3M 7010328218 Trizact 307EA Abrasive Belt 118x4 Inch Ao

Product Description

The 3M 7010328218 is a Trizact 307EA abrasive belt designed for precision intermediate finishing and fine polishing operations. It uses microreplication technology in which micron-graded aluminum oxide particles are formed into uniform three-dimensional pyramids and bonded to a flexible rayon cloth backing. As the pyramids wear during use, fresh sharp mineral is continuously exposed at the cutting surface. The result is a consistent cut rate and a predictable, fine surface finish that holds steady from the start of the belt's life to the end. This belt measures 118 inches in length and 4 inches in width and is sold individually.

This belt is suited for industrial finishing environments including robotic and automated grinding lines where finish consistency across long production runs is critical. It performs well on contoured and flat metal surfaces prior to plating, buffing, or final inspection. Typical applications include intermediate stock removal and fine polishing on steel, stainless, and non-ferrous metals. The flexible rayon backing conforms to curved workpiece profiles without loading or glazing, making it a practical choice for high-volume metal fabrication and precision manufacturing shops.

Key Features

• Microreplication technology forms aluminum oxide into uniform abrasive pyramids for self-sharpening action
• Fresh mineral is continuously exposed as pyramids wear, maintaining consistent cut rate throughout belt life
• Runs cooler than conventional coated abrasives, reducing heat-related workpiece damage
• Flexible rayon cloth backing conforms to contoured and complex surface geometries
• Three-dimensional abrasive structure delivers repeatable finishes in robotic and automated applications
• Produces finer surface finishes than conventionally electrostatically coated abrasive belts

Compatibility

Designed as an OEM-style replacement or direct-use abrasive belt for industrial belt grinders and finishing machines accepting a 118 inch by 4 inch belt configuration.

Installation Notes

Installation should be performed by qualified machine operators or maintenance personnel following the equipment manufacturer's belt-tensioning and tracking procedures. Power down and lock out the grinder or finishing machine before changing the belt. Verify belt direction-of-travel arrow aligns with the machine's drive direction before resuming operation. Inspect the contact wheel and platen for wear or damage that could compromise belt tracking or finish quality.
