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 flexible tool, which can adapt its size very fast by changing only a software setting.
GFH has developed a helical drilling optics, which rotates the beam up to 30.000 rpm in a very precise circle and allows to adjust the diameter and the incidence angle. The laser can be used for high precision drilling, cutting and micro turning processes.
