Product Features

This fluid polishing machine utilizes a specially formulated abrasive media as the grinding medium. By applying pressure, the abrasive media flows back and forth through internal holes or across the surfaces of parts, repeatedly grinding to achieve polishing and deburring effects.

This type of fluid polishing machine offers a wide range of applications—from mold and gear polishing to deburring of small components, and more.

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

Working Principle

This technology employs vertical hydraulic cylinders to apply pressure on both ends, forcing the soft abrasive media to flow through the machined surfaces, internal holes, or edges of the workpiece. This process performs deburring, chamfering, and polishing through a reciprocating motion. 

It is particularly effective for mirror-finishing operations, especially on complex geometries such as concave-convex surfaces and curved internal channels where conventional tools cannot reach. 

This method is especially ideal for internal polishing of gas and liquid flow channels, aligning the abrasive marks with the direction of fluid flow. It significantly enhances the performance and quality of molds and workpieces, achieving ultra-smooth surfaces up to mirror-grade finish. 

After processing, surface roughness can reach as low as Ra 0.025 to Ra 0.015 µm, effectively improving surface quality and extending the lifespan of the component or mold.
