The gantry machining center is suitable for processing large parts. The base is designed with honeycomb staggered stiffeners. The width of the base of the whole gantry machine tool is consistent with the width of the workbench, making its structure more stable. The connection part between the column and the base of the gantry adopts a 45 ° slant span, which not only increases the connection strength between the base and the column, but also increases the rigidity of the machine tool in strong cutting. Gantry machining refers to the machining center set vertically between the spindle and the workbench. Therefore, it is used for the processing of large parts.

The horizontal machining center is suitable for machining box type parts. The horizontal machining column is a moving column structure, which slides back and forth, and the workbench slides left and right. This structure has the advantages of high precision, strong rigidity and long service life. It can greatly improve the production efficiency, but it has high cost and large land occupation. Horizontal machining center refers to the machining center with the spindle axis parallel to the workbench, which is especially suitable for boring and high-precision boring. It is also suitable for the strong machining of the end face and the curved surface machining of the die.
