The brown fused alumina flap wheel with a handle, also known as a shank-mounted abrasive cloth wheel or flap wheel grinding head, is a type of abrasive cloth wheel. The following are its details:
- Abrasive: Brown fused alumina is used as the abrasive grains. Brown fused alumina has the characteristics of high hardness, good toughness, strong wear resistance, and excellent self-sharpening property. It can effectively carry out grinding operations and continuously generate new sharp cutting edges during the grinding process, maintaining good grinding performance.
- Base Material: Usually, a cloth base is used as the base material, which is made into abrasive cloth through an assembly line. The cloth base has high tensile strength and can withstand the pressure and impact force during the grinding process, ensuring the stability and durability of the abrasive cloth wheel.
- Connection Part: It is bonded with resin and composed of scale-like abrasive cloth suspended on a steel flexible shaft. The steel flexible shaft provides good support and rotational flexibility, enabling the flap wheel to be conveniently installed on various grinding equipment for operation.
- Shape: Common shapes include cylindrical and bullet-shaped.
- Size: The diameter generally ranges from 15mm to 80mm, the thickness is usually 25mm, and the common diameter of the handle is 6mm.
- Grit: Conventional grit numbers include 60#, 80#, 120#, etc. Coarse grits such as 60# are suitable for quickly removing materials and rough machining, while fine grits such as 120# are used for semi-finishing and finishing to obtain a higher surface finish.
- Strong Grinding Force: Due to the high hardness and sharpness of the brown fused alumina abrasive, the flap wheel with a handle has a powerful grinding ability. It can quickly and effectively grind the surface of the workpiece, easily removing burrs, oxide scales, weld seams, etc.
- Long Service Life: The high tensile strength of the cloth base, combined with the firm bonding of the resin, makes the abrasive cloth not easy to fall off. Coupled with the wear resistance of the brown fused alumina, it jointly ensures that the flap wheel has a long service life, reduces the replacement frequency, and improves work efficiency.
- Simple Assembly: The design with a handle enables it to be conveniently installed on various grinding equipment, such as electric grinders and angle grinders. The operation is simple and quick, reducing labor intensity.
- Smooth Operation: The product undergoes strict balancing treatment during the manufacturing process to ensure smooth operation at high speeds, reducing vibration and noise. This not only improves the processing quality but also provides a good working environment for operators.
- Metal Processing: It is widely used in industries such as aerospace, marine shipbuilding, automobile manufacturing, and hardware production. It can perform polishing and finishing on various complex surfaces and deep holes of metal products. For example, it can grind and polish concave and convex surfaces and side surfaces, and it can also be used for grinding weld seams, removing burrs, and rust removal.
- Non-metal Processing: It is suitable for the surface treatment of non-metal materials such as plastics, bamboo, and wood. It can perform processing such as grinding and polishing to improve the surface quality and increase the smoothness.
- Proper Installation: Ensure that the flap wheel with a handle is correctly installed on the grinding equipment and firmly fixed to prevent loosening or falling off during use, which may cause safety accidents.
- Select Appropriate Parameters: According to the material, hardness, and processing requirements of the workpiece, reasonably select parameters such as grinding speed, feed rate, and grinding pressure to avoid poor surface quality of the workpiece or excessive wear of the flap wheel due to improper parameter selection.
- Safety Protection: Operators should wear personal protective equipment such as safety goggles, masks, and gloves during use to prevent debris and dust generated during the grinding process from causing harm to the body.
- Storage Conditions: Store the brown fused alumina flap wheel with a handle in a dry and ventilated environment, avoiding moisture, rain, and direct sunlight to prevent the performance degradation and shortened service life of the abrasive cloth wheel.
