The gantry milling machine and the gantry machining center and the gantry milling machine are all classified as large-scale CNC machine tools. The processing objects of the two are basically the same, and they are suitable for processing large workpieces, such as large casting sheet metal parts or large box parts, and are widely used in the mold processing industry. The machining process of the gantry milling machine and the gantry machining center is basically the same, and the bed structure is also similar (gantry milling machine

        Both the gantry machining center and the gantry milling machine are automated machining CNC machine tools controlled by the CNC system program. The machining accuracy and processing efficiency of both are attributed to the high-performance CNC machine tools. The more intuitive difference between the two is that the gantry machining center has a tool magazine with an active tool changer, while the gantry milling machine does not have a tool magazine. It is not difficult to see that the gantry machining center equipped with a tool magazine has the function of active tool change, so it can be said that the machining accuracy of the gantry machining center is higher than that of the gantry milling machine.
