FIVE INCH ALUMINUM OXIDE FLAP DISC

Material and Structure

Abrasive: Aluminum oxide is used as the abrasive, which has high hardness, strong wear resistance, and good chemical stability. It can maintain good cutting performance during grinding and effectively remove defects and burrs on the surface of various materials.

Base and Adhesive: High-strength fiber or paper is usually used as the base, which has certain flexibility and tensile strength. The aluminum oxide abrasive is firmly bonded to the base with a special adhesive, ensuring that the abrasive does not easily fall off during high-speed grinding, which guarantees the stability and safety of grinding.

Product Specifications

Dimensional Specifications: Common outer diameters include 4 inches (100mm), 5 inches (125mm), 6 inches (150mm), and 7 inches (180mm), and the hole diameter is usually 16mm or 22mm. Users can choose the appropriate size according to their actual grinding needs and the tools used.

Grain Size Specifications: The grain size range is relatively wide, from coarse grain sizes such as 40#, 60#, 80# for quick material removal and rough grinding processes to fine grain sizes such as 240#, 320#, even higher grit numbers for fine polishing and surface finishing. The appropriate grain size can be selected according to needs.

Performance Features

Strong Cutting Ability: The high hardness of aluminum oxide abrasive makes it have excellent cutting ability, which can quickly remove material surface stock and improve grinding efficiency.

Good self-sharpening: In the grinding process, the abrasive particles will gradually wear and become dull, but the abrasive of the alumina blade has good self-sharpening, that is, with wear, the new sharp abrasive particles will be constantly exposed, maintain continuous cutting ability, and reduce the frequency of replacement of the grinding disc.

Good heat dissipation: high speed grinding will produce a lot of heat, the product can dissipate the heat in time to avoid the problem of premature abrasive failure, workpiece deformation or burn caused by overheating, which is conducive to improving the grinding quality and extending the service life of the grinding disc.

High safety: The use of high-quality binder and matrix materials to ensure that the combination of abrasive and matrix is firm, in the use of the process is not easy to break, splash and other dangerous situations, while the product meets the relevant safety standards, safe and reliable use.

Scope of application

Metal processing: widely used in grinding of various metal materials, such as ordinary carbon steel, hard bronze, alloy steel, malleable cast iron, quenched steel, etc., can deburring, rust removal, weld grinding, surface polishing and other processing of metal products.

Non-metallic processing: wood, plastic, rubber, stone and other non-metallic materials also have a good grinding effect, can be used for wood surface dressing, plastic rubber products removal and surface polishing, stone cutting surface grinding and defect repair.
