Custom Manufacturing Capacity 7 :  Magnetorheological Polishing(MRF)
Magnetorheological fluid used in magnetorheological polishing is a kind of intelligent material, which is composed of magnetic particles, base fluid and stabilizer. Under the action of magnetic field, it can realize the reversible conversion of solid-liquid two-phase in 1ms. Magnetorheological effect refers to the phenomenon that magnetorheological fluid is a liquid that can flow without magnetic field, and its rheological properties change sharply under the action of strong magnetic field, which is similar to the properties of solid, and then recover its flow characteristics when the magnetic field is removed. Magnetorheological (MR) polishing technology is a kind of flexible "small grinding head" with viscoplastic behavior, which is formed by the rheology of Mr polishing fluid in gradient magnetic field. It has a rapid relative motion between the grinding head and the workpiece, so that the workpiece surface is subject to a great shear force, and the material on the workpiece surface is removed. Magnetorheological polishing (MRF) is a comprehensive technology which is applied to optical surface processing, such as electromagnetic theory, hydrodynamics, analytical chemistry and so on.
Magnetorheological (MR) polishing machine is used for high-quality and efficient processing of large-diameter optical parts. By combining with the matching process, it can realize the precision polishing and surface shape correction of various shapes and sizes of optical parts within the processing range, achieve the required processing accuracy and surface quality, and improve the processing efficiency.

M ain Cutting Technologies Advantages:
1).No stress;
2).Subsurface damage;
3).High polishing accuracy;
4).The surface roughness is small;
5).Flexible shear has excellent cloud removal characteristics;
6).Bingham fluid is formed by traditional free abrasive polishing under the action of magnetic field, which can realize flexible polishing;
7).Machining and polishing the complicated surface shape, the optical elements are processed determinedly; By controlling various process parameters, it is easy to control the size, shape and strength of the flexible "small grinding head", so as to control the material removal rate. By controlling the motion trajectory and dwell time, various geometric surfaces can be machined (suitable for spherical surface, aspheric surface, free-form surface, etc.)
8).Widely used in optical glass materials such as fused silica, zerodur, soft materials such as Si, CaF2, ZnSe, hard materials such as RB SiC, s-sic, KDP crystal processing, metal mirrors, etc;
9).The polishing spot correction and compensation algorithm can determinedly remove the low frequency error of optical elements and effectively suppress the medium and high frequency error at the same time;
