Sand disc, also known as elastic grinding disc, flap discs, it is made by a lot of abrasive sheet. firmly bonded to the fiber backing/plastic backing or metal backing plate matrix on a disc coated abrasive tool. The minimum diameter of common flap disc is 100mm, and the maximum can be up to 180mm.
Flap disc has the following obvious advantages and characteristics
1. With elastic structure, it can polish plane/surface/groove/corner, etc., especially suitable for welding seam grinding and derusting of thinner workpiece.
2. Self-sharpening and high efficiency. In the process of grinding abrasive cloth sheet synchronous consumption, constantly leakage of new grain, to ensure that the grinding process is always sharp, high efficiency.
3. Good heat dissipation, not easy to damage the workpiece, avoid deformation and discoloration caused by overheating in the processing process of the workpiece
4. Light weight, good safety and low noise. In the process of operation, even if there is flaps drop off, the damage to the personnel and the equipment is small.
5. Strong flexibility and variety. According to the workpiece requirements of grinding and polishing, no matter point or surface, line or arc, there are suitable products to choose from.
Therefore, the flap disc is widely used in the automobile/bicycle/automobile manufacturing/glass products/stainless steel products/metal products /furniture /pressure vessels and other industries in the weld/welding spot/burr and flash polishing/rust/metal surface defect polishing and fine polishing. Compared with the resin sand wheel, it has better elasticity, and has strong load grinding performance compared with the fiber disc. They are also installed in the portable Angle grinder, with good performance and widely application.
