Numerical control machine tools are complex in structure and extremely high in science and technology. They are affected by many factors and are prone to various types of failures. The maintenance of electrical faults always takes fault diagnosis and troubleshooting as the basis. Combined with many years of practical experience, the editor of ULI-CNC believes that the following key points must be followed for electrical fault diagnosis:
From static to dynamic: In the process of troubleshooting and diagnosing electrical faults of CNC machine tools, the basic principle of safety first needs to be followed. After the electrical failure occurs, the maintenance personnel cannot do the maintenance immediately after arriving at the site. Instead, they first need to check the appearance of the machine tool, ask the actual situation found by the operator, and then analyze the factors of the failure, combining the results of observation and inquiry, Locate the general location of the fault, and then start troubleshooting one by one.
From simple to complex: When carrying out maintenance work on machine faults, staff need to fully understand the equipment, conduct accurate troubleshooting of the internal system, and simplify the process of fault diagnosis by understanding the operating parameters of the CNC machine tool, and improve the efficiency of fault diagnosis. When multiple electrical faults are found to be interlaced, it is necessary to start with simple faults first, and gradually in-depth diagnosis of complex faults.
From the outside to the inside: Today's CNC machine tools are generally large in scale. CNC machine tools usually contain a large number of control buttons and disassembly switches, and the operating environment is more complicated. Therefore, after the electrical failure of the CNC machine tool occurs, the staff often need to face more severe challenges. At this time, the maintenance personnel are required to start from the outside of the machine tool, gradually go deep inside, and carry out troubleshooting and diagnosis in order to improve the failure rate. Diagnosis efficiency lays the foundation for subsequent maintenance work.
From mechanical to electrical methods: After a CNC machine tool fails, mechanical faults are easy to be found. The maintenance personnel combined with practical work experience, through observation of the appearance of the machine tool, can roughly understand the problems existing in the mechanical structure, and then can carry out repairs in time Work. However, it is relatively difficult to troubleshoot electrical faults, so maintenance personnel first need to troubleshoot mechanical faults, and then diagnose electrical faults, so as to achieve the goal of improving work efficiency.
