Product Features

This fluid polishing machine uses a specially formulated abrasive media as the grinding medium. Under pressure, the media flows unidirectionally through internal holes or over surfaces of the workpiece—entering from one end and exiting from the other—to achieve effective polishing and deburring.

The machine is highly versatile and can be used for polishing various curved flow channels as well as deburring intersecting and cross-drilled holes.

We also offer customized solutions and equipment tailored to your specific products, ensuring our system meets your technical and production requirements.

Working Principle

This technology was developed specifically for irregular workpieces such as plastic molds, hot nozzles, hot runners, long tubes, and bent pipes. It is a new-generation fluid polishing machine capable of automatic, economical, and high-efficiency operation through PLC control.

The polishing marks produced are aligned with the functional direction of the workpiece, resulting in consistent and directional surface finishing. This makes it especially suitable for complex geometries such as uneven surfaces, curved channels, multi-holes, micro-holes, and long or irregular holes—areas that are typically inaccessible to conventional tools.

To meet diverse customer needs, we offer fully customized unidirectional abrasive flow polishing machines and related services based on product specifications.

We also provide subcontract services for companies or individuals, including flow channel polishing, cavity and micro-hole repair, and internal polishing and deburring for micro, multi, long, or irregular holes.

This process can improve component accuracy by up to three levels within minutes, achieving surface roughness as low as Ra < 0.015 μm.
