3M 7010328216 Trizact 307EA Abrasive Belt 15.5x3.5 in

Product Description

The 3M 7010328216 is a Trizact 307EA abrasive cloth belt designed for intermediate finishing and fine polishing on metal and contoured surfaces. It uses 3M microreplication technology in which micron-graded aluminum oxide particles are formed into three-dimensional pyramids and bonded to a flexible rayon backing. As the pyramids wear down during use, fresh abrasive mineral is continuously exposed, maintaining a consistent cut rate and producing a predictable, fine surface finish throughout the life of the belt. The gray color indicates the aluminum oxide mineral system. This belt is well suited for automated and robotic finishing lines as well as manual applications.

This belt is used in intermediate and fine finishing operations prior to plating, buffing, or coating. The flexible rayon backing conforms to contoured and irregular workpiece profiles, making it applicable in metal fabrication, aerospace component finishing, and precision part preparation. Its three-dimensional abrasive structure supports consistent finish quality in high-volume robotic applications where repeatability is critical. It is commonly installed and used by metal finishing technicians, fabricators, and automated grinding system operators.

Key Features

• Microreplication technology forms aluminum oxide into self-sharpening abrasive pyramids for consistent cut throughout belt life
• Fresh mineral is continuously exposed as pyramids wear, reducing heat buildup compared to conventional coated abrasives
• Flexible rayon backing conforms to contoured and irregular surfaces for uniform finishing
• Three-dimensional abrasive design supports repeatable finish quality in robotic and automated applications
• Produces finer surface finishes than conventional electrostatically coated abrasive belts
• Suited for intermediate finishing and fine polishing prior to plating or buffing operations

Compatibility

Designed as an OEM-style replacement or standard supply belt for belt grinders and finishing machines accepting a 15.5-inch by 3.5-inch belt size.

Installation Notes

Installation should be performed by a qualified metal finishing technician or machine operator familiar with belt grinding equipment. Power down and lock out the machine before changing the belt. Verify belt tracking and tensioner settings per the equipment manufacturer guidelines before resuming operation. Inspect the belt for tears or edge damage before each use.
