The invention discloses a cross-shaped sliding table driving-type series-parallel spinal surgery robot, and belongs to the technical field of surgical robots. The invention aims to solve the problem that existing spine minimally invasive surgery robots cannot achieve active grinding and drilling functions. The spinal surgery robot comprises sliding bases, a four-degree-of-freedom parallel structure and an axial feeding structure, and the four-degree-of-freedom parallel structure is arranged between the two sliding bases in a connection mode; the four-degree-of-freedom parallel structure comprises an upper group and a lower group of cross-shaped sliding tables which are driven by synchronous belts, and the two cross-shaped sliding tables can achieve feeding in the X direction and the Y direction in a coordinate system XYZ; tail end movable platforms of longitudinal branches of the two sets of cross-shaped sliding tables are connected to the axial feeding structure, and the axial feedingstructure can be driven
