摘　　要：分析了T68卧式镗床控制系统的主要功能和常见故障。针对控制系统存在线路复杂、可靠性差、故障率高等缺点,选用三菱FX3U-32MR为控制系统核心,通过PLC的I/O地址分配布置及外部硬件接线和梯形图程序设计,完成控制系统改造。经过运行调试,满足了企业实际生产要求,提高了镗床工作的可靠性。After an analysis of the main functions and common failures of the T68 horizontal boring ma- chine control system, the paper upgrades the control system to solve the problems including complicated cir- cuits, poor reliability and high failure rate, with Mitsubishi FX3U-32MR as its core, by allocating the I/O ad- dresses of PLC, wiring the external hardware lines and designing the trapezoidal chart procedure. After debugging ,the upgraded system meets the enterprises＇ actual production requirement, and improves the reliability of the boring.
