Sandpaper rolls are pasted with double-sided tape, and then placed on a punching machine and cut with a special circular mold. Its shape is a perfect circle, so it is called disc sandpaper, which is essentially sandpaper. It is separated into multiple types according to the different bonding objects, sizes, sand surfaces, etc.
According to different bonding objects, it is divided into adhesive disc sandpaper and velvet disc sandpaper, as well as those with holes and those without holes. When grinding objects, the disc sandpaper with holes can discharge waste from the holes to improve the grinding efficiency.
According to the size, it can be divided into: 4 inches, 5 inches, and 6 inches.
According to the classification of sand surface, it can be divided into: white sand surface, red sand surface, yellow sand surface, blue sand surface, green sand surface and other disc sandpaper.
There are also classifications based on the raw materials of disc sandpaper, which can be divided into silicon carbide disc sandpaper and brown aluminum oxide disc sandpaper. Silicon carbide disc sandpaper can be divided into green silicon carbide disc sandpaper and black silicon carbide disc sandpaper. Brown aluminum oxide disc sandpaper can be divided into ordinary brown aluminum oxide disc sandpaper, calcined brown aluminum oxide sandpaper, iridium-plated brown aluminum oxide disc sandpaper, semi-brittle corundum disc sandpaper, etc.
