Designed for Industrial Environments
The exceptionally fast cut and long life of ceramic grain make this belt ideal for industrial environments. It is also heat resistant, produces a uniform finish over the life of the product, and helps eliminate burning during end-grain sanding applications. The YF-weight cloth backing on the 3M Cubitron II Cloth Belt 984F provides durability, and the mineral is resin bonded to the backing for reliable performance ? even under high heat and pressure.
Ideal for Robotic Grinding and Degating
In medium and high-pressure applications like robotic grinding, it’s important to choose a premium abrasive belt like the fast-cutting, long-lasting 3M Cubitron II Cloth Belt 984F. The mineral in this belt continually fractures into sharp edges to keep cutting through the life of the belt, reducing changeouts and downtime in robotic cells. This helps maximize the efficiency of the cell, allowing you to produce more parts per belt.
A Leader in High-Performing Abrasives
Our proprietary 3M Cubitron II products have raised the bar for high-performing abrasives. Our engineers started with 3M Ceramic Abrasive Grain and used technology to electrostatically orient each triangular structure on the backing to form sharp peaks and maximize cutting potential. These peaks act like individual cutting tools that slice through metal, and continuously shelf-sharpen as the points break off, ensuring extended high performance in heavy-duty production applications. The grains wear evenly and provide extra-long life and consistency with less grinding pressure. The result is that Cubitron II products outcut and outlast every conventional ceramic industrial abrasive product on the market, maximizing productivity and minimizing belt stress.
Belts come with various splices that join the belt ends. 3M Cubitron II Cloth Belt 984F has a fabric splice for added strength when grinding in medium to high pressure applications.
