CNC lathes play an important role in the machining industry,whether it is the production of threaded parts,or the production of shaft parts,CNC machine tools are the first to bear the brunt,and have the advantages of easy operation,high efficiency and high precision.At this stage,there is still a lot of room for improvement in the processing quality of CNC lathe parts.To further improve the quality of parts with high machining accuracy and non-standard shape,it is necessary to effectively adjust the CNC lathe.In this paper,by analyzing the relevant influencing factors of CNC lathe high-precision parts machining,effective control measures for the machining quality of high-precision parts are proposed.
