3M 7100117439 Scotch-brite Laser Braze Unitized Wheel 3 in

Product Description

The 3M 7100117439 is a unitized non-woven finishing wheel engineered to blend and finish the surface imperfections left by laser brazing in automotive production environments. Built on an open-web Scotch-Brite non-woven construction and loaded with 3M Precision Shaped Grain abrasive, this wheel delivers a faster cut rate and a consistently smooth finish on Silicon Bronze and comparable metals. At 3 inches in diameter and weighing 1.78 pounds, it is sized for automated and semi-automated finishing operations where tight access and consistent material removal are both critical. Installation and operation are typically handled by production technicians or grinding specialists working within established automotive finishing processes.

This wheel is intended for laser braze finishing applications in automotive body production, particularly where Silicon Bronze filler is used to join panels or roof lines. The open-web structure resists loading from soft non-ferrous metals, extending effective wheel life between changeovers. It is sold in a minimum quantity of 40 units per order, reflecting its suitability for high-volume production line use rather than one-off repair work.

Key Features

• Designed specifically to blend and finish Silicon Bronze laser braze joints on automotive panels
• 3M Precision Shaped Grain abrasive provides faster cutting action and longer service life compared to conventional abrasive grains
• Open-web non-woven construction resists loading on soft metals, reducing downtime from frequent wheel changes
• Flexible Scotch-Brite material conforms to surface contours and reduces the need for recalibration or process adjustments
• Unitized wheel construction maintains consistent performance and finish quality throughout the wheel's life

Compatibility

Designed for use on Silicon Bronze and similar non-ferrous metals in laser brazing finishing applications; intended for automated or semi-automated production grinding equipment accepting a 3-inch diameter unitized wheel.

Installation Notes

Installation should be performed by a qualified production technician or tooling specialist following equipment lockout/tagout procedures before mounting or removing the wheel. Verify that the spindle speed of the host machine does not exceed the maximum rated RPM marked on the wheel or its packaging before operating. Inspect the wheel for damage before each use and replace immediately if cracking, delamination, or uneven wear is observed. Follow all applicable ANSI and OSHA grinding safety standards during setup and operation.
