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 along surfaces of the workpiece—entering from one end and exiting from the other—to achieve precise polishing and effective deburring.

The machine is highly versatile, making it suitable for polishing various curved flow channels as well as deburring intersecting or cross-drilled holes.

We also provide customized solutions and equipment tailored to your specific product requirements, ensuring optimal performance that meets your technical needs.

Working Principle

This innovative fluid polishing machine is specially developed for irregular workpieces such as plastic molds, hot nozzles, hot runners, long tubes, and bent pipes. Controlled by a PLC system, it achieves automated, economical, and highly efficient polishing.

The polishing marks are aligned with the functional direction of the workpiece, resulting in consistent, unidirectional surface finishing. This method is particularly suitable for complex shapes such as contoured surfaces, curved channels, multi-holes, micro-holes, and long holes—geometries that conventional tools cannot easily reach.

To meet customer demands, we provide customized unidirectional abrasive flow polishing machines and related services. We also offer subcontracting services for flow channel finishing, cavity and micro-hole repair, and internal polishing and deburring of workpieces with micro, multi, long, or irregular holes.

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