Numerical control plasma cutting machine

The invention relates to the technical field of cutting machines, in particular to a numerical control plasma cutting machine. Comprising a machine tool body; bottom plates are evenly and vertically arranged on the inner side of the machine tool body. A moving assembly; the moving assembly is located at the upper end of the machine tool body. An output shaft of the moving assembly extends to the position above the bottom plate. A cutting head; the cutting head is connected to an output shaft of the moving assembly and used for completing plasma cutting. The cutting head is driven by the moving assembly to move in the three-dimensional direction. A controller; a pressing ring; the center of the pressing ring is located under the cutting head. The pressing ring is located on the outer side of the cutting head. According to the plasma cutting device, the periphery of the cutting position of the to-be-cut plate is pressed through the pressing ring, so that the to-be-cut plate can be cut in a flat state, the situa
