The invention discloses a multifunctional numerical control machining center, and aims at providing the multifunctional numerical control machining center, wherein the multifunctional numerical control machining center has the beneficial effects that clamping of the next batch of components can be conducted while components are machined, the clamping time is shortened, and the integral machining efficiency is improved. According to the technical scheme, the multifunctional numerical control machining center is characterized in that the interior of a machining cavity is in sliding connection with an isolation door, and the isolation door divides the machining cavity into an inner cavity and an outer cavity; a tool clamp base is located in the inner cavity, a machining table comprises a pre-arranging table located in the outer cavity and a workbench located in the inner cavity, and the pre-arranging table and the workbench are connected through a steering mechanism rotationally connectedto the middle position of the base; the steering mechanism comprises a middle rotation shaft rotationally connected to the base, the pre-arranging table and the workbench are both fixed to the middlerotation shaft, and the base is further provided with a steering piece for driving the middle rotation shaft to rotate by 180 degrees; and when the components are machined, detachment of the previousbatch of components and pre-clamping of the next batch of components can be conducted, accordingly, the time needed for clamping is shortened, and the integral machining efficiency of the componentsis improved.
