Fluid Jet Polishing

Hey Herbert,
Have you done any study of Fluid Jet Polishing ?? I ran across a description of ot while reading about bowl feed polishing, and started wondering what would give the absolute smoothest surface possible.

Hi Robert, that is an interesting grinding / polishing method.
It looks very useful for parts with odd shapes but the surface
roughness is not as good as it could be. I read two different
articles about the Jet Polishing one of them claimed a surface
roughness of 3.6nm and the other was 1nm . The material
was BK-7. You can easily get down to 1nm on BK-7 with
a pad or pitch polishing. When people refer to superpolishing
they are trying to get down in the area of 0.05nm - 0.20nm
depending on the material being polished.

I hope to purchase one of these machines in the next several years.

All the best,

Hi. Could one of these systems be used to "grind" out a proper figure in the first place? What about micro- or nano-scale particulates in suspension, or materials at the edge of solubility (salts for instance) which would just begin to crystallize as the jet hit the surface of the blank?

I had begun to think about this several weeks ago but put it aside- glad others are interested as well. Thanks.
