Lubrication system is got such a wide range of applications, is mainly because of the friction between mechanical devices are too damaged mechanical itself, lubrication system can help protect so as not to cause too big damage. Lubrication system design and machine commissioning and maintenance, to improve the machining precision machine tools, prolong service life and so on, all have very important role. But in the lubricating system of electrical control, still exist in the following problems: one is the lubrication system working condition monitoring. CNC machine control system in general only a tank oil noodles monitoring, in case oil-supplied insufficient, and for lubrication system easy appear oil, fuel blockage phenomenon, cannot make timely response. 2 it is setting of lubrication oil of circulation and give time onefold, easy to cause the waste. Nc machine tools in different work condition, need lubricating dose is different, such as in the machine tool suspended stage than processing stage need lubricating oil amount to little. In view of the above situation, on the nc machine, electric control system for lubrication control parts were improved design, the time monitoring lubri
