内容简介：

摘 要本文介绍了用可编程序控制器来对平面磨床 M7120 控制系统进行现代化改造。改造后的磨床工作安全可靠，系 统运行情况良好，磨削精度更高；利用 PLC控制磨床运行，实现了磨床启 动、停止、故障停止的功能，并且有手动控制和自动控制两种控制方式，可根据运行要求灵活切换磨床的控制方式；提供过载，轻载，断相和电压不平衡保护 ；现场显示运行状态， 实现 智能化监控。 实现了磨床运行的自动化且使原机床控制大大的简单化,并且维修方便,易于检查，工作效率更高。关键词：PLC ，平面磨床，改造 Based on PLC Surface Grinding Machine Automatic Control Systems TransformationAbstractThis paper describes that use PLC to modernize the surface grinder machine M7120s control systems. After the transformation of the grinder , the system is work safety and reliability ,running well as well as higher precision grinding .Using PLC control grinding machine running, and the grinder start, stop, failure to stop the function, and the manual control and automatic control , Under the operational requirements switches the way of the Control method flexibly ; provide over-load, light-load, loss of phase and the imbalance protects of voltage, demonstrate the state of the running scene and intelligent control. Grinder has realized the automation working and the control of the original machine greatly simplified and easy maintenance, easy to check, work more efficient. Key words: Progammabl
