Flap wheel and grinding disc are two different industrial consumable products, which have obvious differences in structure, use and characteristics.
Flap wheel is a strong elastic grinding disc, mainly composed of plastic or fiber mesh cover bonded with sandpaper sheets. Its impeller base material is diverse, including mesh, nylon, plastic, steel paper, etc., with different numbers of sheets, evenly distributed in a fan shape. The particle size range of flap wheel is between 36#-400#, the most common ones are 60# and 80#, and the outer diameter is usually 4"-7". It is mainly used to be installed on angle grinders, suitable for grinding welds and positive edge burrs, and can replace resin cymbal grinding wheels. The characteristics of flap wheel include good elasticity, high efficiency, good heat dissipation, low noise, strong elasticity and tensile and bending strength, good self-sharpening, high grinding rate, low noise, especially suitable for grinding welds in boxes and flash of stamping parts. Widely used for grinding and polishing of various stainless steel and carbon steel structural parts.
Grinding sheet is a product that uses high-voltage electrostatic field force to implant fine abrasive particles (such as aluminum oxide or silicon carbide) on high-strength polyester film, so that all the sand particles are pointed outward, cutting is sharp, and can provide higher grinding efficiency and bright and delicate polishing effect. Grinding sheet is made by backing velvet and cutting, and is mainly used to provide higher grinding efficiency and bright and delicate polishing effect.
In summary, although both flap wheels and grinding sheets are used for industrial grinding and polishing, they have their own characteristics in structure, material, use and characteristics. Flap wheels focus more on their elasticity and suitability for specific industrial applications, such as the processing of welds and stampings, while grinding sheets emphasize their high grinding efficiency and bright and delicate polishing effect.
