3M 7000045605 Abrasive Belt 148x2.25 Inch Ao Rayon

Product Description

The 3M 7000045605 is a Trizact 307EA coated abrasive belt designed for intermediate finishing and fine polishing applications. It uses 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 down during use, fresh, sharp mineral is continuously exposed, delivering a consistent cut rate and a predictable, fine surface finish across the full life of the belt. The belt measures 148 inches in length and 2.25 inches in width and weighs 0.33 pounds. It is well suited for robotic and automated finishing lines where finish consistency is critical.

This belt is intended for metal finishing operations including intermediate stock removal, fine finishing, and surface preparation prior to plating or buffing. The flexible rayon cloth backing conforms to contoured and curved workpiece surfaces, making it appropriate for both flat and shaped components. It is commonly used in fabrication shops, metal finishing facilities, and manufacturing environments where tight finish tolerances are required across high production volumes.

Key Features

• Microreplication technology forms aluminum oxide into self-sharpening three-dimensional pyramids for consistent cut throughout belt life
• Self-sharpening pyramid structure runs cooler than conventional abrasive coatings, reducing heat-related workpiece distortion
• Flexible rayon cloth backing conforms to contoured surfaces for uniform contact and consistent finish
• Produces finer surface finishes than conventional electrostatically coated abrasive belts
• Three-dimensional abrasive design maintains finish consistency in robotic and automated applications
• Suited for intermediate finishing and fine polishing before plating or buffing operations

Compatibility

Designed as a replacement-style abrasive belt for industrial belt grinders and finishing machines that accept a 148-inch by 2.25-inch belt configuration.

Installation Notes

Belt installation should be performed by a qualified operator following the machine manufacturer's tracking and tensioning guidelines. Power down and lock out the belt grinder before changing the belt. Verify belt tracking on a slow-speed jog cycle before running at full operating speed. Inspect the platen or contact wheel for wear or damage before installing a new belt to ensure even contact across the abrasive surface.
