The structure of a vertical machining center refers to a machining center where the spindle and worktable are set in a vertical state. The vertical machining center integrates the characteristics and functions of various CNC machine tools. Vertical machining centers are developed from basic CNC milling machines, and also integrate the characteristics and functions of CNC milling machines. Their structures are basically the same, and their machining processes are somewhat similar. The difference between vertical machining centers and CNC milling machines is that machining centers have automatic tool changing devices and tool libraries, while CNC milling machines do not have this function. A vertical machining center can complete multi process machining such as milling, boring, drilling, tapping, and threading by clamping the workpiece in one go. Moreover, a vertical machining center can achieve at least three-axis two linkage, while a general vertical machining center can achieve three-axis three linkage. Some can perform five axis and six axis control, and the more control axes, the wider the machining range.

Do you still remember that we just analyzed the advantages of CNC vertical machining centers in the previous text? There are mainly three types, namely CNC vertical machining centers, which have a simple and easy to understand structure, convenient clamping, are conducive to cooling, have a wide range of applications, and are easy to remove chips. They can effectively avoid damage to the surface of the workpiece, have a small footprint, and vary in price. Do you know about the determination of CNC vertical machining centers? The main disadvantages of CNC vertical machining centers are as follows:

1. Due to the parallel relationship between the spindle and worktable of a vertical machining center, there is a certain height limit for the processed workpiece. In addition, there are also size limitations for fixtures and tools, and the robotic arm takes up a lot of space when changing tools.

2. From the above drawbacks, it can be seen that the possibility of CNC vertical machining centers processing box type workpieces is relatively small because their range of processing box type workpieces is relatively small. This is one of the biggest drawbacks of vertical machining centers.
