The invention provides a non-shaft high-precision static pressure numerical control rotary worktable. The rotary worktable adopts a hollow non-shaft structure; the surface of the worktable and a motor rotor are directly arranged on a bearing rotor of a liquid static pressure bearing respectively; and the rotary worktable adopts a realizing mode of direct-drive motor driving, rotary encoder feedback and computer numerical control, so that the rotary worktable lowers the difficulty of processing, assembling and adjusting parts of the rotary worktable, improves the precision of the rotary worktable and has the characteristics of compact structure, small inertia and high dynamic property and rigidity. The designed positioning precision of the rotary worktable is 3.5 angular seconds, the repeated positioning precision of the rotary worktable is 1 angular second, the resolution is 0.5 angular second, the radial rigidity is 4,000N/mu m, and the axial rigidity is 30,000N/mu m.
