Vertical drilling machines belong to a large category of machine tools, characterized by their upright form. After prolonged use, CNC vertical drilling machines may encounter some problems. How can we avoid thermal deformation during work? This involves the design issue of CNC vertical drilling machines. In order to reduce the thermal deformation problem of CNC vertical drilling machines, some measures should be taken during the design process. The heat generated inside the machine tool is the primary heat source for thermal deformation, and the heat source should be removed from the host as much as possible. Nowadays, most CNC vertical drilling machines have external motors, gearboxes, and hydraulic equipment. As for heat sources that cannot be separated from the host, such as spindle bearings, they can reduce the internal heating of CNC milling machines.

The spindle component is a critical component that directly affects machining accuracy, and the bearing on the spindle of a CNC vertical drilling machine is a large internal heat source. In addition to using fine rolling bearings and smoothing the bearings with oil mist on the CNC vertical drilling machine, static pressure bearings can also be used, which are beneficial for reducing the temperature rise of the CNC vertical drilling machine spindle. In the spindle box of the precision CNC vertical drilling machine, efforts should be made to prevent the use of conflict clutches and other heating elements.
