Deep hole drilling counts among the special disciplines within the field of machining, particularly as these kinds of machining steps usually require special equipment in terms of both tools and machines. As a machine manufacturer, WFL equips the machine in such a way that it has a number of decisive advantages over a classic deep-hole drilling machine. Almost all industries that utilise complete machining have workpieces that require deep-hole drilling. Ultimately, it is the tasks performed in the respective industry that give rise to differences in the process. In the aerospace industry, it is necessary to machine materials such as titanium, Inconel and other heat[1]resistant alloys. Deep hole drilling is challenging with these materials because the tools are subject to heavy wear and controlled chip breakage requires special measures. As a machine manufacturer, WFL requires comprehensive expertise when it comes to using the right tools and selecting the optimum cooling lubricant. Deep holes in the plastics industry must exhibit extremely high cylindrical dimensional accuracy. Some of these workpieces are subsequently honed to ensure the required quality can be achieved. When performing deep hole drilling in the crankshaft industry, on the other hand, accessibility is vitally important because the oil holes are manufactured in a wide variety of angular positions. The decisive factor here is a flexible machine concept, which facilitates reaching a wide range of angles without setup work for drilling the corresponding holes. Perfect accessibility is possible here thanks to the swivelling B-axis of the Millturn machines.
