Experimental study on the influence law of the number of processing cycles and abrasive concentration on the polishing effect of abrasive flow

Abrasive flow polishing technology finds extensive application in surface treatment for various high-precision components owing to its exceptional efficiency, precision, and versatile applicability. Both the number of processing cycles and the concentration of fluid abrasive are pivotal factors influencing the polishing efficacy of the workpiece. This study investigates the impact of both the number of cycles and the fluid abrasive concentration on the polishing outcome of tubular workpieces through abrasive flow polishing experiments. Experimental findings indicate that within the normal processing range, an increase in the number of cycles corresponds to an enhanced polishing effect. However, excessive cycles may result in over-processing, thereby detrimentally impacting the polishing outcome. Within a specific range, the polishing efficacy of abrasive flow is directly proportional to the magnitude of abrasive concentration. However, excessive concentration can elevate abrasive viscosity, impeding its fluidity and consequently influencing the polishing effect.
