Laser Cutting of Glass

Complete Separation in One Workstep

Flat glass scribe and break processes are traditionally used to mechanically separate glass. This process very often does not allow to avoid micro cracks and chipping along the scribe line, significantly influencing the bending strength of glass substrates.

Using suitable lasers for glass scribing and cutting, sharp edges and crystal clear walls can be achieved. Lab tests with customer samples have to be realized for the suitable laser choice and process parameters.

Traditionally CO2 lasers of different power classes as well as ultashort pulse lasers can be used.

Laser cutting of glass – benefits for the user:

  • Laser Glass scribing and cutting can significantly reduce the required process steps, which are necessary to separate glass mechanically
  • Material bending strength as well as thermal shock resistance is enhanced by factor 2 – 3 for a better product quality
  • Cutting of tube glass for clean cutting without creating any particles
