Laser cutting of glass

Laser cutting of glass stands out by a high cutting speed and high cut quality.

Glass tubes and flat glass can be separated by laser radiation. There are two laser processes available: stress-induced cutting and sublimation cutting.

Stress-induced cutting is suitable for flat glass and glass tubes with thicknesses > 0.5 mm. It stands out by extremely high cutting speeds and high cut qualities. During this process, a laser heats the glass either as a whole or just on the surface and the material expands locally. During the cooling phase, the material breaks at the pre-defined places where the laser beam had heated the glass.

Sublimation cutting, however, is especially well-suited for cutting thinner glasses, or for cutting contours with a radius. Here, the glass is locally vaporized with continuous wave and pulsed laser systems. Cutting glass with this method is very flexible.
