The invention relates to the technical field of turning, and specially discloses a turning device with an integrated carriage. A vertical carriage mechanism and a transverse carriage mechanism are arranged on a main spindle box in an integrated manner, the structure layout of a conventional turning machine tool is thoroughly subverted, a work bench of the conventional turning machine tool is removed, and therefore the turning device is more compact in structure and smaller in occupied area, and can be carried and installed more conveniently, a work bench which can block an operator from a chuck does not exist, and therefore feeding and blanking can be carried out from the front side of the chuck, and the operation is more convenient; by employing the structure without the work bench, fragments, liquid coolant and the like can be collected and cleared more conveniently.
