To provide a turning center capable of improving both of working precision of a work by a machining tool and working precision of the work by a rotating tool.

A machining tool dedicated clamp device 3 and a rotating tool dedicated clamp device 5 independently arranged in parallel with each other against a spindle stock device 1 are mounted on a table 2. A machining tool clamp shaft 3B integrating a machining tool T1 in the axial direction and in the rotating direction by clamping it is fixed impossible to rotate against a casing 3A on the machining tool dedicated clamp device 3. A rotating tool clamp shaft integrating a rotating tool T2 in the axial direction and in the rotating direction by clamping it is supported free to rotationally drive through a bearing device against a casing 5A on the rotating tool dedicated clamp device 5.
