Abstract

In order to design the machine tool successfully, the analysis and evaluation of the essential parts should be performed after the products designed and before the prototype finished. The spindle assembly and headstock are the essential parts of High Speed machine tool, whose characteristics will affect the final performance of the machine tool directly. So it is very important to analyze the dynamic characteristic of the headstock and study the effect to machinery function. This paper's research is based on CHH6125 machine tool produced by Shenyang No.1 Plant of Machine Tools. The spindle of machine tool is motorized spindle. The Finite Element Analysis on headstock has been made to confirm its thermal transfer characteristics. Then the results of the Finite Element Analysis will be validated by some experiments later.
