3M Cubitron II Cloth Belt 784F features 3M Precision-Shaped Grain for longer life and a faster, more consistent cut than conventional ceramic aluminum oxide belts. A precise mix of shaped ceramic and premium aluminum oxide delivers optimal cut in medium-pressure grinding and blending applications. The belt also features a waterproof backing and grinding aid.

  • 3M Precision-Shaped Grain blend provides significantly longer life than comparable aluminum oxide belts
  • Proprietary mineral provides consistent, faster results on medium pressure applications, helping to improve productivity and throughput
  • Reduces changeouts and downtime in robotic and pressure-assisted applications
  • Moderately flexible backing provides conformability for grinding and blending both straight and contoured surfaces
  • YF-weight polyester backing is used for Grades 36-80, while lighter XF-weight polyester backing is used for Grades 120-180
  • Grinding aid cools abrasive processes on heat-sensitive alloys

PRODUCT FAQ

  1. Certainly! Feel free to ask any questions.

    What makes the 3M™ Cubitron™ ll Cloth Belt 784F unique?

  2. The 3M™ Cubitron™ ll Cloth Belt 784F stands out for its exceptional durability and cutting efficiency compared to traditional abrasive belts.

    What does "120+ XF-weight" mean in the product description?

  3. The "120+" refers to the grit size of the belt, indicating a medium level of coarseness, while "XF-weight" signifies an extra-fine weight backing ideal for heavy-duty applications.

    How does the Fabri-lok feature enhance the performance of this belt?

  4. The Fabri-lok feature ensures secure attachment and smooth operation on compatible power tools, preventing slipping or damage during use.

    Can you explain what is meant by "Single-flex" in this belt's specifications?

  5. "Single-flex" indicates that this belt is designed for flexibility in one direction only, making it suitable for specific types of grinding and finishing tasks.

Outstanding Performance on Medium Pressure Applications

The 3M Cubitron II Cloth Belt 784F is specifically designed for medium pressure industrial applications. It features 3M Precision-Shaped Grain technology, which allows for exceptional cutting speed and self-sharpening during grinding. This belt is made with a blend of ceramic and aluminum oxide, providing cost-effective performance on medium-pressure applications where a full ceramic belt may not be necessary.

The belt is available in coarse grades 36-80, which have a YF-weight backing, and finer grades 120-180, which have a lighter XF-weight backing. Both backing weights offer moderate flexibility and conform well to slight contours and flat surfaces.

Ideal for Robotic Grinding and Degating

In medium and high-pressure applications such as robotic grinding, it is crucial to choose a premium abrasive belt like the 3M Cubitron II Cloth Belt 784F. This belt is known for its fast-cutting and long-lasting performance. The mineral in the belt continuously fractures into sharp edges, ensuring consistent cutting throughout the belt's lifespan. This reduces the need for frequent belt changes and minimizes downtime in robotic cells, maximizing efficiency and allowing for increased production.

Run it Wet or Dry

The 3M Cubitron II Cloth Belt 784F is designed to be used wet or dry. Its water-resistant polyester backing allows for wet grinding, while also providing protection for heat-sensitive alloys such as stainless steel, titanium, nickel alloys, and cobalt alloys. The belt incorporates a grinding aid to help reduce grinding temperatures, preventing heat-related stress cracks and discoloration. Additionally, the abrasive is firmly bonded to the backing with resin, ensuring durability even under high heat and pressure.

The Science of 3M Precision-Shaped Grain Blend

3M Precision-Shaped Grain is a revolutionary abrasive technology developed by 3M. This ceramic mineral is created using a proprietary process that enhances its toughness and hardness. The mineral is then engineered to form uniform triangular-shaped grains that continually fracture into super-sharp points and edges. Unlike conventional abrasives that tend to gouge or "plow," 3M Precision-Shaped Grain slices through the substrate, resulting in a super-fast cut and reduced heat build-up on the workpiece. This helps prevent heat-related stress cracks and discoloration. Furthermore, the cooler and sharper nature of 3M Precision-Shaped Grain ensures its longevity, outlasting conventional abrasives.

Engineered for Demanding Industrial Environments

For over a century, 3M has been a trusted supplier of abrasives to the metalworking industry. With a wide range of minerals, backings, and bonds, 3M offers a comprehensive selection of quality coated and bonded abrasives for various grinding and finishing applications. The exceptional cutting speed and long life of 3M Precision-Shaped Grain make it particularly suitable for demanding industrial environments. Trust the 3M Cubitron II Cloth Belt 784F to deliver consistent and uniform results throughout its lifespan on all metals, including heat-sensitive alloys.
