A dragon-gate processing machine having a dragon-gate support structure, at least one lateral girder coupled to the support structure for mounting tool holding members and automatic tool exchange devices, a plurality of working tables mounted below the dragon-gate support structure, driving apparatus for driving the working tables, a mechanical transmission for coupling the drive apparatus to the working tables, an auxiliary rotary arm mounted to the dragon-gate support structure for holding auxiliary processing devices, and control means for controlling operation of the dragon-gate machine. The dragon-gate machine allows processing such as drilling, latching, and planing to be performed on a workpiece mounted on the working table. The novel invention allows such processing to be performed at any angle and at any desired direction according to the processing requirements of the workpiece.
