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 important Suitable 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 explosive expansion of the New Energy Vehicle (NEV) industry,encompassing electric (EV) and hybrid vehicles,is becoming a primary catalyst for growth in the abrasive flow machining (AFM) market.
This surge in demand is directly linked to the critical role AFM plays in manufacturing two key high-volume components: electric drive units and battery systems.
Within the EV's core,the e-motor housing requires precise deburring and polishing of its intricate internal channels that facilitate coolant flow.Any burrs or surface imperfections can cause catastrophic failure in the insulated gate bipolar transistors (IGBTs) or reduce cooling efficiency,leading to thermal overload.
Similarly,the complex micro-channel plates used in battery cooling plates must be absolutely free of obstructions and have a smooth surface to ensure optimal thermal management—a non-negotiable factor for battery safety,performance,and lifespan.AFM is the only technology capable of reliably and consistently finishing these complex internal geometries at production volumes.Consequently,NEV manufacturers and their Tier-1 suppliers are driving unprecedented demand for high-volume,automated AFM systems.
This shift is moving AFM beyond its traditional niche in aerospace and medicine into the heart of high-volume automotive manufacturing.The market is responding with advancements in faster cycle times,automated loading/unloading,and more robust media formulations capable of processing millions of parts.This symbiotic relationship positions the abrasive flow market for significant and sustained growth,fueled by the global transition to electric mobility.
