摘　　要：为了解决热咀薄壁套零件能够快速完成数控车削加工,根据零件加工要求,本文确定了合理的数控车削工艺,选择了合适的夹紧方案、刀具类型,并确立了高效的切削加工参数,确保加工任务顺利进行。通过数控车削试车加工,当主轴转速为2000 r/min,背吃刀量为0.15 mm,进给速度为0.08 mm/r时,达到了图样上的设计要求。采用合理的数控车削加工工艺、软卡爪辅助装夹以及涂层硬质合金刀具,不仅保证了零件的加工尺寸和表面质量,还有效防止了零件变形,提高了生产效率,为类似零件的加工提供了实际依据。To address the challenge of rapidly completing CNC turning for the hot-runner thin-walled sleeve component,this paper formulated a reasonable CNC turning process based on the machining requirements of the part.Appropriate clamping solutions,tool types,and efficient cutting parameters were selected to ensure the smooth progress of the machining task.Through CNC turning trial machining,when the spindle speed was 2000 r/min,the depth of cut was 0.15 mm,and the feed rate was 0.08 mm/r,the design specifications on the drawings were met.The adoption of a reasonable CNC turning process,soft-jaw auxiliary clamping,and coated cemented carbide tools not only guaranteed the machining dimensions and surface quality of the part but also effectively prevented part deformation,enhancing production efficiency.This paper provides practical evidence for the machining of similar components.
