3M 7100018917 Surface Conditioning Belt 79x3 Inch Ao

Product Description

The 3M 7100018917 is a nonwoven surface conditioning belt designed for precision metalworking tasks including blending, deburring, contour finishing, flat finishing, and stainless steel finishing. Built with an aluminum oxide abrasive bonded in resin onto a scrim-reinforced nonwoven open web, this belt delivers consistent material removal without the loading and heat buildup common to conventional abrasive belts. The open web construction reduces clogging on ferrous and non-ferrous metals alike, allowing longer run times between belt changes. It is installed and operated by metalworkers, fabricators, and finishing technicians working on manual and automated belt grinder setups.

This belt is suited for both manual finishing operations and robotic or automated processing applications where conformability to complex part geometries is required. Typical use cases include setting grain on stainless steel panels, removing grind lines and mill marks, blending weld seams, and achieving straight-line brushed finishes on flat and contoured metal surfaces. The 79 inch length and 3 inch width fit standard wide-belt and pipe-finishing machines configured for that size.

Key Features

• Nonwoven open web construction reduces loading and heat buildup for extended operating life
• Aluminum oxide abrasive in resin bond delivers consistent surface conditioning on a range of metals
• Scrim-reinforced backing provides flexibility for detail work over contours and edges
• Conformable structure keeps abrasive in contact with complex-shaped parts in robotic processing
• Removes surface imperfections, grind lines, mill marks, and weld discoloration
• Suitable for blending, deburring, cleaning, flat finishing, and stainless steel finishing applications

Compatibility

Designed to fit belt finishing machines and pipe-finishing equipment configured for a 79 inch length by 3 inch width belt. Verify machine specifications before installation.

Installation Notes

Installation should be performed by a qualified metalworking or fabrication technician. Power down and lock out the belt grinder before changing belts. Confirm the machine is rated for the belt dimensions and operating speed before running. Inspect the belt for tears or damage before each use and do not operate a damaged belt.
