What is the principle of static before dynamic maintenance in precision parts processing

In the field of precision parts processing, repair refers to the operation of replacing old parts with identical new ones or processing and repairing old parts to ensure the normal and safe operation of CNC machine tools in use. These operations should not change the characteristics of CNC machine tools. The repair principles of CNC machine tools are static before dynamic, mechanical before electrical, external before internal, public before special, simple before complex, and general before special. Today, let's briefly talk about the part of 'quiet before moving.

Before moving, it is important for the maintenance personnel to remain stationary and not blindly engage in manual operations. During the processing of precision parts, the machine operator should first inquire about the process and status of the malfunction, read the machine tool manual, drawings, and materials, and then proceed with troubleshooting. Secondly, for malfunctioning machine tools, the principle of first being static and then moving should be followed. First, in the static state of the machine tool when the power is off, through observation, testing, and analysis, it can be confirmed that it is a non vicious cycle fault or a non destructive fault before powering on the machine tool. Under operating conditions, dynamic observation, inspection, and testing should be carried out to find the fault. However, for malignant and destructive faults, they must be dealt with and eliminated before powering on, Perform dynamic diagnosis during operation.
