The application of CNC machine tool maintenance has not only brought revolutionary changes to the traditional manufacturing industry, and turned the manufacturing industry into a symbol of industrialization, but also with the continuous development of CNC technology and the expansion of application fields, it is an important industry for the livelihood of the national economy and the people. (IT, transportation, light industry, medical, etc.) The progress plays an increasingly important role, because the digitization of the equipment required by these industries has become the major development direction of modern progress.
The key to the maintenance of CNC machine tools is the diagnosis of the fault, that is, the search for the source of the fault and the location of the fault. Generally speaking, different fault diagnosis methods are used according to different fault types as appropriate. These parts of the CNC machine tool will inevitably have different degrees and types of failures, which will cause the CNC machine tools to not work normally. These factors probably cover mechanical corrosion, wear, and loss of effectiveness. Components are aging, destroyed, and failed electrical components, poor contact with connectors. Background changes such as current or voltage fluctuations, temperature fluctuations, hydraulic pressure and flow fluctuations, and oil pollution. Interference and noise software procedures are lost or damaged, etc.
