Research on the technology of ultrasonic abrasive flow machining of zirconia ceramics

Abstract

This paper adopts the method of ultrasonic-assisted abrasive flow precision machining to study the ultrasonic-assisted abrasive flow precision machining of high-performance ceramics. Taking zirconia ceramic tubes as the research object, the influence laws of different inlet pressures, abrasive concentrations, and ultrasonic frequencies on the precision machining effect of high-performance ceramics are analyzed. The laws of ultrasonic-assisted abrasive flow precision machining of high-performance ceramics under different inlet pressures, abrasive concentrations, and ultrasonic frequencies are obtained. Through orthogonal experiments on the ultrasonic-assisted abrasive flow precision machining of high-performance ceramics, it is found that ultrasonic-assisted abrasive flow precision machining can effectively remove the strip-shaped grooves, protrusions, and depressions on the inner surface of ceramic tubes. The inner surface roughness Ra of the ceramic tube can reach 0.101 μm, which can effectively improve the surface quality of the inner surface of the ceramic tube. It is proved that ultrasonic-assisted abrasive flow can precisely machine high-performance ceramics, providing technical support for ultrasonic-assisted abrasive flow precision machining of high-performance ceramics.
