MRF™ polishing, exclusively available from QED, is flexible and fast, reliable and accurate. With an MRF machine on your shop floor, you can polish optical surfaces to pristine form, figure, and finish, regardless of symmetry, geometry, or slope variation.

1 天前 · However, MRF can polish surfaces with near-zero defects, ensuring absolute precision. 2. Damage-Free Polishing. One of the biggest challenges in polishing delicate materials—such as optical lenses, glass, and high-end semiconductors—is avoiding surface stress or micro-scratches. Since MRF polishing is a fluid-based process, it gently ...

Magnetorheological polishing (MRF) is a high-precision optical surface processing technology that uses a polishing fluid containing magnetic particles to form a flexible and fluid polishing tool under the action of a magnetic field to achieve material removal and complete the precision polishing and correction of the optical surface.

QED Technologies International is the pioneer and exclusive provider of MRF® (Magnetorheological Finishing) and SSI (Subaperture Stitching Interferometry) systems for the precision optics industry. Polish Smarter. Polish Better. MRF brings more capability and flexibility to precision optics polishing. Measure Smarter. Measure Better.

The 50 mm MRF wheel can polish small surface features and reduce edge effects. The 370 mm MRF wheel has high material removal rates to cover large surfaces quickly. The Pad Polisher allows for pre-polishing or smoothing:

MRF Magneto-Rheological Finishing. It is the way to polish a workpiece by means of the shear force generated by delivering the MR (magnetorheological) fluid containing abrasives into a rotating wheel, and plunging the workpiece into the abrasibes, which is suitable for final polishing or polishing correction of precision optics.

After considering the correction process by ions (ION-FinishTM), this blog post will focus on magnetorheological finishing (MRF). This correction method is a mechanical polishing process for optical surfaces. Targeted, local material removal corrects the optical surface and enables lowest surface roughness values (Rq < 0.3 nm).

2001年6月30日 · At the heart of MRF is a magnetorheological polishing fluid that is used to preferentially polish based on dwell time, with a typical removal function area of 1 cm 2. The process methodology characterizes the surface errors in the workpiece and deconvolves the removal function with an empirically determined error function to create dwell time ...

Learn how MRF (magnetorheological finishing) systems increase reliability and determinism in the production process, enabling consistent quality, shorter lead times, and on-time delivery of optics products.

2020年6月17日 · MR polishing fluid (MRPF) is a clever, viscosity-changing, controllable material under the application of a magnetic field. MRPF is composed of magnetic particles,...
