Principles Of Using Sandbelts

1 Choose the appropriate sand belt model

The selection of sand belt model varies depending on the material of the workpiece being processed, the shape of the workpiece being processed, and the grinding method used. The selection of sand belt model is mainly based on four aspects: the type of substrate, the material of abrasive, the type of binder, and the joint method of the sand belt. The selection of sand belt model should generally be completed professionally. As this aspect has already been introduced in domestic literature, this article will not elaborate further.

2 Choosing the appropriate granularity

Only by selecting the appropriate grit size of the sand belt can the surface quality of the processed workpiece be guaranteed and the service life of the sand belt be improved. If the selected sand belt particle size is too small, the surface quality of the processed workpiece cannot be guaranteed; If the particle size of the selected sand belt is too large, it not only fails to reflect the efficiency and economy of sand belt grinding, but also makes the sand belt prone to wrinkles and fractures during use, reducing its service life.

3 Particle size selection for multiple sand belt grinding processes

If a workpiece is ground using multiple sand belts, the particle size of the sand belt used in the later stage can only exceed two particle size numbers compared to the previous stage. Only in this way can the efficiency of belt grinding be maximized, and the shape, size, and surface quality of the processed workpiece be guaranteed.
