In this paper, the electrical maintenance technology of CNC machine tools is briefly summarized, and the composition of the electrical system of CNC machine tools is briefly described. Some common faults are classified, and some common diagnosis methods of electrical faults of CNC machine tools are listed. This paper summarizes the electrical maintenance methods and skills of CNC machine tools, which enables maintenance personnel to diagnose and maintain the electrical parts of CNC machine tools in an orderly manner, reduces the diagnosis time of electrical faults and accelerates the maintenance speed of electrical faults. Key words: numerical control machine tool, electrical fault, analysis and maintenance preface With the development of electronic technology and automation technology, the application of numerical control technology is more and more extensive. Numerical control equipment based on microprocessor and marked by large-scale integrated circuits is produced, introduced and popularized in large quantities in China, which creates conditions for the development of machinery manufacturing industry and brings great benefits. But at the same time, because of their advanced nature, complexity and high intelligence, the maintenance theory, technology and means have changed greatly, and so have their maintenance theory, technology and means. In addition, any numerical control equipment is a process control equipment, which requires it to work accurately at every moment of real-time control. Any part of the fault and failure, will make the machine stop running, leading to production interruption. Therefore, it is very necessary to maintain the CNC system, which has complex principle and precise structure. Especially imported CNC machine tools, most of them cost hundreds of thousands to tens of millions of yuan. In many industries, these devices are in a key position, and if they are not repaired and eliminated in time after failure, they will cause great economic losses. There is still a big gap between the current maintenance situation in China and the design and manufacturing technology level of imported equipment, and China has not yet formed a mature and complete theoretical system on the electrical maintenance technology of CNC machine tools, which brings a lot of inconvenience to the maintenance and diagnosis of CNC machine tools. Therefore, it is impossible for an article in the form of a lecture to fully express the theory of electrical maintenance technology of CNC machine tools. This paper only summarizes the experience of many predecessors in order to properly sort out the subject. Directory: 1. Overview of electrical control system of CNC machine tools II.

Modern CNC machine tools are developing in the direction of large-scale, complexity, automation, high-speed and continuity, and their electrical systems are becoming more and more complicated. It is becoming more and more difficult to maintain the electrical fault of CNC machine tools, and the requirements for electrical fault diagnosis technology are getting higher and higher. Using advanced fault diagnosis technology to monitor and diagnose CNC machine tools can find machine tool faults in time, eliminate hidden dangers of accidents and prevent malignant accidents of equipment. And with the rapid development of high technology, the electrical maintenance technology of CNC machine tools will continue to improve and mature. ..................................................................................................................................................................................
