Oem 60 Grit Flap Disc Calcined Bladed Polishing Wheel 100mm Size Polished Rust

An abrasive flap disk, also known as a sanding flap disk, is a type of abrasive tool widely used in grinding, polishing, and surface finishing operations. It consists of multiple overlapping abrasive flaps that are assembled onto a central backing plate.

Structure

1. Abrasive Flaps
   These are the key components of the flap disk. They are usually made of abrasive materials such as aluminum oxide, zirconia alumina, or silicon carbide. The flaps are cut into specific shapes and sizes. Each flap has an abrasive surface that contacts the workpiece during operation. The abrasive grains on the flaps are bonded using resin or other suitable bonding agents.
2. Backing Plate
   The backing plate provides support for the abrasive flaps. It is usually made of a durable material like plastic or metal. The center of the backing plate has a hole for mounting the disk onto a grinding machine's spindle. The design of the backing plate ensures that the flaps are held firmly in place during high - speed rotation.
3. Attachment Mechanism
   There are various ways to attach the abrasive flaps to the backing plate. Commonly, they are either glued or mechanically fastened. Some flap disks use a combination of both methods to ensure the stability of the flaps during operation.

Feature of flap disk

The cutting force is very strong, the synchronous consumption effect of heat and wear resistance/sand and cloth is very significant, and the service life is 3-4 times longer than that of the same industry products.

Characteristics

1. Versatility
   Flap disks can be used on a wide variety of materials including metals, woods, plastics, and composites. Their ability to handle different materials and surface conditions makes them a very popular choice in many industries.
2. Efficient Grinding and Polishing
   The multiple overlapping flaps provide a continuous cutting action. As the disk rotates, new abrasive surfaces are constantly exposed, ensuring consistent grinding performance. This design also allows for better heat dissipation compared to some other abrasive tools, reducing the risk of overheating the workpiece.
3. Long Lifespan
   Due to the design of the abrasive flaps and their attachment method, flap disks have a relatively long lifespan. The flaps can wear down gradually during use, and the remaining flaps can still continue to provide effective grinding until the disk is completely worn out.
4. Good Surface Finish
   Flap disks can produce a relatively smooth surface finish. Depending on the type of abrasive and the grit size used, they can achieve different levels of smoothness, from rough grinding to fine polishing. This makes them suitable for applications where a high - quality surface finish is required.

Usage Tips:

• Always match the flap disk to the material being worked on.
• Use the appropriate speed and pressure to maximize effectiveness and minimize wear.
• Regularly inspect the disk for wear and replace it as needed to ensure safety and performance.

Flap disks are a valuable tool for both professionals and DIY enthusiasts, offering a balance of speed and finish quality in various applications.
