Abstract
The bearing pre-tightening force on the guide of high speed punch press has immediately influenced the running accuracy of the slide, as well as the precision of the high speed punch press. So, the control of bearing pre-tightening force on the guide of high speed punch press was a very important issue in the study of high-speed presses. Through the research and analysis of the guidance system structure, the method of adjusting and controlling the guide rail bearing pre-tightening up force has been proposed in this article.
