Magnetorheological jet polishing (MJP) is a new deterministic precision finishing technology.

Nano-particle colloid jet polishing is a new kind of ultra-precision machining technology which has important research and application value in fabricating ultra smooth surface.

The results show that abrasive water jet polishing surface has a good effect and can improve the surface hardness, surface fatigue strength. The lower the surface hardness, more obvious the effect.
