You can choose based on the following points:


1. Number of blades


As the number of blades increases, the cutting force will increase, but the polishing effect may become worse because as the number of blades increases, the angle of blade insertion will be higher, and the polishing effect will be rougher compared to low angle blades.


If you don't care about the polishing effect, the lifespan and cutting efficiency of flat sandcloth wheels with a large number of blades are relatively high.


2. Service life


Generally speaking, the factors that affect the service life of flat sandcloth wheels include blockage, dullness, and sand loss. To solve this problem, the correct flat sanding wheel should be selected based on the hardness of the material being polished, the polishing pressure, and the size of the polishing amount:


(1) Under lower polishing pressure, choose ordinary cotton fabric as the backing material.


(2) Under high polishing pressure, choose polyester backing material as the backing.


3. According to the polishing amount, the hardness of the sand, the hardness of the ridge, and the durability


The progress of sand, 3M Cool cut ceramic alumina>zirconia corundum>silicon carbide>alumina


In addition, silicon carbide ore is less commonly used on louvers due to its higher price compared to alumina, but its durability is not as high as alumina, resulting in lower cost-effectiveness.
