For increased performance and prolonged service life, use 3M™ Cubitron™ ll Cloth Belt 723D. With premium aluminium oxide blended with 3M™ Precision Shaped Grain, our cloth belts deliver increased durability and cutting efficiency over non-ceramic abrasives.
The backing is a flexible cotton cloth that easily follows contours and can wrap around parts to avoid over grinding. As a result, these cloth belts are ideal for removing defects and surface imperfections, even on tight contours and complex parts such as medical instruments. Flexibility also makes this belt a good choice when using a soft contact wheel or slack belt.
The science of 3M precision shaped grain
Precision shaped grain signifies a major advancement in abrasive technology. PSG is a ceramic mineral designed using a proprietary process to enhance the toughness and strength of the grain. 3M scientists then went one step further and precisely engineered the mineral to form uniform triangular shaped grains that continually fracture into super sharp points and edges. This allows them to slice through the substrate, rather than gouging or ‘ploughing’ like conventional abrasives. PSG creates a super-fast cut and lessens heat build-up in the workpiece, reducing heat related stress cracks and discolouration. Moreover, because PSG stays cooler and sharper, it lasts longer than conventional abrasives.
For increased performance, 723D belts feature premium aluminium oxide blended with 3M PSG for a sharper, longer lasting abrasive. This not only delivers more consistent performance, but also provides up to two times longer life than comparable aluminium oxide belts. Longer life means lower cost per finished part, and less time lost to belt changeovers, giving greater productivity.
Loading occurs when wood or paint dust clogs the surface of the belt and the abrasive points, rendering the belt ineffective. Open coat construction means the abrasive grains are spaced slightly apart so that dust and debris have an outlet rather than loading the abrasive. Additionally, the open coat feature provides a more aggressive cut than a comparable closed coat abrasive of the same grade. The abrasive is firmly bonded to the backing with resin to maintain durability under high heat and pressure.
For more than 100 years 3M has been a leading abrasive supplier of the metalworking industry. Regardless of your grinding and finishing applications, 3M offers a full line of quality coated and bonded abrasives. 3M engineers designed these cloth belts with the flexibility required for finishing complex parts while delivering rapid cut and long lasting performance. They are an excellent choice when you need a finishing belt that stands up to the demands of production environments.
