Abstract: A compact, multiple spindle computer-controlled machine tool is disclosed. The machine may have a spindle base with two spindles disposed vertically relative to one another along an axis, the spindles having parallel axes of rotation. The spindle base may be computer controlled and have z and x axis motion relative to a tool post. The tool post may have a tool turret and may provide computer-controlled y axis motion so that the tool turret may be utilized with both spindles. The tool post may also have a machining unit that may be used to machine workpieces held by either spindle.
