In the process of using a wood cnc router, it is inevitable that some wear will occur on the tools. Once the tools of the wood cnc router are severely worn, it will seriously affect the engraving accuracy of the wood cnc router, and thus affect the engraving effect of the wood cnc router. So, is there any way to let us know the tool wear of the wood cnc router in advance so that we can replace the tools in time and reduce the impact on the engraving work.

1. Listen to the sound of the wood cnc router when it is working, and pay attention to whether there is any harsh abnormal sound;

2. Listen to the sound of the spindle of the wood cnc router, and observe whether the spindle is holding back obviously;

3. Pay attention to the vibration during the processing of the wood cnc router, and see whether the vibration frequency and amplitude have increased significantly, and whether the machine tool spindle also has obvious vibration;

4. Observe the processing effect of the wood cnc router, and see whether the processed bottom knives are good or bad.
