Description

Technical Field

[0002] The column of a vertical machining center is an important part used to assemble the necessary components of the vertical machining center, such as the spindle box, tool magazine, electrical box and motor. Therefore, the column must bear the total weight of the components such as the spindle box, tool magazine, electrical box and motor as well as its own weight, which will cause the load to be concentrated on the two side walls of the column, resulting in poor rigidity of the column and inability to withstand heavier loads; and in the process of cutting the workpiece, when the spindle box moves up and down, it causes vibration of the entire equipment and unstable changes in the axial force, which leads to uneven movement and may cause the rigidity of the column itself to deteriorate.
