A process to effectively remove machine lines blending the surface to a high luster uniform visual standard while reducing the surface roughness to below 8 Micro inches. The process does not remove or move the affected material greater than 0.02 mm, and the process is designed to produce a visually acceptable part that reduces surface roughness below 8 micro inches and holds tightly toleranced complex geometries.

A jet polishing device capable of stably forming a Gaussian removal function includes: an auxiliary mounting mechanism; a jet machining mechanism. The jet machining mechanism is connected with the auxiliary mounting mechanism, the jet machining mechanism includes a rotation driving assembly, a positioning assembly and a jet machining assembly, the positioning assembly includes a linear guide rail, a slide mass, a first laser and a second laser, the rotation driving assembly is connected with the linear guide rail, the slide mass is slidably connected to the linear guide rail, the first laser is fixedly arranged relative to the linear guide rail, the jet machining assembly includes a mounting bracket fixedly connected with the slide mass, a nozzle mounting body rotatably connected to the mounting bracket and a nozzle arranged on the nozzle mounting body, and the second laser is connected with the nozzle mounting body.
