The invention relates to a motion working table, in particular to a platform capable of realizing multi-axis motion. The planar type three-axis motion platform comprises a base, a working table, an unpowered shaft, an A-axis motion unit, a B-axis motion unit and a C-axis motion unit; the unpowered shaft, the A-axis motion unit, the B-axis motion unit and the C-axis motion unit are fixedly connected onto the base; and the workbench is fixedly connected to the unpowered shaft, the A-axis motion unit, the B-axis motion unit and the C-axis motion unit. The planar type three-axis motion platform is used for translational motion and rotation within a planar range, wherein translational motion comprises two degrees of freedom, and rotation comprises one degree of freedom. According to the planar type three-axis motion platform, three motion units and one unpowered shaft are supported on four end points of the working table, so that the working table is good in stress state and is high in structural rigidity; and a linear guide rail is used as a guide mechanism, so that friction resistance is small, transmission efficiency is high and motion precision is high.
