Choosing the right sandpaper can solve a variety of problems and issues encountered during use. High-quality polishing sandpaper can demonstrate its superiority and chip resistance during grinding, ensuring the quality of each workpiece being processed. So, what are the principles for using polishing sandpaper?
First of all, you need to choose the sandpaper model reasonably
Different workpiece materials and shapes require different sandpaper models.
Selecting sandpaper models depends on four key factors: the base material, the abrasive material, the type of binder, and the attachment method.
Secondly, sandpaper appearance inspection
Before use, inspect the polishing material sandpaper after it's been hung to ensure that the joints are smooth and secure. Check the surface of the sandpaper for missing sand, glue spots, holes, sand clumps, or wrinkles. Also, check the edges of the sandpaper for any cracks or creases. If there are any minor cracks, remove them (cutting them into a rounded shape) to ensure they do not affect use.
Finally, choose the sandpaper grit size reasonably
Only by choosing the right particle size can the surface quality of the workpiece be guaranteed and the service life of the sandpaper be increased.
