(1) tens of thousands of Chinas current outdated and backward in mind the machine, these are major repairs and CNC machine tool industry in the transformation of the reality of survival one of the bases. (2) 20th century, a large number of imported second-hand CNC equipment has entered the maintenance and improvement of the peak. (3) And CNC machine tool equipment will cost a significant transformation of the economic benefits of the NC driving force for the development of the industry, the general transformation of the cost of the acquisition of new equipment only costs about 30%. (4) Through the NC can be further modified to meet user requirements for process equipment in order to obtain greater benefits. The purpose of this paper is the transformation of double-housing planer to PLC to enhance the efficiency of its work. PLC as a new type of control device with the traditional relay control systems with fast response time, reliability, and control procedures may change with technology, easy computer connectivity, easy maintenance, sm
