial line; and a third tool post having a tool shaft either below or above the axial line. The two turrets have a vibration-prevention tool, and can synchronously move toward at least one working spindle and the working spindle axial line. The third tool post has a workpiece supporting tool controlled by a B-shaft, and the movement of the third tool post is controlled in the working spindle axial line direction and an orthogonal direction.
