And the use of PLC in double-sided milling machine for automatic control, can obtain very good effect, make its industrial production more economical and reliable and adapt to the requirements of social productivity now. Design based on PLC double-sided milling machine, automatic control system is introduced in the aspects of system hardware and software design idea, to FX2N - 48MR PLC as the core, to construct a automatic control hydraulic station, using four motor based action requires meet subject, reasonable utilization of limit switch function, single control of double-sided milling machine. Hardware aspects, in view of the main circuit and control circuit, auxiliary circuit three parts, respectively, make its studies to meet the development needs of modern efficient production, according to the three main action sliding sets, namely fast into, work into and retreat quickly, using different electromagnetic valve respectively in electricity situation action control, and whether the solenoid switch movement, have electricity depends on when only switch meet that makes PLC can executes programs; Software, use FXGP/WIN - SWOPC - C programming software
