Mirror-jet polishing is a revolutionary technology that gives precision parts an ultimate smooth fin

What is a mirror jet polishing machine?

1、A mirror jet polishing machine is a precision polishing device based on fluid dynamics. It sprays a fluid (usually gas or liquid) mixed with fine abrasive particles at high speed onto the workpiece surface. The impact and micro-cutting action of the abrasive particles remove microscopic surface protrusions, achieving a polishing effect with nanometer-level roughness. Simply put, it's like gently polishing the surface with a "miniature sandstorm," leaving no marks but achieving an extremely smooth finish.

2、Unlike manual polishing or mechanical grinding, mirror jet polishing is a non-contact process, avoiding the risks of tool wear or surface damage. It is particularly suitable for processing high-hardness, brittle materials (such as ceramics and silicon wafers) or complex cavity structures.

Which industries will benefit most?

1、Precision mold manufacturing: Cavity polishing of injection molds and die-casting molds can achieve Ra ≤ 0.01 μm, significantly improving product demolding performance and service life.

2、Medical devices: Components such as surgical blades and artificial joints, after polishing, not only achieve a mirror-like finish but also enhance corrosion resistance and biocompatibility.

3、Optics and semiconductors: Ultra-precision machining of lens and wafer surfaces can reduce light scattering and improve device efficiency.

4、Aerospace: The fatigue strength of key components such as turbine blades and fuel nozzles can increase by more than 20% after polishing.
