Deep drilling methods enable the production of boreholes with a particularly large drilling depth compared to the diameter and are used economically from a length-to-diameter ratio of approx. L/D = 10. The three classic deep drilling methods in industrial use are single-lip deep drilling, ejector deep drilling and BTA (Boring and Trepanning Association) deep drilling. BTA deep drilling is used in a diameter range of about d = 10...1500 mm in the different drilling variants of solid, core and top drilling. BTA deep hole drilling is often used at the end of the value chain for machining expensive components such as hydraulic cylinders, transmission shafts and aircraft landing legs. Here, the component already has a high equivalent value, making high process reliability and compliance with tight manufacturing tolerances of enormous technical and economic importance.

The aim of the research project is the development and research of a mechatronic tool system, for the compensation of the center course. By means of a process-parallel detection and analysis of the center run, continuous tool-side compensations are introduced. Overall, the new tool system enables the productive production of high-quality bores with the BTA deep hole drilling process.
