Water-jet Cutting

With this option inner and outer cuts can be produced in a short cycle time with high precision. The edge quality can be increased and the cutouts can be lined, due to an additional milling and seaming spindle.

Advantages 

  • variable cutting contours, no restrictions by tools
  • compared with conventional milling: Process Factor 2.0
  • automatic glass disposal of standard cutouts
  • suitable for the processing of laminated glass
  • water curtain for the protection of surrounding machine components
  • controlled capture of the abrasive sand
  • radiant energy is absorbed
  • specific water flow in separate tanks
  • high edge quality
  • seaming spindle for seaming / finishing

Technical data

  • Max. glass size: 3300 x 20000 mm
  • Min. glass size: 250 x 450 mm
  • Max. working speed: 15m/min
