DLC 820 – Display Laser Cutting

The DLC 820 is a universal, multi-axis laser cutting machine that modifies unstrengthened or chemically strengthened transparent glass substrates by ultrashort pulse lasers with high cutting speed, accuracy and high-quality cutting edges (~ 90 ° edge, no heat-affected zone, highest breaking strength, < 30 μm chippings, edge roughness ~ 0.4 μm). Laser marking or scribing are also possible.

FEATURES

The PCL controlled three-axis machine DLC 820 disposes of two laser sources and processes glass substrates of up to 1,300 mm x 1,100 mm.

  • Stand-alone system or line integration
  • Up to 2x scanner heads
  • Up to 2 fixed optical process heads
  • Linear or free forms
  • Manual, semi-automatic or fully automatic handling possible
  • MES interface
  • Integrated process metrology
  • Vision system available
  • Import of CAD files (e.g. DXF, DWG) possible

You can find further information in the download box on the right.

ADVANTAGES

  • Cost savings through high-quality cutting edges (no downstream processes such as grinding necessary)
  • Higher breaking strength of the glass compared to conventional cutting, as edge roughness is very low, no heat-affected zone (HAZ) and almost no chipping and micro cracks
  • High throughput through highly dynamic process of up to 2.5 m/s (depending on glass material and thickness of the glass)
  • Fast format change possible for small batches
