Compared to a standard CNC machine, the deep hole drilling machine offers a number of significant advantages when drilling holes with special drilling depth. Machining time and a tool change are saved on holes when the pilot drill is eliminated from the drilling process. Depending on the design of the deep drilling machine, it is also possible to drill several components simultaneously. By using professional deep drilling machines, an exceptionally good drilling quality can be achieved, even to a maximum drilling depth of several meters. The deep drilling machines are specially designed for deep drilling and therefore equipped with high pressure pumps and filters. The result when deep drilling holes with special drilling depths is extremely reliable operation throughout the deep drilling process.
