3M 7100034255 Trizact 307EA Abrasive Belt 72x2 Inch Ao

Product Description

The 3M 7100034255 is a Trizact 307EA abrasive belt designed for intermediate finishing and fine polishing applications. It uses 3M microreplication technology in which micron-graded aluminum oxide particles are formed into three-dimensional pyramids and bonded to a flexible rayon cloth backing. As the pyramids wear during use, fresh sharp mineral is continuously exposed, delivering a consistent cut rate and a predictable fine surface finish throughout the life of the belt. The 72-inch length and 2-inch width make it suited for wide-belt finishing equipment used in metalworking and fabrication environments. Fabricators, metalworkers, and finishing technicians are the primary installers and users of this product.

This belt is used in intermediate finishing and fine polishing operations prior to plating or buffing. The flexible rayon backing conforms to contoured and flat surfaces alike, making it effective for both manual and robotic finishing lines. The three-dimensional abrasive structure supports highly repeatable results in automated applications where consistent surface finish is critical across high production volumes.

Key Features

• Microreplication technology forms aluminum oxide into self-sharpening pyramid structures that continuously expose fresh mineral as they wear
• Runs cooler than conventional abrasives, reducing heat-related workpiece distortion
• Flexible rayon cloth backing conforms to contoured surfaces for uniform finishing
• Three-dimensional design delivers consistent finishes throughout abrasive life, supporting robotic and automated applications
• Produces finer finishes than conventional electrostatically coated abrasives
• Suited for intermediate finishing and fine polishing prior to plating or buffing

Compatibility

Designed for use on wide-belt finishing machines accepting 72-inch by 2-inch abrasive belts in metalworking, fabrication, and polishing applications.

Installation Notes

Installation should be performed by qualified finishing or maintenance technicians. Power down and lock out the belt finishing machine before mounting or removing abrasive belts. Verify belt tracking and tension according to the equipment manufacturer guidelines before resuming operation. Inspect the belt for tears or edge damage before each use and replace if defects are found.
