Two spindle stocks (5,6) are provided on the frame (2) are relatively free to move in a Z axis direction and are located on respective sides of the chip collecting space. Workpiece spindles (5b,6b) are arranged in the spindle stocks and are free to rotate and are arranged mutually facing each other. Tool rests (7,9) are also provided which have respective turrets ( (7a,9a) which can assume various kinds of movement forms. Various kinds of machinings can be performed in such a way that the rotation control forms of the workpieces spindles and the spindle stocks are combined. A spindle drive motor controller is connected with the spindle driving motors of the 2 workpiece spindles.
