5. Belt operation
When overlapping the sand belt, the operation direction of the sand belt should be aligned with the direction marked on the back of the sand belt, otherwise the sand belt is prone to premature fracture during the process and affects the appearance quality of the added parts.
Storage of sand belts is important, but if the sand belt is not properly handled before use, it will still seriously affect its performance.
Suspension of sand belt
The sand belt should be hung for at least 2-5 days before use to eliminate curling caused by packaging. Hang the unpacked sand tape on a 100-200mm diameter pipe or a dedicated sand tape support frame. The length of the pipe should be greater than the width of the sand belt, otherwise the sand belt may easily fall off or produce horns; The pipe should be in a flat state, otherwise it is easy to damage the edge of the sand belt. The environmental temperature and humidity of the suspended sand belt should meet the storage conditions of the sand belt. The simplest method is to keep it dry in a sealed room.
Visual inspection
The suspended sand belt should undergo necessary appearance quality inspection before use to check whether the sand belt joint is flat and firm; The surface of the sand belt has holes, sand balls, lack of sand, adhesive spots, and wrinkles; Check if the edges of the sand belt are neat and have cracks. If there are larger cracks on the edges, they should be cut off (in a circular shape) without affecting the use.
The use of sandbelts
Only by selecting and correctly using the abrasive belt can various problems that arise in the process be reduced, and the advantages of abrasive belt grinding and the optimal grinding performance of the abrasive belt can be fully realized.
