摘　　要：通过分析T2120深孔镗床在对动车车轴进行深孔钻削中遇到的问题,找出了机床原控制系统存在的缺陷与不足,并根据用户目前的实际需求提出了由PLC控制的改造方案。该系统主要由PLC、触摸屏、变频器及伺服驱动组成,能够实现主轴的无级调速和刀具进给速度及深度的自动控制,保证了深孔加工工艺的灵活性,并使机床的加工精度和加工效率大幅提高,大大降低了车轴废品率。Through the analysis of T2120 deep hole boring machine in the moving car axle for deep hole drilling problems,finds out the flaws and shortcomings of the original machine control system,and puts forward a kind of automatic control reform scheme according to the user's actual demand. The system consists of PLC,touch screen,inverter and servo drive,can realize stepless speed regulation of spindle and tool feed speed and depth of the automatic control,ensure the flexibility of the deep hole machining process, and increase machining accuracy and efficiency greatly,significantly reduce the axle rejection rate.
