3M 7100115840 Unitized Laser Braze Finishing Wheel 4 in

Product Description

The 3M 7100115840 is a unitized non-woven abrasive finishing wheel engineered specifically to blend and finish imperfections produced by laser brazing in automotive manufacturing environments. Built on Scotch-Brite open-web non-woven material and loaded with 3M Precision Shaped Grain, the wheel delivers faster cutting action and a consistent surface finish compared to conventional abrasive wheels. At 4 inches in diameter, it is sized for bench-mounted or automated finishing applications. Automotive body and metal fabrication professionals install this wheel where silicon bronze and similar metals require uniform surface blending after laser braze joints are completed.

This wheel is primarily used in automotive production lines and fabrication shops where laser brazing of silicon bronze panels and components is standard practice. The unitized construction keeps the abrasive mineral distributed evenly throughout the wheel body rather than only at the surface, which means cutting performance remains consistent as the wheel wears down. It suits applications that demand a smooth, controlled finish on brazed seams without altering the surrounding base metal.

Key Features

• Precision Shaped Grain construction delivers faster cut rate and longer service life than conventional abrasive grain
• Open-web non-woven material resists loading and clogging during silicon bronze finishing
• Flexible wheel body reduces the need for machine recalibration between passes
• Unitized design provides consistent abrasive performance throughout the full wheel life
• 4-inch diameter suits standard bench and automated finishing setups in production environments

Compatibility

Designed for blending and finishing silicon bronze and similar metals in laser brazing applications, particularly in automotive body production environments.

Installation Notes

This wheel is installed by metal finishing technicians and automotive production personnel on bench grinders or automated finishing equipment rated for the wheel diameter and speed. Confirm the machine spindle speed does not exceed the maximum rated RPM marked on the wheel before mounting. Power down and de-energize the finishing equipment completely before mounting or changing the wheel. Inspect the wheel for damage before each use and do not use a wheel that shows cracking, delamination, or uneven wear.
