The invention discloses a constant flow static pressure working table for a gear shaping machine or a gear milling machine. By constant flow static pressure technology, a static pressure cavity is formed on a central spindle, and lubricating oil is fed into the static pressure cavity by a constant pressure oil pump, so that an oil film is formed between the spindle of the working table and a pedestal to keep contact surfaces between the spindle and the pedestal in a constant pressure full-liquid lubricating state; therefore, the center of the working table is positioned well, a wear phenomenon is almost avoided during movement, and the rigidity and the accuracy of the working table are greatly improved and the life of the working table is greatly prolonged; and the pedestal is provided with a dual lead worm, and adjusting pads are arranged in both axial direction and radial direction of the worm, so the working table can work under a smaller backlash condition, and the dividing accuracy of a rotary working table can be improved.
