碩士 === 國立虎尾科技大學 === 機械與機電工程研究所 === 102 === Machine tool is an indispensable work of many machine tools, including vehicle industry、ship manufacturing、railway、electronic industrial machinery、 aircraft …etc。Not only increasing the accuracy requirements of the product，but also the accuracy requirements of the machine tool relative increase resulting that think about how we could improve the accuracy of machine tools。 This paper focuses on structural design problems machine tool spindleand experimental analysis of a spindle original design manufacturers to provide improved according to the manufacturer . A current problem is to find manufacturers spindle operation is not stable, and therefore how to prevent failure of the spindle and the spindle to reduce the incidence of failures, but also be able to quickly find out which part of the spindle failure. In this paper, namely the use of reliability engineering Spindle conducted on temperature, dynamic, pre-press, etc. experimental testing and measurement, and then analyzed according to the experimental data values and found that these factors affect the accuracy of the spindle, the proportion accounted for balancing is the highest, so we first major improvement for balancing, you can get quite a significant improvement.
