Abstract: In this paper, the processing objects are the micro-shaft parts with sizes ranging from 0.5 to 5 mm in diameter and less than 30 mm long. Processing features and turning mechanism about micro-parts are studied in order to propose turning method about symmetrical processing with multiple-tool. Software CATIA is used to generate three-dimensional solid model for the overall layout structure of high speed miniature lathe, while finite element analysis software is used to achieve dynamic performance analysis, so as to obtain each factorial of machine-tool vibration and natural frequency. The result is important to machine optimisation and the construction of experimental prototype, and will guide the next work.
