The invention provides a stereoscopic engraving machine and belongs to the technical field of machines. The stereoscopic engraving machine solves the problem how to improve the processing efficiency of an existing stereoscopic engraving machine. The stereoscopic engraving machine comprises a base and a gantry beam connected to the base and capable of moving horizontally in the longitudinal direction; a supporting table is arranged on the portion, below the gantry beam, of the base; the gantry beam is provided with a long-strip-shaped tool frame provided with a plurality of tool heads; a horizontal moving structure is arranged between the tool frame and the gantry beam and the tool frame is made to form three-dimensional stereoscopic horizontal movement relative to the supporting table; thetool frame can swing with the strip-shaped direction of the tool frame as the axis; a long-strip-shaped workbench is arranged on the supporting table; the workbench and the tool frame are arranged inparallel and the workbench can swing with the strip-shaped direction of the workbench as the axis; and the upper side of the workbench is provided with a plurality of positioning mechanisms used forpositioning workpieces. The stereoscopic engraving machine forms a double-swinging structure, and the processing efficiency is improved.
