Transformative advancement in fine finishing has been achieved with the development of magnetorheological abrasive flow (MRAF) technology.This innovation represents a significant leap beyond conventional abrasive flow machining by introducing real-time,precise control over the machining process,enabling unparalleled accuracy for ultra-precision components.The core innovation lies in a smart abrasive medium—a mixture of magnetic particles,abrasives,and a carrier fluid.When subjected to a controlled magnetic field,the medium instantly changes its rheological properties,increasing in viscosity and yield strength in direct proportion to the field's intensity.
This unique characteristic allows operators to dynamically "program" the medium's stiffness and abrasive force during the machining cycle without stopping the process.By using strategically placed electromagnetic tooling,the system can locally intensify polishing action precisely where needed on a complex part,such as sharp edges or specific contours,while leaving delicate features untouched.This level of spatial and temporal control makes MRAF ideal for finishing critical components in optics,aerospace,and biomedical industries.
It can achieve nanometer-level surface finishes on intricate geometries,such as fuel injector nozzles or medical implant surfaces,with exceptional consistency and without subsurface damage.By enabling selective,controllable,and ultra-precise material removal,magnetorheological abrasive flow technology is redefining the limits of what is possible in precision manufacturing.Abrasive Flow Machine Uses Diamond Fine Powder,Silicon Carbide Powder or other Abrasives Mixed Into Polymer Elastic as a soft medium.The abrasives flow up and down through the inner holesor over the machined surface to achieve surface polishing.Especially suitable for all kinds of mould and irregular shape tiny cavities.

Abrasive flow is not only a device,but also a system engineering!It includes equipment,abrasives,tooling fixtures,and important detail design and experience,which are not only reflected in the final effect and efficiency,but also reflected in the long-term stable use,and can help customers save a lot of trial and error costs!The one-way automatic circulating fluid polishing machine uses the lower hydraulic cylinder to move and squeeze,so thatThe soft abrasive is extruded from the same inlet and from other channels,and repeatedly ground toTo achieve the purpose of polishing,deburring and chamfering.This processing method is applicable to all kinds of curved flow channels,elbows or slender pipes,and large internalCavity and other workpieces that are not easy to polish,or precision parts to remove cross hole burrs,is the most importantSuitable processing method.
And the grinding direction is consistent,which can effectively improvePerformance,quality and service life of the die or workpiece.After polishing,the finish can reach the mirror grade,and the best surface roughness can reach ra0.2μm.The two-way reciprocating circulating fluid polishing machine makes the soft abrasive flow through the inner hole,machining surface or end angle by means of the motion extrusion of the upper and lower oil pressure cylinder blocks,and moves up and down for fine grinding,so as to achieve the processing of polishing,deburring and chamfering;
This processing method is the most suitable processing method for complex shapes that are not easy to polish,such as various special-shaped holes,tooth surfaces,concave convex surfaces,or for removing cross hole burrs from precision parts.And the grinding direction is consistent,which can effectively improve the performance,quality and service life of the mold or workpiece.After polishing,the finish can reach the mirror grade,and the best surface roughness can reach ra0.025~ra0.01 um.
