基于55°密封管螺纹的锥螺纹数控加工研究

Research on Tapered Thread NC Machining based on 55 ° Sealing Pipe Threading

通过对我国管螺纹现行标准、作用、工艺及功能特点的详细介绍,探讨了以数控加工的方式进行55°密封管螺纹的圆锥外螺纹的加工思路、工艺参数选择及程序编制。通过对55°密封管螺纹的数控加工工艺的研究发现,数控加工管螺纹不但可以提高加工精度及加工效率,而且在切削过程中选择适当的切削用量,可以较好地保证加工质量。

Through the detailed study of existing standards, role of pipe thread, process and functional features of pipe thread In our country, Discussions on conical outer thread of 55 ° sealing pipe threads Processing thoughts.process parame- ter selection and programming in NC machining were did. Through the study of 55 ° sealing pipe threads on NC machining process, NC pipe thread can increase accuracy and efficiency, and selecting the appropriate cutting amount in cutting process can ensure quality better.
