As many of the factories' old grinders' work has been well below the needs of modern production,it's necessary for the old conventional motor control system to have technological transformation, with PLC to replace the conventional relays.Thus it will reduce the intermediate relay, the lines are simplified and improved the reliability,which will achieve the goal of automatic control of grinder.
First part gives a brief presentation about all the old papers on the electrical system Cylindrical Grinder and pointed out the shortcomings , then made a better rehabilitation programmes. The programme will improve the control on two aspects:control system's hardware design and software design. Some of these hardwares design introsuces the PLC Selection methods, I / O PLC and the schedule of the PLC external wiring diagram drawing, and software design part will begin with general steps of PLC programming, then made the PLC program design ideas and programmes, part of the process of analysis and mapping. After the transformation,the grinder will work safely and reliability, the system is running well, and get a higher precision grinding. With the use of PLC controllong,we'll meke the grinder start, stop, failure to stop, emergency stop function in automatic or 定程的（这词不会） ways.Such flexibility will be under the operational requirements of the control switch grinder to reach the goal of grinder running automatic control. Trough the PLC transformation of GZ066 Cylindrical Grinder, making this the old idle equipment to play the original features and new added features, enhance the value of the machine. Finally, the technology can also be applied to other auxiliary equipment or other areas of control in automation.
Key words:PLC/Cylindrical Grinder/PLC transformation
我也建议精简，觉得只写第一段就好。
