1. The sanding belt joints are not firm and cracked. Strengthen quality control in production to meet user needs.
2. The abrasive belt is wrinkled or the edge is damaged during transportation or installation. Check the appearance quality before installation and operate correctly during installation.
3. The belt tension is too high. Adjust the tension so that it does not slip under the working load. The lower the tension, the better.
4. Cutting too deep, friction heat accumulation, reduce cutting depth or feed speed, or use coolant or cooling device.
5. Too much work pressure, reduce the pressure.
6. External debris enters between the sanding belt and the roller or plate. Removing the debris and efficient dust extraction are the best preventive measures.
7. The machine is not running properly, and the abrasive belt is broken by the travel switch. Repair the equipment (pay special attention to the paper-based abrasive belt).
8. The abrasive belt vibrates excessively. Use a low-hardness contact wheel. Check the vibration of the machine or the quality of the abrasive belt.
9. The contact roller is tapered; the contact roller or graphite pad is not parallel to the base. Grind the roller to remove the tapered shape; reinstall to keep it parallel.
10. The thickness of the workpiece is too different or partially overlapped. The abrasive belt is installed to protect the overlapping plates and oversized parts.
