A large-aperture MRF machine, the Q22-750P2 extends MRF figuring capability to large, long radius parts.


The Q22-750P2 includes the latest MRF technology:
    • QED.NET software
    • EFMS fluid control system

Technical capabilities include:
    • Polishing plano optics up to 1000 mm x 750 mm
    • Polishing of long radius sphere, asphere and freeform
    • Multi-part polishing software

Dual-wheel platform provides high flexibility:
    • The 370 mm wheel has high material removal rates to
      cover large surfaces quickly.
    • The 50 mm wheel can polish small surface features
      and reduce edge effects.

  Multiple Applications

• Large segmented telescope optics
• Large, light-weighted optics with very thin face sheet
• Improved surface integrity, e.g., for resistance to laser damage
• Phase plate corrections

MRF Advantage

  • Works by magnetically manipulating the properties of the MR polishing fluid and adjusting the workpiece position and polishing dwell time via computer control.
  • Conforms to complex surfaces, providing the flexibility to polish aspheric and freeform shapes.
  • Significantly reduces cycle times due to its high rate of removal.
  • Maintains process stability with constant recirculation of the MR fluid (no dulling of the polishing tool).
  • Provides a completely deterministic process that can be characterized to very high precision.
  • Provides an affordable, turnkey system for precision optics manufacturing that will broaden your design options and enhance your cost effectiveness.
