3M 7000028335 Abrasive Belt 15.5x3.5 Inch Ao Cloth

Product Description

The 3M 7000028335 is a Trizact 237AA abrasive belt designed for intermediate finishing and fine polishing applications. It uses 3M microreplication technology, where micron-graded aluminum oxide particles are formed into precise three-dimensional pyramids and bonded to an X weight cloth backing. As the pyramids wear down, fresh cutting mineral is continuously exposed, delivering a consistent cut rate and a predictable, fine surface finish throughout the belt's usable life. This belt measures 15.5 inches in length and 3.5 inches in width and is suited for use in automated, robotic, or hand-finishing operations across metalworking and fabrication environments.

This belt is used in industrial finishing applications including intermediate stock removal and fine polishing prior to plating, buffing, or coating. The flexible cloth backing conforms to contoured surfaces, making it effective on complex geometries. It is commonly specified in metalworking shops, fabrication facilities, and production finishing lines where repeatable surface finish quality is required. The three-dimensional abrasive structure is particularly well suited for robotic belt grinding systems where consistent finish throughout abrasive life is critical.

Key Features

• Microreplication technology forms aluminum oxide into self-sharpening abrasive pyramids for a consistent cut
• Fresh mineral is continuously exposed as pyramids wear, maintaining cut rate and finish quality
• Runs cooler than conventional abrasives, reducing heat buildup on workpiece surfaces
• X weight cloth backing provides flexibility for finishing over contours and complex profiles
• Produces finer finishes than conventional electrostatically coated abrasive belts
• Suitable for robotic and automated finishing applications requiring predictable, repeatable results

Compatibility

Designed for use on belt finishing machines and robotic grinding systems that accept 15.5 inch by 3.5 inch abrasive belts. Typical applications include intermediate finishing and fine polishing of metal workpieces prior to plating or buffing operations.

Installation Notes

Install and replace abrasive belts only after the machine has been fully powered down and brought to a complete stop. Verify belt tracking and tension according to the equipment manufacturer's specifications before resuming operation. Inspect the belt for tears, delamination, or edge damage before each use. Abrasive belt replacement in production environments is typically performed by machine operators or maintenance technicians following applicable shop safety procedures.
