3M™ Cubitron™ II Cloth Belt 784F

3M™ Cubitron™ II Cloth Belt 784F features 3M Precision Shaped Ceramic Grain for longer life and a faster, more consistent cut than aluminum oxide belts. A precise mix of shaped ceramic and premium aluminum oxide delivers optimal cut in medium pressure grinding and blending applications. The sanding belt also features a waterproof backing and grinding aid.We engineered our 3M Cubitron II Cloth Belt 784F with medium pressure industrial applications in mind, using 3M Precision Shaped Ceramic Grain (PSG), which cuts exceptionally fast and self-renews 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 grits 36+-80+ have a YF-weight backing, while finer grits of 120+-180+ have a lighter XF-weight backing. Both weights are moderately flexible and conform well to slight contours and flat surfaces. With its water-resistant polyester backing, 3M Cubitron II Cloth Belt 784F 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 discolouration, we 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. 3M Precision Shaped Ceramic Grain signifies a major advancement in abrasive technology. PSG is a ceramic mineral designed using a proprietary process to enhance toughness and hardness of the grain. 3M scientists then 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. PSG creates a super-fast cut and lessens heat build-up on the workpiece, reducing heat-related stress cracks and discoloration. Moreover, because PSG stays cooler and sharper, it lasts longer than conventional abrasives. For increased performance, 3M Cubitron II Cloth Belt 784F features premium aluminum oxide blended with PSG for a sharper, longer-lasting abrasive. This not only delivers more consistent performance, but also provides up to 2x longer life than comparable aluminum oxide belts. Longer life means lower cost per finished part and less time lost to belt changeovers, maximizing throughput.
