[Purposes]This paper aims to improve the machining efficiency while ensuring the machining quality by using large pitch thread turning.[Methods]Taking the large pitch triangular thread as an ex-ample,the processing method was studied,and the analysis and test of different turning methods were re-ferred to and optimized.[Findings]Compared with the traditional processing method,the processing effi-ciency is improved by 2~3 times by using the numerical control turning triangular large pitch thread pro-cessing method.Through tool design,material selection,etc.,the problems existing in the CNC turning process of triangular large pitch threads are solved.Especially for the triangular thread with pitch of 4~6 mm,the production efficiency is greatly improved and the production cost is reduced under the premise of ensuring the quality of thread processing.[Conclusions]This study provides an important reference for CNC turning of large pitch triangular threads in the design of turning tools,and has the value of pro-motion.
