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.

Complex machining machine tool

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.
