The study of polishing and equipment of abrasive flow

Abrasive flow processing is a new kind of surface polishing technology which is widely used for processing complex cavity parts. This paper will systematically illustrate an outline about abrasive flow technology. In addition, it also dedicated to introduce the principle of processing as well as the development & application of abrasive flow. Furthermore, based on the study of Ultra-Precision polishing of the Micro-hole nozzle of the engine, a micro-hole flow polishing device was developed; the abrasive flow polishing fluid was prepared and the test of surface roughness for the micro-hole nozzle before polishing was finished successfully. At last, this paper takes effort to test the ultra-precision polishing of the abrasive flow nozzle.
