3M 7010328663 Abrasive Belt 90x4 Inch Aluminum Oxide Gray

Product Description

The 3M 7010328663 is a Trizact 307EA cloth abrasive belt built for intermediate finishing and fine polishing in demanding production environments. It uses microreplication technology where micron-graded aluminum oxide mineral is formed into uniform three-dimensional pyramids and bonded to a flexible rayon cloth backing. As the pyramids wear during use, fresh sharp cutting points are continuously exposed, producing a consistent cut rate and a predictable fine finish from the first pass to the last. At 90 inches long and 4 inches wide, this belt fits wide-contact and slack-section belt grinding setups common in metalworking and finishing lines.

This belt is designed for metalworking applications requiring consistent surface finish quality, particularly in robotic or automated finishing systems where repeatable results are critical. It is well suited for intermediate stock removal and fine polishing steps prior to electroplating or buffing operations. The flexible rayon cloth backing conforms to contoured and irregular workpiece profiles, making it effective on parts that require edge-to-edge contact across complex geometry. Machinists, fabricators, and finishing line operators are the primary installers and users of this product.

Key Features

• Microreplication technology forms aluminum oxide mineral into self-sharpening pyramids for consistent cut throughout belt life
• Flexible rayon cloth backing conforms to contoured surfaces for uniform contact and finish
• Three-dimensional abrasive structure delivers repeatable finishes in robotic and automated finishing applications
• Ideal for intermediate finishing and fine polishing prior to plating or buffing operations
• Produces finer surface finishes than conventional electrostatically coated abrasive belts
• Runs cooler than conventional abrasives, reducing heat-related workpiece distortion risk

Compatibility

Designed for use on belt grinding and finishing machines accepting a 90-inch by 4-inch abrasive belt configuration, typically in industrial metalworking and surface conditioning applications.

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 grinding machine before mounting or removing the belt. Verify belt direction-of-travel arrows align with machine rotation before startup. Inspect the contact wheel and platen for wear or damage before installing a new belt.
