CNC Optical Polishing Machine Mrf for Precision Surface Error Correction and Nanometer

It supports deterministic correction of flat, spherical, aspheric and freeform surfaces. The feasible aperture, radius, sag, local normal angle and workpiece mass must be evaluated from the drawing, fixture and collision envelope.

B/C mechanical rotary axes work with the software virtual A axis to orient complex surfaces. The reachable angle is not a single universal value; it depends on optic geometry, wheel diameter, fixture and tool-path strategy. A 3D feasibility review is recommended.

Quick loading, multi-station handling, guided setup and automated calibration improve repeatability and reduce auxiliary time. Actual cycle time still depends on incoming error, required removal, substrate, wheel size, process route and metrology loop.

Magnetorheological Finishing (MRF) is a deterministic optical polishing technology that uses magnetorheological fluid to achieve precise and controlled material removal. It is widely used for high-precision polishing of aspherical, freeform, spherical, flat and steep optical surfaces.

Our MRF polishing machines can process various optical materials, including fused silica, optical glass, BK7, quartz, silicon and other hard optical materials. The suitable polishing parameters can be customized according to the material and surface requirements.
