Laser polishing of glass surfaces and edges
Laserverrundete Glaskante

With laser-based melting, edges can be rounded off and surfaces can be polished locally. This process is non-tactile, can be used for different geometries, and does not require polishing agents.

Laser polishing is used to smooth the glass surface, and thus to achieve a higher surface quality of the glass.

Mechanically processed glass plates or glass components have a higher risk of breakage. Laser polishing significantly improves the mechanical strength of the glass components and removes micro cracks. The processing method increases the brilliancy of the glass, making it, among other things, interesting for the lighting industry.

If the surface of the components should only be polished in certain areas, the laser polishing process can be limited to those. This process is very flexible and thus even suitable for different complex workpiece geometries.
