Combined processing machine

A combined processing machine comprising:

• a first workpiece main spindle device and a second workpiece main spindle device including each including a main spindle stand configured to rotatably hold a main spindle about an axis;
• a first turret device and a second turret device including a turret configured to attach multiple turret tools disposed respectively above the first workpiece main spindle device and the second workpiece main spindle device;
• a tool main spindle device disposed between the first turret device and the second turret device, the tool main spindle device including a main spindle head configured to exchangeably and rotatably hold a main spindle head tool;
• and
• two separation shutters configured to partition between the first turret device and the second turret device, on both sides of the tool main spindle device in a width direction,
• wherein the two separation shutters form a first processing chamber of the first workpiece main spindle device and the first turret device, a second processing chamber of the second workpiece main spindle device and the second turret device, and a tool exchange chamber of the tool main spindle device in the combined processing machine.
