3M 7000118657 Abrasive Belt 34x2 Inch Ao Cloth Gray

Product Description

The 3M 7000118657 is a Trizact 237AA coated abrasive belt designed for intermediate finishing and fine polishing applications in metalworking and fabrication environments. It uses 3M microreplication technology, where micron-graded aluminum oxide abrasive particles are formed into uniform three-dimensional pyramids and bonded to an X-weight cloth backing. As the pyramids wear during use, fresh, sharp mineral is continuously exposed, delivering a consistent cut rate and a predictable, fine surface finish across the life of the belt. At 34 inches long and 2 inches wide, this belt fits standard belt finishing machines used in metal fabrication and polishing operations.

This belt is suited for intermediate stock removal, fine finishing, and pre-plate or pre-buff polishing on metal components. The flexible cloth backing conforms to contoured workpiece surfaces, making it appropriate for both flat and profile work. Its consistent, three-dimensional abrasive structure also makes it well-suited for robotic and automated finishing lines where repeatable surface finish results are required across high production volumes.

Key Features

• Microreplication technology forms aluminum oxide into self-sharpening pyramidal structures that expose fresh mineral as they wear
• Runs cooler than conventional coated abrasives, reducing heat buildup on workpieces
• X-weight cloth backing provides flexibility for finishing over contoured surfaces
• Three-dimensional abrasive design delivers consistent finishes throughout belt life, including in robotic applications
• Produces finer surface finishes than conventional electrostatically coated abrasive belts
• Suitable for intermediate finishing and fine polishing prior to plating or buffing

Compatibility

Designed for use on standard belt finishing and polishing machines accepting 34-inch by 2-inch abrasive belts; suitable for metalworking applications requiring fine finishing or pre-plate surface preparation.

Installation Notes

Belt installation and replacement should be performed by qualified personnel familiar with abrasive belt machinery. Power down and lock out the machine before changing belts. Verify belt tracking and tension per the machine manufacturer's guidelines before resuming operation. Inspect the belt for tears or delamination before each use and discard damaged belts immediately.
