So what should you pay attention to when polishing machines use sandpaper to polish?

The use of sandpaper polishing requires the use of soft club or bamboo rods, if the harder wood is more suitable for flat surface polishing, because the abrasive paper polishing is more suitable for the polishing of the spherical surface, because the spherical polishing used is the soft rod can very good cooperation spherical curvature;

If the use of different types of sandpaper, then the direction of polishing needs to be changed, the general change to 45°~90°; before changing the different sandpaper will see the previous use of sandpaper traces, then this use will need 100% of cotton with alcohol and so on the cleaning fluid before the traces, Because even a tiny particle can affect the rest of the work.
