Advanced Laser Micro Machining Using a Novel Trepanning System

The LMTB has designed and implemented a novel optical concept for the development of a versatile trepanning system, enabling the adjustment of the displacement and the inclination angle during circular rotation at up to 20000 r.p.m. The presented trepanning systems are able to laser machine through-holes diameters of 100 m with a negative taper of up to 5. Starting from an early stage of implementation, the novel trepanning system has been customized for different applications and industrial partners. The conference paper outlines the development steps and advanced performance, accenting laser micro machining results utilizing the novel LMTB trepanning system in operation at different laser parameters.
