Title CA6140 lathe processing flange and the main process equipment design [资料来源:THINK58.com]
Abstract
Flange is a generic name,usually refers to that in a similar discoid metal body surrounding the opening of the hole with a few fixed, it’s used to connect other things. Flange connection in a wide range of application of mechanical, So it looks strange. This article is mainly directed against flange CA6140 lathe processing technology and the main hole of the process and equipment design on.you can learn flange of the entire structure and its process and notes through this article. Second through this question that you can from the side of the main procedures for fixture design. Finally, there are parts for the processing of a combination of machine tool design. From the choice of components to determine the processing parameters, this article reflects the current market value of the parts, as well as prospects for development.
