酚醛层压布管保持架高精密加工工艺改进

摘要

The traditional processing technology is introduced for cages made of phenolic cloth laminated tube,and the main factors influencing accuracy and dimensional stability of products are analyzed.The process improvement scheme is put forward for the cages.It is determined that the high count phenolic cloth laminated tube is used,and the rough turning of inner,outer diameter surface and oil immersion process is added through process test.The precision of products meets requirements of P4,and the dimensional stability is improved.%介绍酚醛层压布管保持架传统加工工艺,分析影响其产品精度及尺寸稳定性的主要因素,提出了酚醛层压布管保持架工艺改进方案.通过工艺试验确定了采用高支数酚醛层压布管材料,增加粗车内、外径面和浸油工序,满足产品精度达到P4的要求,尺寸稳定性更高.
