Laser application workshop, Korea am 15.01.2021
GFH-CEO Florian Lendner gave a lecture at the laser application workshop, korea on the topic: "Smart Ultrafast Laser Processing with Rotating Beam - Laser Micro Drilling, Cutting and Turning"
Smart ultra short pulse laser processing with rotating beam – laser micro drilling, cutting and turningSmart ultra short pulse laser processing with rotating beam – laser micro drilling, cutting and turning
Florian Lendner GFH GmbH, Germany
Current micro drilling, cutting and turning processes are mainly based on EDM, milling, stamping, honing or grinding. All these technologies are using a tool with a predefined geometry that is transferred to the working piece.
In contrast the laser is a highly flexible tool, which can adapt its size very fast by changing only a software setting. Thanks to the efforts in laser development during the last years, stable ultrafast lasers with sufficiant average power and high repetition rates became industrially available. For using as many pulses as possible, a cost-efficient production demands for innovative processes and machining setups with fast axes movement and special optics for beam manipulation.
GFH has developed a helical drilling optics, which rotates the beam up to 30.000 rpm in a very precise circle and allows furthermore to adjust the diameter and the incidence angle. This enables the laser to be used for high precision drilling and cutting and also for micro turning processes.
