Laser processing

During selective laser ablation, the thinnest layers of the ceramic are removed to create three-dimensional depressions, for example. The high-precision energy input of the laser enables the finest structures to be produced.

Separation processes can also be realised with lasers. Laser drilling produces the smallest fine and precision bores from 40 μm diameter, for example for cooling ducts or for venting.

For the production of functional surfaces, microstructuring can be used to roughen components in a targeted manner in order to improve the adhesion of lubricating films or tribological properties. This is typically applied to shafts of air bearings and plain bearings.

Laser processing can also be used to permanently apply lettering and markings to the ceramics. For example, the insertion of part numbers and markings enables the traceability of the component.
