Why does make MRF® Make a difference?

At the heart of every MRF Polishing System is a magnetically-sensitive (magnetorheological) “smart fluid” which changes viscosity in milliseconds when exposed to a magnetic field.  This is important because it creates a small polishing tool. The MR fluid temporarily stiffens and conforms to the surface of the component being finished. This allows geometries of almost any shape to be polished as easily as a spherical optic.

What also makes MR fluid unique is that the fluid is very stable and does not show wear like a traditional polishing tool. Think of sandpaper that doesn’t load up or become dull. You know that the first surface will be produced as easily, and accurately, as the last.

The MR fluid is characterized before a polishing cycle. In other words, we measure how fast it will remove material on a given type of optic, based on material and geometry. This removal function doesn’t change.  It allows manufacturers to very accurately predict what the final output will be, even before the manufacturing run.

A computer numerical controlled, precision workstation and sophisticated computer algorithms help ensure that the MRF Polishing System is automated and robust. An easy-to-use touchscreen interface guides the operator through every step of the automated process. Stability, predictability and repeatability reign throughout.
