What is the maintenance of static first and then dynamic in the maintenance principle of precision parts processing

In the field of precision parts processing, repair refers to the operation of replacing old parts with the same new parts or processing and repairing old parts in order to ensure the normal and safe operation of CNC machine tools. These operations should not be Change the characteristics of CNC machine tools. The repair principles of CNC machine tools are static first and then dynamic first, mechanical first and electrical first, external first and internal first, public first and then dedicated first, simple first and then complex, general first and then special first. Today I will briefly talk about the part that is quiet first and then moving

Static first and then move. The maintenance personnel must be static first and then move. Do not act blindly. During the process of precision parts processing, you should first ask the machine tool operator about the process and status of the failure. You can only do it after reading the machine tool instruction manual and drawing materials. Find and handle the fault. Secondly, for faulty machine tools, you must also follow the principle of static first and then move. You must first wait until the machine tool is powered off. After observation, testing and analysis, it is confirmed as a non-vicious cycle fault or a non-destructive fault. Power on the machine tool, dynamic observation, inspection and testing are carried out under operating conditions, and faults are found. However, for vicious and destructive faults, it is necessary to deal with and eliminate the danger before powering on and dynamically diagnosed in operating conditions.
