They are usually used to process heavy workpieces such as molds, aerospace components, ship structures, etc. Their design features enable them to have higher processing accuracy and stability, and can meet complex and high-demand processing tasks. Gantry machine tools usually consist of a crossbeam and two columns. The crossbeam spans across the top of the two columns to form a "gate" structure. This design can effectively improve the rigidity and stability of the machine tool and reduce vibration and deformation that may occur during the processing. The crossbeam is usually equipped with a spindle, which can perform various cutting, milling, drilling and other processing operations.

Then, the external power supply starts the first driving motor 28, and drives the pulley 30 to rotate through the first threaded rod 29, and the first threaded rod 29 is used to rotate the pulley 30. The belt 31 drives the first threaded rod 29 in the moving rail 24 on the other side to rotate, so that the bottom ends of both sides of the door frame 26 slide synchronously on the outer surface of the first threaded rod 29, and the guide rod 27 limits the moving direction of the moving seat 25, so that the main shaft 36 is in the required position. Secondly, the external power supply starts the second driving motor 32, and drives the second sliding block 34 to move through the second threaded rod 33, so that the second guide rail 35 is in a suitable position, and then the second guide rail 35 is started to drive the main shaft 36 to move up and down to process the workpiece to be processed.
