Problems solved by technology

[0002] At present, there are many kinds of polishing abrasives used in the market, most of which are abrasive paper, which is commonly known as sand skin, which is a kind of material used to grind the surface of metal, wood, etc. to make it smooth and clean. It is made of grinding sand, and the base material is mostly made of paper material or single-layer cloth or film. The paper material is not soft enough when used, the paper base is easy to be brittle and damaged, and it is easy to rot when exposed to water. It is easy to scratch and polish when using equipment; while using a single layer of cloth or film as a base material is easy to wear, especially for equipment with a rough surface, the loss is greater, and it is very undurable. Generally, the item is roughly ground before fine grinding , Each time you polish an item, you need to use different types of sandpaper for rough grinding and fine grinding, which is troublesome to replace, and you need to replace two kinds of sandpaper, which increases the cost;
