MRF™ Polishing

Q-Flex 100

Q-flex systems bring more capability and efficiency to any optics shop, from volume production to prototype shops.

Q-flex systems offer all of the legendary determinism of MRF finishing, plus increased flexibility and repeatability in modular, production–ready platforms that help you manufacture smarter. Q-flex systems deliver unprecedented manufacturing capabilities—especially for difficult spheres aspheres, and freeforms.

Flexible Technology

  • Modular MRF head design for fast tool-free changeovers.
  • Fluid Control Module (FCM) provides improved fluid stability, calibrated and repeatable performance, plus quick fluid changes and easy cleaning.
  • QED.NET software with easy-to-use wizards, is fully configurable for optimum throughput with any level of operator skill.

Flexible Architecture

The Q-flex systems’ heads and FCMs are common across family platforms, and can be shared between Q-flex machines. In minutes, MRF heads can be changed from 10 mm, 20 mm, 50 mm and 150 mm size to accommodate your polishing needs.

Engineered for Excellence

The modularity of Q-flex systems means you can match the machine to your workload, bringing greater efficiency to your precision optics shop. Q-flex systems are designed for a production-oriented environment.

Q-flex systems offer all of the legendary determinism of MRF finishing, plus increased flexibility and repeatability in modular, production-ready platforms that help you manufacture smarter. Q-flex systems deliver unprecedented manufacturing capabilities—especially for difficult spheres aspheres, and freeforms.

In minutes, MRF heads can be changed from 10 mm, 20 mm, 50 mm and 150 mm size to accommodate your polishing needs.

  • Heads can be selected to optimize polishing tool size (spot), concave part radius, freeform geometry and more.
  • Heads are quickly and kinemetically adjusted  for rotational, raster or freeform modes.
  • Head realignment is automated with a built-in probing station.
  • Head carts are provided for efficient operation and convenient parts storage.
  • Faster and easier setup after cleaning, with greater day-to-day and operator-to-operator repeatability

The Fluid Control Module (FCM) houses the fluid delivery system hardware and controls in one package.

  • With multiple FCMs, fluid changeovers can be completed in minutes.
  • MRF fluid can be maintained in bypass within or remotely from the base machine.
  • Cleanup is easy: the FCM is on wheels and can be moved to a cleaning station.
  • With new EFMS (Electronic Fluid Monitoring System) fluid control system, you get improved fluid strength control.

Typical Capabilities

Form/figure correction

High convergence
5-10x improvement in 1 iteration
Irregularity
As low as λ/30-λ/40 (PV) or lower, limited by metrology reproducibility

Roughness improvement

Micro-roughness
< 1 nm rms on most materials with any MR fluid / < 0.5 nm rms on most glasses and single crystals with specific MR fluids
Ultra-low micro-roughness
0.1-0.2 nm rms achievable on some materials with specific MR fluids

The results listed above are typical values.

Surface quality/integrity improvement

  • Increase laser damage resistance
  • Remove subsurface damage
  • Remove stress
  • Remove haze, fine cosmetics on sensitive glasses

Induce specific form/figure for special purposes

  • Correct transmitted wavefront error by polishing only 1 surface
  • Correct prism angle error
  • Correct thickness variation of thin film
  • Create “phase plate” or induce other specific aberrated surface error

Specifications are subject to change without notice.

* Please note that workpiece geometry and weight specifications are approximate values to be used as general guidelines. Due to other factors such as workpiece inertia that are difficult to quantify, there are parts outside this range that can indeed be run under certain circumstances, as well as parts within this range that may not run under all circumstances. Please use caution when attempting parts outside these limits, or contact QED for further guidance.

** Radius range dependent on specific part geometry and heads geometry
