Cheap Brown Fused Alumina Factory South Korea

There are many types of brown aluminum oxide grinding wheels, and there are various shapes and sizes. According to the different materials of the grinding wheel, the bonding material and the manufacturing process, each grinding wheel has a certain scope of application. Improper selection will directly affect the brown aluminium oxide manufacturer processing accuracy, surface roughness and production efficiency.

Therefore, when brown aluminium oxide grinding, you must choose the appropriate grinding wheel according to the specific situation. So how to choose the correct grinding wheel? The grinding wheels commonly used in grinding are summarized so that everyone can clearly choose the grinding wheel. The particle size refers to the particle size of the brown fused alumina for grinding abrasive, and its size is expressed by the particle size number.(cheap brown fused alumina factory south korea)

The choice of honing abrasives The choice of abrasives mainly depends on the black corundum workpiece material and heat treatment method. When grinding materials with high tensile strength, use tough abrasives. For materials with low grinding hardness and large elongation, use brittle abrasives. When brown aluminum oxide blast media grinding hard materials, use harder abrasives. Use abrasives that are not prone to chemical reactions in the material being processed.

(cheap brown fused alumina factory south korea)The most commonly used abrasives are brown fused alumina (A) and white alumina (WA), followed by black silicon carbide (C) and green silicon carbide (GC). Black silicon carbide is brittle and sharp, and its hardness is higher than that of white alumina. It is suitable for grinding materials with low mechanical strength, such as cast iron, brass, aluminum and refractory materials. This abrasive has good grinding performance and wide adaptability. 

The remaining commonly used are chromium corundum (PA) and single crystal corundum (SA). , Microcrystalline Corundum (MA), Zirconium Corundum (ZA). Brown corundum has high hardness and toughness, and is suitable for grinding metals with high tensile strength, such as carbon steel, alloy steel, malleable cast iron, hard bronze, etc. It is often used for cutting. Large amount of brown fused alumina grit rough grinding, cheap, can be widely used.

(cheap brown fused alumina factory south korea)The hardness of pink corundum is slightly higher than that of brown corundum, and the toughness is lower than that of brown corundum. During grinding, the abrasive grains are easily broken. Therefore, the grinding heat is small, and it is suitable for manufacturing fine-finished hardened steel, high-carbon steel, high-speed steel, and abrasive. Grinding wheels for thin-walled parts cost more than brown corundum.

Green silicon carbide has higher hardness and brittleness than black silicon carbide, sharp abrasive particles, and good thermal conductivity. It is suitable for grinding hard and brittle materials such as cemented carbide, optical glass, and ceramics. Chrome corundum grinding wheels are suitable for white aluminum oxide 120 grit  grinding workpieces with high surface processing quality such as cutting tools, measuring tools, instruments and threads.

(cheap brown fused alumina factory south korea)brown aluminum oxide 70 grit grinding wheels are suitable for grinding tough and hard materials such as stainless steel and high vanadium high speed steel and workpieces that are easily deformed and burned. Microcrystalline corundum grinding wheel is suitable for grinding stainless steel, bearing steel and special nodular cast iron. It is used for black silicon carbide suppliers forming grinding, plunging grinding and mirror grinding. 

white fused aluminum oxide 60 grit grinding wheels are suitable for grinding austenitic stainless steel, titanium alloy, heat-resistant alloy, and especially suitable for heavy-duty grinding. When grinding with a coarse-grained grinding wheel, the production efficiency is high, but the surface of the workpiece is rough; when aluminium oxide grit 24 mesh grinding with a fine-grained grinding wheel, the surface roughness of the workpiece is better, and the productivity is lower.(cheap brown fused alumina factory south korea)
