3M 7100136379 Scotch-brite Laser Braze Unitized Wheel 8 in

Product Description

The 3M 7100136379 Scotch-Brite Laser Braze LB-UW is a unitized non-woven finishing wheel engineered to blend and finish imperfections produced by laser brazing in automotive manufacturing environments. At 8 inches in diameter, the wheel combines open-web Scotch-Brite non-woven construction with 3M Precision Shaped Grain abrasive technology, delivering a faster cut rate alongside a consistently smooth surface finish. Weighing 3.11 pounds, it is built for production-level use on Silicon Bronze and other metal substrates. Metalworkers and fabricators in automotive finishing operations rely on this wheel for high-throughput abrasive tasks where surface quality directly affects downstream assembly.

This wheel is intended for laser brazing finishing applications in automotive production lines where Silicon Bronze joints require blending to meet surface quality standards. The flexible non-woven construction conforms to workpiece contours, making it well suited for curved body panels and seam areas. Its open web design resists material loading, extending wheel service life in continuous production use. It is sold individually and carries a minimum order quantity of 10 units, consistent with production-scale purchasing.

Key Features

• Open-web non-woven construction resists loading and extends effective service life in production environments
• 3M Precision Shaped Grain abrasive delivers a faster cut rate and a smooth, consistent finish on Silicon Bronze and similar metals
• Flexible Scotch-Brite material conforms to workpiece geometry, reducing the need for machine recalibration between passes
• Unitized wheel construction maintains consistent performance throughout the life of the wheel
• 8-inch diameter suits standard production finishing equipment used in automotive fabrication

Compatibility

Designed for use on Silicon Bronze and other metals in laser brazing finishing applications, particularly in automotive body panel production. Consult equipment manufacturer specifications to confirm spindle compatibility before mounting.

Installation Notes

This wheel should be mounted by a qualified operator following the abrasive wheel manufacturer's safety guidelines and applicable ANSI B11 or OSHA 29 CFR 1910.215 standards for abrasive wheel machinery. Inspect the wheel for damage before each use and never exceed the rated maximum operating speed marked on the wheel or its packaging. Ensure the machine is fully de-energized and locked out before changing wheels. Eye protection and appropriate PPE are required during operation.
