3M 7100115938 Unitized Laser Braze Finishing Wheel 4 Inch

Product Description

The 3M 7100115938 is a unitized non-woven abrasive finishing wheel engineered specifically for blending and finishing imperfections produced by laser brazing in automotive manufacturing environments. Built with Scotch-Brite non-woven material combined with 3M Precision Shaped Grain, the wheel delivers a faster cut rate and longer service life compared to conventional abrasive options. The open web construction resists loading, keeping the wheel cutting cleanly through Silicon Bronze and similar metals. Licensed technicians and production line operators working in automotive body and fabrication applications will find this wheel suited for consistent, repeatable surface finishing results.

This wheel is intended for automated and manual finishing operations where laser-brazed seams on automotive body panels require blending to a smooth, uniform surface. The flexible non-woven construction allows the wheel to conform to contoured surfaces without requiring frequent recalibration or machine adjustment, reducing downtime on production lines. It is particularly effective on Silicon Bronze substrates common in automotive roof ditch and door hem brazing applications.

Key Features

• Designed specifically to blend and finish Silicon Bronze laser-brazed seams in automotive production
• Open web construction resists loading and extends effective service life
• 3M Precision Shaped Grain provides a faster cut rate and smooth surface finish
• Flexible Scotch-Brite non-woven material conforms to contoured surfaces and reduces need for recalibration
• Unitized construction delivers consistent performance throughout the life of the wheel

Compatibility

Designed for use on Silicon Bronze and similar metals in laser brazing finishing applications, particularly in automotive manufacturing and fabrication environments.

Installation Notes

This wheel is mounted and operated by qualified fabrication or production technicians familiar with abrasive wheel safety standards. Always power down and lock out the drive spindle before mounting or removing the wheel. Verify that the spindle speed rating of the machine does not exceed the rated speed of the wheel before operation. Follow applicable ANSI abrasive wheel safety standards and wear appropriate personal protective equipment including eye and face protection.
