Deep hole drilling is a metal cutting method for producing primary cylindrical deep bores with a length-to-diameter ratio larger than l/D = 10. Due to the increasing interest of different branches of the industry in inner contoured workpieces, the Institute of Machining Technology (ISF) and the BGTB GmbH developed a chamber boring system, which allows to contour boreholes in axial and radial directions. This paper presents the influence of different cutting speeds, feeds and workpiece materials on the contour accuracy and the mechanical tool loading.
