[0002] The flap wheel, also known as the thousand-leaf wheel or the chuck-type flap wheel, is a type of coated abrasive. Each product is made of hundreds of gauze pieces bonded together, hence the name. It uses aluminum oxide as the abrasive, and the base material is a cloth base that is made into gauze through an assembly line, and then the gauze is stacked and fully bonded with resin. Grooves are opened on the upper and lower chucks to fix the sand blades between the upper and lower chucks. L-shaped buckle grooves and fastening rings are respectively set at both ends of the inner side of the sand blade. The fastening ring is fixedly connected to the buckle groove, and the fastening ring is cured and bonded to the buckle groove through glue to form a thousand-leaf wheel. The flap wheel is divided into two types: straight groove and U-shaped groove.
