3M 7000118644 Abrasive Belt 18x0.5 Inch Aluminum Oxide

Product Description

The 3M 7000118644 is a Trizact 237AA coated abrasive belt designed for intermediate finishing and fine polishing in demanding metalworking applications. It uses 3M microreplication technology, forming micron-graded aluminum oxide mineral into precision three-dimensional pyramids bonded to an X weight cloth backing. As the pyramids wear down, fresh sharp mineral is continuously exposed, delivering a consistent cut rate and predictable finish throughout the belt's service life. Weighing 0.02 pounds, this belt measures 18 inches in length and 1/2 inch in width and is sold individually.

This belt is suited for robotic and automated finishing lines where consistent, repeatable surface finishes are critical, as well as manual operations requiring fine polishing prior to plating or buffing. The flexible X weight cloth backing conforms to contoured surfaces, making it appropriate for components with complex geometry. Metalworking shops, fabrication facilities, and precision finishing operations handling stainless steel, aluminum, and similar alloys will find this belt fits standard narrow-belt finishing equipment.

Key Features

• Microreplication technology forms aluminum oxide into self-sharpening three-dimensional pyramids for consistent mineral exposure
• Self-sharpening pyramid structure runs cooler than conventional abrasive coatings, reducing heat buildup on workpiece
• Produces finer, more consistent finishes than conventional electrostatically coated abrasive belts
• Flexible X weight cloth backing conforms to contoured and complex surfaces
• Designed for intermediate finishing and fine polishing prior to plating or buffing operations
• Three-dimensional abrasive design supports consistent performance in robotic finishing applications

Compatibility

Designed as a replacement-style narrow abrasive belt for standard belt finishing machines and robotic finishing systems accepting an 18-inch by 1/2-inch belt configuration.

Installation Notes

Installation should be performed by qualified finishing equipment operators following the machine manufacturer's belt change procedure. Power down and lock out the finishing unit before replacing the belt. Verify belt tracking and tension per equipment specifications before resuming operation. Ensure the belt arrow or grain direction marking, if present, aligns with the direction of travel on the machine.
