The fan-shaped blades are primarily formed by cutting sandpaper into uniform segments, bonding them to a base substrate with adhesive, and curing at high temperatures. When used with an angle grinder, they are ideal for grinding and finishing weld seams and burrs on edges. They can be interchangeable with cup-shaped grinding wheels. Offering excellent elasticity, high efficiency, superior heat dissipation, and low noise levels, they can replace resin cup wheels. Featuring strong elasticity, high tensile and flexural strength, self-sharpening properties, high grinding rates, and low noise, they are ideal for grinding weld seams inside enclosures and deburring stamped parts.

Selection of Abrasive Blade Material:
Numerous raw materials are available for manufacturing abrasive blades, including zirconia alumina, nylon abrasive belts, silicon carbide, brown fused alumina, calcined alumina, and ceramics. However, brown fused alumina remains the most widely used material today.
Brown fused alumina boasts high purity, excellent crystallization, strong fluidity, low linear expansion coefficient, and corrosion resistance. Practical verification by multiple enterprises confirms that brown fused alumina exhibits no blasting, powdering, or cracking during application. Particularly, its significantly higher performance relative to other traditional abrasives and favorable cost-effectiveness make it an outstanding choice for louver blade raw materials.

Primary Applications of Abrasive Discs:
Suitable for grinding and polishing stainless steel, metals, metallurgical products, automotive components, wood, marble, and similar materials. Zirconia alumina (ZA) is particularly well-suited for stainless steel processing. It can replace resin-bonded grinding wheels, offering superior elasticity, high tensile and flexural strength, excellent self-sharpening properties, high grinding rates, and low noise levels. It is ideal for grinding weld seams inside enclosures and removing stamping burrs.
