The machine equipped with a hydraulk cylinder,pumps the abrasive fluid up and down through the part to be processed to achieve polishingon the surface through an inner hole,burr ingand chamfering.
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!
Amirror su rfis achieved by the circulating polishing fluid and isespecially suitable for concave and convex surfaces and complex curved channels.Most suitable for gas and liquid fluid conduction tube.The method effectively improves the performance of the die or workpiece and achieves a bright and clean surface,the processed surfaceroughness can reach Ra0.025Ra0.01 microns.
Abrasive flow polishing technology is rapidly becoming a key process in the ultra-precision manufacturing of medical devices. For products requiring extremely high surface quality, such as precision parts for surgical robots, complex internal cavities in implants, and micro-medical devices, traditional polishing methods often struggle to meet the stringent standards of zero dead angles, scratches, and residue.

Abrasive flow technology leverages its flexible flow properties to allow the abrasive medium to perfectly adapt to various curved surfaces and microchannels, achieving uniform machining across the entire surface.
This process efficiently removes micron-level burrs and achieves an ultra-smooth surface without compromising workpiece precision. This highly consistent polishing not only significantly improves the reliability and service life of medical devices, but also effectively reduces the risk of bacterial carryover and biofilm formation, providing a solid foundation for their biocompatibility and safety.
As the technology continues to mature, abrasive flow is playing an irreplaceable role in the manufacturing of high-end medical products such as surgical blades, joint implants, and micro pumps and valves.
