For use in the aerospace industry, Bielomatik has developed the Mobile Lubrication Unit (MLU) in close cooperation with an aircraft manufacturer. According to the company, the solution can be directly connected to all commercially available Advanced Drilling Units (ADU). A special challenge was apparently presented by the typical sandwich materials titanium, CFRP and aluminum used in aircraft construction. However, if the device is adapted to the relevant ADU and the process is perfectly set and tested, the CFRP should reportedly remain dry. The unique selling point is seen in the special control system through which the MLU automatically switches the MQL process on and off and thus adapts to the relevant material requirements. As the developers explain, at the beginning of each shift, the worker fills the removable one-liter cartridge tank at a fuelling station with its fluid supply, which is monitored by a control system in the MLU during the shift. Alternatively, an empty tank can be exchanged for a full tank. After initial tests with prototypes together with a tool manufacturer, the feedback is said to have been very promising, and not only in the aerospace industry.
Minimum quantity lubrication for advanced drilling units
At the suggestion of the aviation industry, Bielomatik has developed a portable device for eco-friendly minimum quantity lubrication. It is specially designed for direct use on advanced drilling units.
