A machine tool has first and second spindles provided so as to face each other. The first and the second spindles are synchronously rotated without stopping their rotation. A machined workpiece, after a first machining routine, in a state of rotation is directly delivered from the first spindle to the second spindle, and a second routine of machining is immediately performed.
