3M 7010326057 Abrasive Belt 72 Inch Aluminum Oxide Gray

Product Description

The 3M 7010326057 is a Trizact 237AA coated abrasive belt designed for intermediate finishing and fine polishing in precision metalworking applications. It uses 3M microreplication technology, where micron-graded aluminum oxide mineral is formed into three-dimensional pyramids and bonded to an X-weight cloth backing. As the pyramids wear during use, fresh cutting edges are continuously exposed, delivering a consistent cut rate and predictable surface finish throughout the belt's service life. The belt measures 72 inches in length and 2.5 inches in width and weighs approximately 0.37 pounds.

This belt is intended for use in grinding, finishing, and polishing operations on metal workpieces prior to plating or buffing. The flexible cloth backing conforms to contoured surfaces, making it suitable for both flat stock and profiled parts. Its three-dimensional abrasive structure supports consistent performance in automated and robotic finishing systems, reducing variation between passes and extending usable belt life compared to conventional electrostatically coated abrasives.

Key Features

• Microreplication technology forms aluminum oxide into self-sharpening pyramids that expose fresh mineral as they wear
• Runs cooler than conventional abrasives, reducing heat buildup on workpiece surfaces
• X-weight cloth backing provides flexibility for finishing over contoured geometry
• Three-dimensional abrasive design supports repeatable finishes in robotic and automated applications
• Produces finer surface finishes than standard electrostatically coated abrasive belts
• Suited for intermediate finishing and fine polishing prior to plating or buffing operations

Compatibility

Designed for use on belt grinding and finishing machines that accept a 72-inch by 2.5-inch abrasive belt. Suitable for metalworking applications involving ferrous and non-ferrous workpieces requiring controlled surface finish prior to secondary operations.

Installation Notes

Installation should be performed by qualified personnel following the machine manufacturer's belt-change procedure. Power down and lock out the machine before removing or installing the belt. Confirm correct belt tracking and tension before resuming operation. Inspect the contact wheel and platen for wear or contamination that could affect finish quality.
