3M 7010328232 Trizact 217EA Abrasive Belt 64x1 Inch Ao

Product Description

The 3M 7010328232 is a Trizact 217EA abrasive belt designed for intermediate finishing and fine polishing on metal surfaces. It uses 3M microreplicated pyramid technology, in which micron-graded aluminum oxide particles are formed into uniform pyramid structures on a JE-weight rayon cloth backing. As the pyramids wear during use, fresh, sharp mineral is continuously exposed. This self-renewing action delivers a consistent cut rate and a predictable fine finish throughout the entire belt life. The belt is suited for professional finishing operations, including robotic and automated sanding lines where process consistency is critical.

This belt is used in light-pressure finishing applications on metal workpieces prior to plating or buffing. The flexible JE-weight rayon backing conforms to contoured and curved surfaces, making it practical for both flat stock and shaped components. Its consistent cut and long abrasive life make it well suited for automated or robotic finishing systems where repeatable results are required across high part volumes. A built-in grinding aid helps reduce heat buildup, minimizing the risk of heat-related warping or surface discoloration during extended runs.

Key Features

• Microreplicated aluminum oxide pyramids continuously expose fresh mineral as they wear for consistent cut throughout belt life
• JE-weight rayon cloth backing conforms to contoured surfaces for uniform finishing
• Produces finer finishes than conventional coated abrasive belts
• Grinding aid reduces heat buildup to prevent warping and surface discoloration
• Consistent performance makes it suitable for robotic and automated finishing applications
• Designed for light-pressure intermediate finishing and pre-plate or pre-buff polishing

Compatibility

Designed as a replacement-style abrasive belt for belt sanders and finishing machines that accept 64 inch by 1 inch belts in light-pressure intermediate and fine-polishing operations on metal substrates.

Installation Notes

Belt installation should be performed by qualified personnel following the equipment manufacturer's guidelines for belt tensioning and tracking. Always power down and lock out the belt sander or finishing machine before changing belts. Inspect the contact wheel, platen, and tracking guides for wear or debris before mounting a new belt. Verify belt direction of travel matches the arrow printed on the belt splice if one is present.
