Fighter Aircraft in Abrasives - What are the Classifications of Flap Wheels

There are many kinds of flap wheels abrasives with various shapes and sizes. For example, the 1000 grit flap wheel produced by Riken Abrasives is a kind of popular abrasive cloth. According to different abrasives, binder materials and manufacturing processes of sandpaper wheels, each sandpaper flap wheel has a certain scope of application. Improper selection will directly affect the processing accuracy, surface roughness and production efficiency. Therefore, suitable grinding wheels must be selected according to the specific conditions when grinding.


Brown corundum flap wheels: brown corundum grinding wheel has high hardness and toughness. It is suitable for grinding metals with high tensile strength, such as carbon steel, alloy steel, malleable cast iron, hard bronze, etc. This kind of abrasive has good grinding performance and wide adaptability. It is often used for rough grinding with large margin removed. It is cheap and can be widely used.


White corundum flap wheels: The hardness of white corundum is slightly higher than that of brown corundum, but its toughness is lower than that of brown corundum. When grinding, the abrasive grains are easy to break down. Therefore, the grinding heat is small. It is suitable to manufacture grinding wheels for fine grinding quenched steel, high carbon steel, high speed steel and thin-walled parts, and the cost is higher than that of brown corundum.


Black silicon carbide flap wheels: Black silicon carbide grinding wheel is brittle and sharp, and its hardness is higher than white corundum. It is suitable for grinding materials with lower mechanical strength, such as cast iron, brass, aluminium and refractories.


Green silicon carbide flap wheels: Green silicon carbide has higher hardness and brittleness than black silicon carbide. The abrasive is sharp and it has good thermal conductivity. It is suitable for grinding hard and brittle materials such as cemented carbide, optical glass and ceramics.


Chromium corundum flap wheels: It is suitable for grinding workpieces with high surface processing quality, such as cutting tools, measuring tools, instruments, threads, etc.


Single crystal corundum flap wheels: suitable for grinding stainless steel, high toughness, high hardness materials such as high vanadium high speed steel, easily deformed and burned workpiece.


Microcrystalline corundum flap wheels: suitable for grinding stainless steel, bearing steel and special ductile iron. It is used for shape grinding, cut-in grinding and mirror grinding.


Zirconium corundum flap wheels: suitable for grinding Austrian stainless steel, titanium alloy, heat-resistant alloy. It is especially suitable for heavy load grinding.
