Abstract: A complex machine tool has a single frame having a chip collecting space at a center portion thereof, first and second spindle stocks on the frame, relatively free to move and drive in a Z axis direction and holding the chip collecting space therebetween, workpiece spindles on the spindle stocks free to rotate and drive and facing each other, and tool rests. The tool rests have turrets and can assume various kinds of movement. Complicated and varied types of machining can be performed combining the rotation control of the workpiece spindles and the spindle stocks.

Abstract: 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.

Abstract: A composite machining lathe having a tool holder base movable in the direction of the axis of the spindle and a tool magazine. The tool magazine has a continuous elongated flexible tool carrier adapted to run along a path having a curved section. A plurality of tools are carried by the tool carrier in such a manner that the tools on the portion of the tool carrier in the curved section of the path are selectively engageable with a head bore formed in the tool holder base. The tool magazine is mounted such as to be movable together with the tool holder base in synchronism in the direction of axis of the spindle and in the direction perpendicular to the axis of the spindle. The tool holder base is mounted in such a manner that it is movable to and from a retracted position relatively to the tool magazine. Tool holding means are provided on the tool holder base for holding the tools on the tool carrier.
