3M 7100115525 Laser Braze Finishing Wheel 8 Inch

Product Description

The 3M 7100115525 is a unitized non-woven abrasive finishing wheel engineered specifically for blending and finishing laser-brazed seams in automotive production environments. Built with 3M Precision Shaped Grain bonded into an open-web Scotch-Brite non-woven construction, this wheel delivers a faster cut rate and a consistent surface finish compared to conventional abrasive wheels. It is designed for use on Silicon Bronze and similar metals where surface quality after laser brazing is critical to downstream assembly or coating processes. The wheel measures 8.63 inches in diameter and 2.63 inches wide, and weighs 3.17 pounds.

This wheel is intended for automated and semi-automated finishing lines in automotive body manufacturing, where laser brazing is used to join roof panels, tailgates, and similar structural components. Its flexible, open-web construction is well-suited to robotic finishing cells as well as manual grinding applications requiring consistent stock removal without aggressive surface damage. Technicians and production operators working with Silicon Bronze joints will find this wheel appropriate for blending weld bead crowns and removing surface irregularities prior to paint preparation.

Key Features

• Precision Shaped Grain abrasive provides a fast cut rate and smooth surface finish on Silicon Bronze
• Open-web construction resists loading, extending effective service life between wheel changes
• Flexible non-woven material reduces the need for frequent recalibration and machine adjustments
• Unitized wheel construction maintains consistent performance as the wheel wears
• Sized at 8.63 inches diameter by 2.63 inches wide for compatibility with standard bench and angle finishing setups

Compatibility

Designed as a direct-fit finishing wheel for laser brazing blending applications on Silicon Bronze and similar non-ferrous metals in automotive production; verify arbor bore and RPM rating against your grinder or finishing machine specifications before installation.

Installation Notes

Installation should be performed by a qualified operator following the machine manufacturer's mounting instructions. Disconnect and lock out all power to the finishing machine before mounting or removing the wheel. Confirm that the machine's rated RPM does not exceed the maximum RPM marked on the wheel. Inspect the wheel for cracks or damage before each use and never use a damaged wheel.
