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.The manufacturing of aero-engine blades,particularly for their intricate internal cooling channels,represents one of the most demanding applications for abrasive flow machining (AFM).Significant breakthrough has been achieved by moving from a uniform,bulk-flow process to a targeted,digitally-controlled finishing operation.The core of this advancement lies in intelligent media delivery and real-time monitoring.
Traditional AFM could struggle with the complex,varying geometries of serpentine cooling channels,often leading to inconsistent material removal or even blockage.
The breakthrough involves using adaptive,multi-viscosity media systems whose flow properties can be dynamically adjusted during the cycle.This is paired with sophisticated fixture tooling embedded with sensors that monitor pressure and flow in real-time.This data is fed into a machine learning algorithm that adjusts extrusion parameters on-the-fly,ensuring every section of the channel,from the inlet to the tightest bend,receives a consistent and precise polishing action.
This targeted approach guarantees the complete removal of recast layers and micro-cracks from machining (like EDM or laser drilling) without compromising the delicate thin walls of the blade.The result is a dramatic improvement in surface finish (often achieving sub-Ra 0.1 µm),which is critical for reducing aerodynamic friction and preventing crack initiation under extreme thermal and mechanical stress.
Furthermore,it ensures optimal airflow and heat transfer efficiency within the cooling channels,directly contributing to enhanced engine performance,fuel efficiency,and unparalleled reliability.This leap transforms AFM from a mere finishing step into a critical,value-adding technology for next-generation propulsion systems.
