The flap wheel, also known as the chuck flap wheel, is a kind of coated abrasive. Each product is made of hundreds of gauze pieces bonded together, hence the name. It uses aluminum oxide as abrasive, and the base material is a cloth base made into gauze through an assembly line, and then the gauze is stacked and fully bonded with resin.
The flap wheel is suitable for large-area rough polishing, grinding, rust removal and grinding of various stainless steel, metal, wood and other fields, polishing and shaping of various irregular surfaces, rust removal and grinding of various aspects of mechanical manufacturing of different materials, with high polishing efficiency and long service life.
The hardness of the flap wheel mainly depends on the amount of binder added and the density of the flap wheel. The abrasive particles that fall off easily indicate low hardness; conversely, it indicates high hardness.
The hardness level is generally divided into seven major levels: super soft, soft, medium soft, medium, medium hard, hard and super hard, and these levels can be further subdivided into several small levels.
The methods for measuring the hardness of the flap wheel are the hand cone method, the mechanical cone method, the Rockwell hardness tester method and the sandblasting hardness tester method.
The hardness of the flap wheel has a corresponding relationship with its dynamic elastic modulus, which is conducive to using the audio method to measure the dynamic elastic modulus of the flap wheel to express the hardness of the abrasive tool. In the grinding process, if the material hardness of the workpiece is high, a flap wheel with low hardness is generally selected; otherwise, a flap wheel with high hardness is selected.
The flap wheel has the characteristics of high processing efficiency, high safety, and convenient continuous operation. It saves more time than manual grinding and is the best among abrasive tools. As long as you master the correct grinding method, you can bring a good user experience, and the grinding effect is also outstanding!
