高档数控机床高性能、高质量和机床零件制造水平与工艺存在密切相关性,而数控机床中的一个大件就是滑枕,滑枕的制造工艺在很大程度上影响着数控机床的性能与精度。而且作为一种大型铸铁件,滑枕在实际生产制造中很容易发生缩孔、裂纹以及念砂等问题。为此,本研究为设计高档数控机床滑枕铸造工艺,采用计算机软件对滑枕铸造工艺进行模拟,对工艺参数进行全面优化,不断提升高档数控机床滑枕铸造水平,同时探究高档数控机床滑枕铸造中立浇底柱底部雨淋浇筑对其性能的影响,以此为类似的机床铸件生产与制造提供有效借鉴。

high-performance high-end CNC machine tools,high-quality and machine parts manufacturing and technology level there is a close correlation,and digital control machine is a large ram,ram manufacturing process greatly affects CNC machine tools performance and accuracy. But also as a large cast iron ram in the actual manufacturing are prone to shrinkage,cracking and read sand and other issues. In this study,the design of high-end CNC machine tools ram casting process,the use of computer software to ram casting process simulation,optimization of process parameters to conduct a comprehensive,high-end CNC machine tools and improve ram casting level,while high-end CNC machine tools to explore the ram neutral bottom pouring casting pillar pouring rain on the properties,in order to provide an effective reference for similar casting machine production and manufacturing.
