This machining center system has a significant influence on a country's aviation, aerospace, military, scientific research, precision machinery, high-precision medical equipment and other industries. There are many types of overall layout structures of the existing five-axis linkage machining center, the most common ones are vertical-horizontal conversion five-axis compound machining center and cradle-type five-axis compound machining center.

In the utility model, by providing a screw, a screw barrel, a rotating rod and a level bubble, the efficiency of installation and leveling of the five-axis machining center can be effectively improved.

When the blower is used for heat dissipation, due to the relatively closed interior of the five-axis machining center, turbulence will occur, the wind pressure is large, the ventilation volume is small, and the heat dissipation efficiency is low.
