Sanding machines have a wide range of applications, not only in the timber industry but also in many other sectors. Different types of sanding belts are needed when sanding different types of boards.

1. For example, 60# sanding belts can be used for sanding fixed-thickness floor substrates; one belt is sufficient. For sanding primer, use 320# sanding belts at a speed of 6-9 Hz.

2. For sanding water-based floor putty, use 100# sanding belts first, then 150# sanding belts. For fine sanding, use 240# sanding belts first, then 320# sanding belts.

3. Water-based paint flooring requires sanding textures that match the leveling requirements of the topcoat, meaning higher sanding precision. For 320# sanding, pay attention to adjusting the sanding belt speed and visually observe the sanding texture to adjust the sanding speed accordingly.

4. Adjusting the sanding machine according to different types of boards is essential to ensure high-quality products.
