Sanding belts are coated abrasives and are called flexible abrasives. It is more flexible and safer than solid abrasive wheels in polishing, and has the advantages of higher precision and lower grinding cost.
Belt grinding is a form of coated abrasive grinding. The first sandpaper appeared in the world as early as 1760, but it was limited to manual operation at that time. It was not until 1900 to 1910 that the era of mechanical use of sandpaper and abrasive cloth was entered, and it was first applied to the wood industry in the form of a ring-shaped belt, and this mechanical grinding method using a ring-shaped belt abrasive cloth was the prototype of abrasive belt grinding. after 1930, abrasive belt grinding gradually developed to metal processing, and in World War II, the United States took the lead in using abrasive belt grinding in the manufacture of armaments, achieving obvious results. At the beginning of 1950, the emergence of the electrostatic sand planting method pushed belt grinding to a new stage, and the application of belt grinding gradually became common. Later, Europe and Japan also carried out research and application of abrasive belt grinding technology, which gradually developed into an independent processing technology field with complete categories and technical systems. Fuji star coated abrasives inc as one of the top-level companies in this industry, we are confident about our products and services.
Similarly to abrasive net，abrasive belt is a belt tool made by bonding abrasives to paper, cloth and other flexible materials for grinding and polishing. The basic components are: substrate, abrasive and binder, which together are called the three elements of abrasive belts.
Sanding belts are classified into cloth sanding belts, paper sanding belts and cloth-paper composite sanding belts according to the different substrates used. General sanding belts have joints in the substrate, and some have cloth sanding belts that are specially woven into a ring-shaped belt without joints.
