Products Description
Aluminium oxide sanding belt is a multifunctional industrial material made of high-purity aluminium oxide powder mixed with additives. Its manufacturing process includes multiple steps such as mixing, pressing and sintering. It is suitable for many fields such as metal processing, woodworking, ceramic processing, etc.
Product Specification
Product Features
Good Waterproofness
The surface of the aluminum oxide sanding belt is coated with a special fluorocarbon resin coating, which has low surface energy, a water contact angle greater than 110°, and it is difficult for water to adhere and penetrate.
High Grinding Strength
The aluminum oxide sanding belt is a multi-layer composite structure. The outer layer is a working layer with abrasives, the middle layer is a fiber-reinforced layer to disperse the grinding force; the inner layer is a rubber backing layer to buffer the impact force. This structure enables the sanding belt to withstand a grinding pressure of 60N/cm². During high-load grinding, each layer works together and the abrasive evenly shares the force.
Wide Range Of Applications
The aluminum oxide sanding belt can grind a variety of metal materials, such as steel, aluminum alloy, copper alloy, etc., and can also perform surface treatment on some non-metallic materials, such as ceramics and glass.
Product Application
Metal Processing Field
Aluminum oxide sanding belt is mainly used for grinding, polishing and deburring of metal surfaces. Its function is to remove the oxide layer, flaws and uneven parts of the metal surface through the friction between the aluminum oxide abrasive on the surface of the sanding belt and the metal surface, and eliminate the burrs on the edge of the parts.
Wood Processing Industry
In the wood processing industry, the aluminum oxide sanding belt is responsible for the flattening, roughness adjustment and pre-treatment of the wood surface before painting. It can smooth the uneven parts such as bumps and burrs on the wood surface, adjust the roughness of the wood surface by controlling the particle size and grinding process of the sanding belt, and facilitate the subsequent painting and finishing processes.
Stone Processing Field
Aluminum oxide sanding belt is mainly responsible for grinding and polishing the stone surface in stone processing. The sanding belt can effectively remove the cutting marks, stains and unevenness on the stone surface, so that the stone surface can achieve the required gloss and smoothness.

【Frequently Asked Questions】
Q: What is an aluminium oxide sanding belt?
An aluminium oxide sanding belt is a belt-shaped grinding tool made of aluminium oxide abrasive as the main grinding medium, attached to a flexible substrate (such as cloth, paper, etc.).
Q: How does an aluminium oxide sanding belt work?
The working principle of an aluminium oxide sanding belt is based on friction and cutting. When the belt is driven by a drive device and rotates at high speed, the aluminium oxide abrasive particles come into contact with the surface of the workpiece. With their own hardness and sharpness, they cut into the surface of the material and remove excess material, thereby achieving grinding, polishing and other processing effects on the surface of the workpiece.
Q: What are the applications of aluminium oxide sanding belts in the metalworking industry?
In metalworking, aluminium oxide sanding belts can be used for grinding external circles, planes, internal holes, etc., such as external cylindrical grinding of shaft parts and surface grinding of steel plates; they can also be used for edge processing such as deburring and chamfering; they can also polish metal surfaces.
Q: What role does an aluminium oxide sanding belt play in the woodworking industry?
In wood processing, the aluminum oxide sanding belt can grind the wood surface to make the thickness of the board uniform; it can remove burrs, scars and other defects on the wood surface and improve the surface flatness; it can also finely grind the wood by combining sanding belts of different grain sizes to prepare for subsequent painting, veneer and other processes.
Q: What preparations need to be made before using the aluminum oxide sanding belt?
First, check whether the model and specifications of the aluminum oxide sanding belt match the processing requirements, and confirm that the appearance of the sanding belt is not damaged or debonded. Then install the sanding belt, adjust the tension of the sanding belt to the appropriate state, and check the operation of the driving equipment to ensure that it can drive the sanding belt normally.
Q: How to correctly install the aluminum oxide sanding belt?
Put the aluminum oxide sanding belt on the drive wheel and the tensioning wheel, and pay attention to the correct winding direction of the sanding belt to avoid twisting. Adjust the tensioning wheel to make the sanding belt tension moderate. Too loose will cause the sanding belt to slip and affect the grinding effect; too tight will shorten the life of the sanding belt and even cause the sanding belt to break.
Q: What safety precautions should be taken when using an aluminum oxide sanding belt?
Operators need to wear protective glasses, gloves and other protective equipment to prevent debris generated during grinding from splashing and injuring people. Make sure the workpiece is firmly fixed to avoid danger caused by the movement of the workpiece during grinding. At the same time, pay attention to the running direction of the aluminum oxide sanding belt, and do not perform cleaning operations while the belt is running.
Q: How to judge whether the aluminum oxide sanding belt needs to be replaced?
When the grinding efficiency of the aluminum oxide sanding belt is significantly reduced, it is difficult to achieve the expected processing effect even if the pressure is increased; or there are obvious scratches, burns and other defects on the surface of the workpiece; and when the belt is severely worn locally and the abrasive falls off, it means that the belt has failed and needs to be replaced in time.
Q: How to perform daily maintenance on the aluminum oxide sanding belt?
After use, the debris and dust on the aluminum oxide sanding belt should be cleaned in time to prevent its accumulation from affecting the performance of the belt. Store the belt in a dry and ventilated environment to avoid moisture and heat deformation.
