Highlights

  • Multi purpose, 4-axis CNC machine that can be used for generating contours on prisms, generating cylinder optics and aspheres (AspheroTool Software Package required)
  • Tool spindle with KombiTool Technology (KombiTool / KombiTool+ [link]) for high precision surface processing (Pre- and fine grinding in one tool without changing the tools); Edging and chamfering possible
  • Precise plano surfacing to polishable quality due to optimised grinding parameters with multi-cut technology, adjusted speed and feed rates for all spindles
  • Angular accuracy of the C-Axis ± 10"
  • Gantry with hydraulic clamping system for prisms 
  • Two-stage machining in one operation using combination tool technology (KombiTool Technology)
  • Highly dynamic AC servo drives for all axes
  • Minimal set-up times thanks to dialog menu-guided operation
  • Tool clamping via direct flanging or with optional hydro-expansion clamping technology (Ø 40 x 60 mm DIN)
  • Directly flanged tools at KombiTool Technology
  • Optimization of the grinding process through multi-stage cuts with adapted feed rates and speeds of all spindles

Options

  • High resolution C-Axis Encoder available
  • Generating cylinder optics and aspheres (AspheroTool Software Package required)
  • Other tool connection interface on request
