Bielomatik: minimal quantity lubrication for advanced drilling units

Especially developed for aircraft construction: Following a suggestion by the aerospace industry, bielomatik has developed a mobile device for the environmentally compatible minimal quantity lubrication. It is particularly intended for use with automatic advanced drilling units.

For the use in the aerospace industry, bielomatik Leuze GmbH + Co. KG from Neuffen, Germany, developed the “Mobile Lubrication Unit (MLU)” in close cooperation with an aircraft manufacturer. It can be directly connected to all commercially available “Advanced Drilling Units” (ADU). A special challenge was presented by the typical sandwich materials titanium, CFRP and aluminium which are currently used in aircraft construction. “If the device is adapted to the relevant ADU and the process is perfectly set and tested, the CFRP should remain dry,” explains Marcel Schlierer, designer at bielomatik. The unique selling point is the special control system using which the MLU automatically switches the MQL process on and off and in this way individually adapts to the relevant material requirements.


At the beginning of each shift, the worker fills the removable 1 l 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 was very promising not only in the aerospace industry. Schlierer: “bielomatik has already received requests – for example by band saw manufacturers – for simple applications with external MQL. The start of series production of the mobile device, which is intended for retrofitting, is planned for the fourth quarter of 2016.

A clean job: With the support of an aircraft manufacturer, a “Mobile Lubrication Unit (MLU)” for the minimum quantity lubrication during drilling using “Advanced Drilling Units (ADU)” was developed.
