A very straightforward verification technique is to listen to the sound of the carving and milling machine's operation to determine whether the cutting tools of the grinding tool carving and milling machine are worn to a certain extent and the amount of wear. If the processing sound is very loud or harsh, introduce the abnormal processing condition of the cutting tools. At this time, a brief analysis can be conducted. If the quality of the cutting tools themselves is questionable (such as the abnormal noise when a new tool is being processed) or the tool clamping is questionable (the processing sound does not improve after the tool is re clamped) When there is a question about the tool parameters (precise cutting amount, reduced feed rate, and no significant improvement in machining sound), it should be possible to verify that the tool is worn and needs to be stopped for machining. The engraving and milling machine tool needs to be replaced.
In addition, the wear of the cutting tools can also be verified by the operation status of the engraving and milling machine during processing. If the processing parameters, cutting amount, and other configurations are reasonable, and the machine tool vibrates greatly during processing, making a buzzing sound. At this time, it can be determined that the cutting tools have reached the continued wear status, and if necessary, the engraving and milling machine tools need to be replaced immediately.
Hands on is an essential skill that repair personnel must possess. However, for repairing CNC machine tools with such precision and equipment, it is essential to have a clear goal, complete thinking, and meticulous operation. Before starting the operation, careful consideration and investigation should be conducted, and the starting point should be identified. During the operation, it is even more important to keep records, especially for the placement position of electrical components, wire numbers, machine parameters, adjustment values, etc., which must be clearly marked for easy recovery.
After the repair is completed, the "finishing" work should be done well, such as placing the machine tool, system casing, and fasteners in place; tidying up the wires and cables, etc.
When repairing the system, special attention should be paid: certain modules in the CNC system require battery maintenance for reference, and these boards and modules should not be inserted or removed at will; It is even more important not to change the components and setting terminals in CNC systems, servo drives, and other components without inquiring about the use of electronic components. Adjust the potentiometer position and change the settings to avoid more tense results.
