Cutting of Free-form Parts with Low Coefficient of Thermal Expansion

Cutting and separating thin flat glass can be accomplished in several ways. Laser cutting using the filamentation technique results in high-quality cutting edges with an almost perfect perpendicular course to the surface and is characterized by high homogeneity and low roughness.

In the attempt to transfer the experience gained from separating standard materials with a high coefficient of thermal expansion (CTE) to glass with low CTE values, it became apparent that an adaptation of the laser cutting process was essential.

This whitepaper describes a laser cutting solution for Borosilicate and Alkali-free flat glass panels with low CTE from based on SCHOTT D 263 T.
