Cubitron™ ll Cloth Belt 784F

The 3M™ Cubitron II cloth belt 784F was engineered with medium pressure industrial applications in mind. Using 3M precision-shaped grain, which cuts exceptionally fast and self-sharpens during grinding, this high-performing belt contains a ceramic and aluminum oxide blend that delivers cost-effective performance on medium-pressure applications where a full ceramic belt may be underutilized.

Coarse grades 36-80 have a YF-weight backing, while finer grades of 120-180 have a lighter XF-weight backing. Both weights are moderately flexible and conform well to slight contours and flat surfaces.

In medium and high-pressure applications like robotic grinding, it is important to choose a premium abrasive belt like the fast-cutting, long-lasting 784F. The mineral in the belt continually fractures into sharp edges to keep cutting throughout the life of the belt, reducing change-outs and downtime in robotic cells. This helps maximize the efficiency of the cell, allowing users to produce more parts per belt.

The 784F has a water-resistant polyester backing, so it may be run wet or dry. To protect heat-sensitive alloys such as stainless steel, titanium, nickel alloys, and cobalt alloys from heat-related stress cracks and discoloration, 3M incorporated a grinding aid to help reduce grinding temperatures. Additionally, the abrasive is firmly bonded to the backing with resin to maintain durability under high heat and pressure..

The 3M precision-shaped grain is a major advancement in abrasive technology. This ceramic mineral is designed using a proprietary process to enhance the toughness and hardness of the grain. 3M scientists then went one step further and engineered the mineral to form uniform triangular shaped grains that continually fracture into super-sharp points and edges that slice through the substrate, rather than gouging or plowing like conventional abrasives. It creates a super-fast cut and lessens heat build-up on the workpiece, reducing heat-related stress cracks and discoloration. Because precision-shaped grain stays cooler and sharper, it lasts longer than conventional abrasives.
