Polishing and Grinding Discs

Flap Sanding Disc for Polishing and Grinding

The performance of the Keying Polishing and Grinding Disc with it's diffirent shapes that arranged by the abrasive cloth grinding flaps, is widely known as the fast grinding, finishing and blending application purpose of abrasive products.  It is able to have higher laods performance than normal sanding paper sheet or coated abrasive belt. It provides stability during operation with cooler cut 2 or 2.5 times faster than the cutting rate of a belt), less vibration and smoother finish without gouging. Polishing and Grinding Discs are good choose to stock removal through blending applications in a single action.

Are Flap Discs Good For Removing Rust?

Are Flap Discs Good For Removing Rust?

Flap discs, especially non-woven discs, are ideal tools for removing paint and rust. Non-woven flap discs, or the ones with aluminum oxide, can be used for paint or rust removal applications.

Abrasive Disc Uses

Flap Disc

Flap discs initially become one of the top sellers in metal treatment markets, especially in applications of welding, deburring, rust, and scratch removing and snagging. This abrasive tool is suitable for a wide range of ferrous and non-ferrous metals:

Flap Disc Polishing for Steel and Stainless Steel: Buffing flap discs have a good stock removal rate on steel and stainless steel, there is a wide range of grain types that can be chosen by considering the cutting sharp rate, finishing looks, service life, etc.

Abrasive Flap Discs For Other Metal Material

Polishing Flap Discs for other metal materials: Compared to other metals, aluminum has characterizations of a lower melting point and is a softer metal with relatively a low density. Therefore, aluminum material needs abrasives to have more synchronous consumption and self-sharpening affections during grinding.

Type27 And Type 29

Type27: If operators need to surface-clean or provide a smooth finish, use a T27 flat disc that's parallel to your work area, you will have a little bit more force when flap discs are touching the surface. For best results, use light and even pressure to optimize the grinding process and reduce loading.

Type 29: Operators may want to try  T29 conical disc at a 15 to 20-degree angle to provide maximum and full coverage when it's deep on the weld of the surface.

Abrasive Flap Discs For Wood

When it comes to wood sanding, flap sanding discs are excellent tools. For wood applications, consider using abrasive flap discs with aluminum oxide abrasives and non-woven materials. Start with a heavy grit for removing imperfections, then gradually move to finer grits for a smooth and shining surface finish. Recommended grit sizes for wood sanding are 120, 150, 180, and 240 for rust removal, welding, grinding, blending, and polishing. For pre-painting preparation, commonly use 320#, 400#, and 600# grit sizes. Achieve a flawless result with these flap sanding discs for wood.

Abrasive Flap Discs For Paint Removal

Abrasive Flap Discs for paint removal: Paint removal for metal parts, stripper remover discs, and fiber discs, are also ideal tools for removing paint and rust. These discs can grind and finish in a single operation while offering fast and efficient stock removal.

Grit and Application Guide Of Flap Discs


Flap Discs VS Grinding Wheels VS Fibre Discs
The Grinding Wheel Has High Adaptability

Grinding Wheels are highly adaptable and suitable for a whole flat surface of metal fabrication applications. Grinding wheels with features of rapid stock removal and simple proceeding grinding, especially the surface finish requirement is not the most important concern and there are no multiple steps required to be involved in the fabrication. 

Flap Discs Usually Have The Following Key Advantages VS Grinding Wheel

Flap discs generally have the following key advantages over grinding wheels, even though both of them are great for grinding applications:

1. More accurate grind

2. Faster and easier stock removal

3. Fine and smoother finish, and step-by-step processing

4. Fewer vibrations and better radiating

5. Easier control and equipment

Flap Discs Vs Grinding Wheels

Flap Discs Usually Have The Following Key Advantages VS Standard Fibre Discs

Flap discs generally have the following key advantages by comparing with standard Fibre Discs

1. Longer lifetime and efficient grinding

2. Reduce action waste to save labour costs

3.  More consistent finish

4. Easier storage and longer service life
