Flap disc can replace resin needle wheel with high elasticity, excellent self-sharpening, high grinding rate and low noise, which is suitable for grinding and polishing for various stainless steel and carbon steel structural parts. With the latest design, the substrate can be completely separated from the abrasive discs, which is convenient for manual decoration and high efficiency and environmental protection.

The application of flap disc: Flat flap discs are mainly used for grinding and polishing for various stainless steel and carbon steel structural parts. Grinding flap discs are widely used in grinding, polishing, dressing, and rust removal processes in automobile manufacturing, heavy machinery, ships, stainless steel products, aluminum alloys, boilers, hardware and decoration industries.

The use of flap disc:

The flap disc can be used in various types of surface derusting, paint removal, deburring and grinding of welds in shipbuilding, automotive, aerospace, machinery, instrumentation, bridges and construction industries and furniture metal and non-metal materials. The substrate of the flap disc is mesh, nylon, plastic, steel paper, etc with the shape of fan evenly distributed . Flap discs are used for welds, grinding and grinding for positive burrs, interchangeable with burrs and can be interchanged with depressed center grinding wheel. They has the advantages of good elasticity, high efficiency, good heat dissipation and low noise. The hardness of flap disc is mainly determined by the amount of binder added and the density of the abrasive. The abrasive particles are easy to fall off and the abrasive hardness is low. On the contrary, the hardness is high. The hardness grades are generally divided into seven grades: super soft, soft, medium soft, medium, medium hard, hard and super hard grades, which can also be subdivided into several sub-levels. Methods for determining the hardness of abrasive tools commonly use hand taper method, mechanical taper method, Rockwell hardness tester and sandblast hardness tester.
