The video shows laser processing of the CFRP-face of a wristwatch in the high-price segment. Through optimized process strategies and beam sources, the influence of heat can be reduced to such an extent that even with high-resolution microscopes, no heat-affected zone in the cross section can be seen (left image). This means that even the narrowest contours can be created, which burn with a conventional laser cutting process and break out during milling. This kind of laser processing offers new opportunities and degrees of freedom for the production of CFRP components.

During his doctoral thesis, the owner of PMLT spent several years developing processes for laser processing of fiber-reinforced plastics. Due to the high thermal conductivity of the carbon fibers at a high sublimation temperature and the low damage and sublimation temperature of the surrounding plastic, laser processing of CFRP is particularly challenging. PMLT offers cutting edge technology in this area.

The following video shows the cycle time-optimized laser processing of 10 rivet holes with a diameter of 5 mm in CFRP with a wall thickness of 2.5 mm in real time (10 holes in one second!).
