With the improvement of technological level and automation polishing demand in the industrial field, higher quality requirements pose significant challenges to traditional polishing processes. In the field of industrial grinding, abrasive belts, as one of the common grinding tools, are widely used in various fields of grinding and processing. According to the different material, morphology, and grinding pressure of the workpiece, sand belt products also have different requirements for various properties such as soft hardness of the backing, cutting efficiency, and so on. 3M breakthrough abrasive Cubitron ? The first combination of II and flexible fabric backing makes the 3M abrasive belt product line more complete.

3M 726A soft cloth based abrasive belt is a strong cutting soft cloth based abrasive belt with better adhesion, stronger cutting force, and longer service life. It adopts Cubitron ? II ceramic abrasive is a 3M specific ceramic alumina second-generation precision forming abrasive, with its unique triangular mineral sand particles giving the abrasive belt excellent cutting force.

These triangular ceramic mineral sands have good self sharpening properties, and can break into new sharp corners after surface wear, cutting metal flat like a knife, effectively preventing slipping and burning of the workpiece due to sand belt blockage and heat accumulation during grinding.

And Cubitron ? The II 726A grinding sand belt uses precision formed mineral sand, which has higher cutting force during the workpiece polishing process. When combined with a flexible backing, it has a softer and tear resistant feel, and the polishing effect is even. It can significantly reduce the replacement frequency of the sand belt, improve the polishing efficiency, and have a higher cost-effectiveness.

At the same time, there are also 423A carbide soft cloth based sand belt products with a wider particle size range.

The 423A uses selected silicon carbide mineral sand, paired with a flexible polyester cotton blended back base, which has higher cutting force, stronger tear resistance, and ensures a soft feel. The sand belt has a full range of particle sizes ranging from P120 to P1000, all meeting the FEPA particle size standards, providing a more uniform polishing effect.

It is widely used in fields such as artificial implants and medical devices, aviation blades and parts, bathroom, kitchen and sports hardware, hardware tools and cutting tools, bicycle parts, and automated polishing.
