Combined working machine

A combined working machine comprising:

• a bed in which a front inclined surface which is inclined forward in a front-rear direction of the working machine is formed;
• a first workpiece main spindle device and a second workpiece main spindle device disposed on the front inclined surface of the bed to be opposite to each other, each of the first and second workpiece main spindle devices including a main spindle stand configured to rotatably hold a main spindle about an axis, each main spindle stand being mounted on a main spindle slide such that the first and second workpiece main spindle devices are movable in an axial direction of the main spindle perpendicular to the front-rear direction of the working machine;
• a first turret device and a second turret device, each of the first and second turret devices including a turret configured to attach multiple turret tools respectively disposed above the main spindle of the first and second workpiece main spindle devices on the bed in an up-down direction of the working machine perpendicular to both the front-rear direction of the working machine and the axial direction of the main spindle, and respectively disposed behind the first and second workpiece main spindle devices in the front-rear direction of the working machine:
• and a tool main spindle device disposed between the first turret device and the second turret device on the bed and including a main spindle head configured to exchangeably and rotatably hold a main spindle head tool.
