Vertical turning, milling and grinding combined high-precision machine tool

The invention discloses a vertical turning, milling and grinding combined high-precision machine tool which comprises a machine body placed in a plant, and a workbench is installed at the front end of the machine body; the first sliding seat and the second sliding seat are arranged on the outer sides of the left displacement threaded rod and the right displacement threaded rod in a threaded sleeving mode correspondingly. The fixed column is fixedly mounted in the middle of the upper end of the workbench so as to place a workpiece; and the driving motor is mounted in the lower end of the workbench in an embedded manner. According to the vertical turning, milling and grinding combined high-precision machine tool, through the movable rods arranged in the limiting grooves in an attached mode, when a driving motor is started, a driving disc and the like are used for driving the movable rods to position and clamp workpieces, chippings in the limiting grooves where the movable rods are located are blown and removed,
