ELC 420 – Electronics Laser Cutting

The ELC 420 is a multi-axis laser machine with 4 process heads for high-throughput applications. It cuts and ablates material (preferably sapphire, glass or ceramics) by a short-pulse laser. The machine is designed in particular for highly precise processing.

FEATURES

The PLC controlled one-axis machine ELC 420 cuts discs (e.g. lenses) with a diameter of approximately 5.5 mm out of sapphire glass with several available laser sources. The wafers are either round (2 inch diameter) or square (up to 55 mm x 55 mm) and approximately 0.4 mm thick.

  • Stand-alone system or line integration
  • 2 process heads
  • Several laser sources available
  • Fully automatic handling (mass production) or semi-automatic handling (R&D) possible
  • MES interface
  • Integrated process metrology
  • Vision system available
  • Import of CAD files (e.g. DXF, DWG) possible
  • Fully integrated, high effective exhaust system

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
  • Fast format change possible for small batches
