In the automobile, locomotive, shipbuilding, aerospace, construction machinery industries; especially for super-long laminated plates, longitudinal beams, structural steel, tubular parts and other porous systems, drilling and processing of various large-scale parts that are rich in source and sea should be the first choice. CNC drilling machine is a digitally controlled hole processing machine tool mainly for drilling. Due to the development of machining centers, most CNC drilling machines have been replaced by machining centers. However, some parts with drilling as the main processing process still need to be processed by CNC drilling machines, such as processing printed circuit boards, so there is still a certain demand for CNC drilling machines. Most CNC drilling machines use point control and move along two or three axes simultaneously to reduce positioning time. In addition, on the basis of the three-coordinate CNC vertical drilling machine, a turret-type tool magazine and an automatic tool-changing mechanism can be added to form a drilling machining center (drilling center). The drilling center can not only perform drilling, expanding, reaming, countersinking, tapping and other hole processing procedures, but also can complete contour-controlled milling with linear and circular interpolation. Drilling centers are mainly used for the processing of small and medium-sized parts in the electrical and mechanical industries.
