Through experiments, the micro-feeding mechanism of ultra-precision turning piezoelectric ceramics has been studied. The paper analyzes the micro-displacement characteristics of piezoelectric ceramics and gives the design method and performance of the whole mechanism. The experimental results show that the resolution of the micro-feed mechanism reaches 0.025μm, the frequency response range of 0 ~ 200Hz, to meet the needs of ultra-precision turning.
