3M™ Cubitron™ ll Cloth Belt 784F, 80+ YF-weight, 65 in x 110 in, Sine-lok Precision Roll Grinding, Full-flex, 2 ea/Case

The 3M™ Cubitron™ II Cloth Belt 784F is expertly engineered to deliver exceptional results in medium pressure industrial applications. At the heart of this belt is the innovative 3M Precision-Shaped Grain, a breakthrough abrasive technology that enables the belt to cut with remarkable speed and efficiency. This unique grain is designed to self-sharpen during use, ensuring consistent performance throughout the grinding process. The belt features a blend of ceramic and aluminum oxide minerals, providing a cost-effective solution for medium-pressure tasks where a full ceramic belt may not be necessary. For optimal flexibility and durability, coarse grades (36-80) utilize a robust YF-weight backing, while finer grades (120-180) are constructed with a lighter XF-weight backing. Both backings are moderately flexible, allowing the belt to conform to slight contours and flat surfaces with ease.

In demanding environments such as robotic grinding and degating, the 3M Cubitron II Cloth Belt 784F stands out as a premium choice. Its fast-cutting, long-lasting abrasive properties are particularly advantageous in automated systems, where minimizing downtime and maximizing productivity are critical. The precision-shaped mineral continually fractures into sharp, fresh cutting edges, maintaining high performance and reducing the need for frequent belt changes. This efficiency translates into more parts produced per belt, optimizing the throughput of robotic cells and enhancing overall operational efficiency.

Designed with a water-resistant polyester backing, the 3M Cubitron II Cloth Belt 784F offers the flexibility to be used in both wet and dry grinding applications. This versatility is especially important when working with heat-sensitive alloys such as stainless steel, titanium, nickel, and cobalt alloys. To further protect these materials from heat-induced stress cracks and discoloration, the belt incorporates a specialized grinding aid that helps lower grinding temperatures. The abrasive is securely bonded to the backing with a durable resin, ensuring reliable performance even under high heat and pressure conditions.

3M Precision-Shaped Grain represents a significant advancement in abrasive technology. Developed through a proprietary process, this ceramic mineral is engineered for enhanced toughness and hardness. The grains are precisely shaped into uniform triangles, which continually fracture to reveal new, ultra-sharp points and edges. Unlike conventional abrasives that tend to gouge or plow through materials, these grains slice cleanly through substrates, resulting in a faster cut and reduced heat buildup. This not only minimizes the risk of heat-related damage to the workpiece but also extends the life of the belt, making it a superior choice for demanding grinding applications.

With over a century of expertise in abrasive solutions, 3M is a trusted partner for the metalworking industry. The 3M Cubitron II Cloth Belt 784F exemplifies this legacy, offering a combination of advanced minerals, durable backings, and robust bonds to meet a wide range of grinding and finishing needs. The belt’s exceptionally fast cutting action and long service life make it ideal for industrial environments where consistent, high-quality results are essential. Whether working with standard metals or heat-sensitive alloys, you can rely on the 3M Cubitron II Cloth Belt 784F to deliver immediate, uniform results throughout its lifespan.
