COMPLEX MACHINING MACHINE TOOL AND A MACHINING METHOD FOR THE USE OF THE MACHINE TOOL

摘要

A complex machining machine tool having a single frame in which a chip collecting space is provided at the center portion, a first and a second spindle stocks on the frame being relatively free to move and drive in Z axis direction in the shape of holding the chip collecting space, workpiece spindles on said spindle stocks being free to rotate and drive in the shape of facing mutually, and tool rests. The tool rests and the turrets can assume various kinds of movement forms. Furthermore, the complicated and various kinds of machinings can be performed in such a manner that the rotation control forms of the workpiece spindles and the spindle stocks are combined.
