Recently, an advanced device based on abrasive flow polishing technology has attracted widespread attention in the precision manufacturing field. This technology successfully solves the surface finish challenges of complex internal cavities, intersecting holes, and irregularly shaped flow channels that are difficult to access using traditional methods.
Abrasive flow polishing, also known as fluid polishing, relies on a semi-fluid abrasive medium. During processing, the equipment applies strong pressure through a hydraulic system, forcing this abrasive, viscoelastic abrasive to flow through the interior or surface of the workpiece. As the abrasive passes through narrow channels or rough areas, it generates minute cutting action, similar to "microscopic rivers eroding rocks." Due to the abrasive's fluidity, it can uniformly reach all surfaces, including every corner and deep hole, achieving uniform polishing from coarse to fine, ultimately reaching a mirror finish.
This technological breakthrough significantly improves the performance and lifespan of key components such as fuel injectors, medical devices, and thread cutting tools, marking a new stage in high-precision parts processing.

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!
