The aim is solving device complexity, inferior reliability and stability, malfunction analysis and trouble obviation of the traditional relay electric control system. Because of electric control system PLC there are lots of advantages which include design, install, connect the line and adjust to try workload small, the period of research and manufacture is short, reliability is high, the ability of Anti- interference is very strong, the rate of break down is low, the demand of work environment is low, maintenance convenience a series of advantage etc. Therefore, a work for to the Z3050 radial drilling machine electric control system reforming, will reforming PLC control technique application in the project, then increasing radial drilling machine’s work function. The paper introduces to the control principle of the radial drilling machine. Established the programmable controller improve the design project of electric control system of Z3050 radial drilling machine. Completed the design of the software and hardware of the electric control system, Among them include the model of PLC choice、the I/O allotment of the address、the I/O hardware connects the line diagram、PLC trapezium diagram’s design. It explains that PLC control the work process of radial drilling machine. Discussing the adoption PLC replaces the traditional electric control system’s method and increases the work function of radial drilling machine, give a homologous control principle diagram.
