FIVE INCH ALUMINUM OXIDE SANDING DISC

Material Properties

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

Flocking Backing: The backing is flocked on the back, usually using soft velvet as the backing material. This flocked backing has good flexibility and adhesion. On the one hand, it can be tightly bonded with the grinding tool to ensure that the grinding sheet will not easily fall off during operation, improving operational safety. On the other hand, the soft backing can absorb some of the impact force during grinding to reduce damage to the surface of the material being ground, and also allows the grinding sheet to better adapt to the grinding needs of different shapes and contours.

Product Specifications

Various Sizes: Common sizes include 1 inch (25mm), 2 inches (50mm), 3 inches (75mm), 4 inches (100mm), 5 inches (125mm), 6 inches (150mm), and 7 inches (180mm), which can meet the needs of different grinding scenarios and tools.

Rich Grain Sizes: The grain size range is relatively wide, from coarse grain sizes such as 80# and 120# used for quick material removal and rough grinding processes to fine grain sizes such as 1000# and 1500# or even higher grit numbers used for fine polishing and surface finishing. The appropriate grain size can be selected according to the specific grinding requirements.

Application Fields

Metal Processing: It can be used for deburring, rust removal, and polishing of metal products. For example, in the production process of stainless steel cutlery, tableware, and thermal flasks, it can effectively remove burrs produced during processing to make the edges smooth. It can also remove rust stains on metal surfaces to restore the metal luster and provide a good foundation for subsequent electroplating, spray painting, etc.

Wood Processing:It is suitable for rough grinding, leveling, and removing stains on wood. In furniture manufacturing, it can be used to rough grind wood boards to make the surface flat, which can prepare for subsequent assembly and assembly processes; it can also be used for fine grinding on furniture that has been assembled to reveal the wood grain and texture and enhance the aesthetics of the furniture.

Automotive repair and beauty: In automotive repair, it can be used for car paint repair, grinding scratches and wear on the car paint surface to make the repaired surface smooth; it can also be used for grinding wheels, removing dirt, oxidation layer and minor scratches on the wheel surface to restore the wheel luster. In the field of automotive beauty, it can be used for polishing plastic and leather parts in the interior of cars to enhance the overall texture of the interior.

Electronics and precision instrument manufacturing: In the production of electronic circuit boards, it can precisely control the grinding force and accuracy to remove excess copper foil, solder and impurities on the circuit board surface to ensure the electrical performance and surface flatness of the circuit board. For small parts in precision instruments, such as watch parts and optical lenses, it can perform ultra-fine grinding to meet their high precision size and surface quality requirements.

Product advantages

Sharp cutting: The sand grains are carefully selected and the sand is planted with an electrostatic method, so that the sharp edge of the sand grains is facing outward, sharp cutting, even planting of sand, and better grinding effect than other products, and less uneven sand marks.

Less clogging: There is usually an anti-clogging coating on the surface to enhance the adhesion of the mineral sand and prevent sand particles from clogging, reducing the decrease in grinding efficiency and the frequency of sandpaper replacement, and prolonging the service life of the sandpaper.

Convenient to use: The back velvet design makes it easy to install and remove, and it can be used with a hook-and-loop tray for easy replacement, which improves grinding efficiency.

Durable: The aluminum oxide abrasive itself has high wear resistance, couple
