Solving the Challenges of Soft Metals

3M Cubitron II Cloth Belt 981F is specifically designed to address three common issues encountered when grinding and finishing soft metals such as aluminum. These problems include abrasive loading, edge-shelling, and operator fatigue.

To combat abrasive loading, a dry lubricant is integrated into the abrasive material. This allows the abrasive grain to remain free from metal coating, ensuring that the cutting surface of the mineral remains effective. Additionally, the waterproof backing of the belt enables the user to rinse both the workpiece and the cloth during use, in case the abrasive starts to clog.

To prevent edge-shelling, 3M Cubitron II Cloth Belt 981F features a durable Y-weight polyester cloth backing. This backing is specifically designed to withstand the stresses associated with working on gates, parting lines, and flashing in tight spaces. Unlike other cloth grinding belts, this belt also incorporates a proprietary resin system that enhances mineral adhesion, further reducing the chances of shelling.

Worker fatigue can be a concern when grinding softer substrates. However, 3M Cubitron II Cloth Belt 981F is designed to grind efficiently, and its use of 3M Precision-Shaped Grain allows the operator to cut with less pressure. This can help to reduce physical exertion and minimize operator fatigue.

About 3M Precision-Shaped Grain

3M Precision-Shaped Grain is the advanced technology that powers 3M Cubitron II products. This unique grain structure consists of sharp, triangular structures that continually fracture into sharp points and edges. Unlike traditional abrasives that tend to gouge or plow, this precision-shaped grain slices cleanly through the substrate. This results in a fast cut and reduces heat build-up in the workpiece, minimizing heat-related defects. Additionally, the abrasive itself stays cooler and sharper, leading to a longer lifespan compared to conventional abrasive belts. This reduces the frequency of belt changeovers and lowers operational costs. The closed coat construction of the belt ensures a dense spread of abrasive grains across the cloth surface, enabling fast cutting and providing a consistent finish.
