The invention relates to the technical field of numerical control machine tools, in particular to a turning and milling composite rotary table for a machining center. A rotary table bearing is installed between the outer side of a rotating shaft of the working table and the inner side of the upper portion of the base. A friction plate is installed on the portion, located on the lower side of the rotary table bearing, of the base. A brake pad is installed below the friction plate. The brake pad is fixed on the boss; and an oil cylinder is arranged below the brake pad in the base. According to the technical scheme, during milling, the friction plate and the brake pad interact through the oil cylinder, then the mandrel drives the workpiece to stop rotating, during turning, the piston rod of the oil cylinder is far away from the brake pad, the friction plate and the brake pad are separated, the mandrel can drive the workpiece to rotate, and the workpiece is turned. Through the structure, free conversion of the tu
