1. Loose and cracked sand belt joints, strengthening quality control in production to meet user needs

2. The tension of the sanding belt is too high, and the adjusted tension does not slip under working load. The smaller the tension, the better

3. During transportation or installation, the sand belt may be wrinkled or the edges may be damaged. The appearance quality should be checked before installation, and the correct operation should be followed during installation

4. Too much work pressure, reduce the pressure

5. Cutting too deep, accumulation of frictional heat, reduction of cutting depth or feed rate, or use of coolant or cooling devices

6. Dust removal is a good preventive measure for external debris entering between the sand belt, rollers, or plates

7. Excessive vibration of the sand belt, use low hardness contact wheels to check the vibration of the machine or the quality of the sand belt

8. Contact roller cone; The contact roller or graphite pad is not parallel to the base, and the grinding roller is used to remove the cone; Reinstall and keep parallel

9. The machine is not running properly, and the sanding belt is broken by the travel switch for maintenance equipment (pay special attention to paper-based sanding belts)

10. The difference in thickness of the workpiece is too large or there is partial overlap. The installation of impact sand belts is aimed at protecting overlapping plates and oversized parts with protective devices
