With PLC Reform M1420 Universal Cylindrical Grinding Machine Electrical Control System

Because many of the factory in the old ordinary grinder machine tool electrical part has been to use relay-contactor control and s is more long,the work has already can't satisfy the requirements of the modern industrial production,and because the lines of assembly and the wastage of the electrical components,the machine of the high failure rate.But directly eliminate the old equipment to replace new equipment requires a larger fee,if the relay-contactor control system of the old general grinding machine related renovation by using programmable controller to replace the relay-contactor,can save a lot of money for the enterprise.Also can make the precision of the machine tool and update development of the function fully,to realize the automation of machine tool control.Grinding machine is to use abrasive to grinding workpiece surface of machine tools.Most of the grinding wheel grinding machine is used to grinding,small grinding machine using abrasive,abrasive belt grinding tool and free abrasive machining.Grinding machine is a kind of the most abundant metal in many types of machine tool grinding machine,mainly can be divided into: internal grinder,surface grinder,cylindrical grinder,tool grinder,etc.Using PLC in the control circuit of M1420 type universal cylindrical grinder.To solve the old relay-contactor circuit lines that exist in the complex and difficult problems such as failure diagnosis and elimination,and reduces the failure rate of equipment.Because the PLC has high reliability,strong anti-interference ability,easy to learn,small volume,convenient operation,powerful functions.M1420 in modified with PLC type,therefore,universal cylindrical grinder can not only complete the functions and characteristics of the original,also can have very good stability,and easy to diagnose and repair after failure,etc.The focus of this design is to transform the M1420 type universal cylindrical grinder relay-contactor control circuit system into a PLC control system and the use of mitsubishi's GX Developer write PLC ladder diagram,programming software,after the completion of writing using the GX Simulator6-C mitsubishi simulation software simulation test,finally using GT Designer3 touch screen software simulation animation effects.
