3M 7010328655 Trizact 237AA Abrasive Belt 90x3 Inch Ao

Product Description

The 3M 7010328655 is a Trizact 237AA coated abrasive belt designed for intermediate finishing and fine polishing in industrial and metalworking applications. It uses 3M microreplication technology, where micron-graded aluminum oxide particles are formed into three-dimensional pyramids and bonded to an X-weight cloth backing. As the pyramids wear during use, fresh abrasive mineral is continuously exposed, delivering a consistent cut rate and predictable surface finish throughout the life of the belt. This belt is 90 inches long and 3 inches wide, suited for wide-contact belt grinding and polishing machines.

This belt is used in applications that require controlled, fine surface finishes prior to plating, buffing, or anodizing. The flexible cloth backing conforms to contours, making it effective on curved or profiled workpieces. It is particularly well-suited for robotic and automated grinding lines where finish consistency across the full belt life is critical. Metalworking shops, aerospace component finishers, and precision grinding operations are typical environments for this product. It is installed and operated by machinists, grinding technicians, and industrial finishing personnel.

Key Features

• Microreplication technology forms aluminum oxide into self-sharpening abrasive pyramids for consistent cut and finish
• Self-sharpening design runs cooler than conventional coated abrasives, reducing heat buildup on the workpiece
• X-weight cloth backing provides flexibility for finishing over contours and profiles
• Three-dimensional abrasive structure delivers repeatable finishes throughout belt life, critical for robotic applications
• Produces finer surface finishes than conventional electrostatically coated abrasive belts
• Designed for intermediate finishing and fine polishing prior to plating or buffing operations

Compatibility

Designed for use on belt grinding and polishing machines that accept 90-inch by 3-inch abrasive belts. Suitable for ferrous and non-ferrous metal substrates in intermediate finishing and pre-plate polishing operations.

Installation Notes

Installation should be performed by qualified grinding or finishing technicians following the machine manufacturer's belt-tracking and tensioning procedures. Power down and lock out the machine before changing belts. Verify belt direction of travel matches the arrow marked on the belt backing before starting the machine. Inspect the platen, contact wheel, and idler for wear or damage before installing a new belt.
