Unitized Wheels - AA Abrasives, Inc.

Unitized Wheels

AA Abrasives’ Unitized Wheels are designed to improve quality, increase productivity, and lower manufacturing costs. These multi finishing grinding wheels are excellent for cleaning, deburring, blending, finishing, and polishing. The structure of Unitized Wheels  minimizes heat build up to extend wheel life.  These wheels are less conforming than other preparation wheels to ensure a more consistent and uniform finish.

Unitized wheels are constructed by bonding and compressing layers of abrasives impregnated with non-woven nylon making it more aggressive than a Surface Prep Wheel. On a flat surface a unitized wheel will outlast the surface prep wheel making it a more efficient method for deburring, polishing and cleaning.

AA Abrasives, Inc. carries three types of Unitized Wheels.

2SF - is a softer less aggressive unitized wheel made with silicon carbide and is considered a fine.  This specific wheel is used in applications calling for a very fine non aggressive finish. Specifications: 4-1/2x7/8 #2SF Grey T-27 11,000 RPM  Item #33735.

Suggested Application for a 2SF unitized wheel - polishing mechanical parts such as blades, welds and threads or softer metals such as brass, aluminum, and copper. 

3SF - is considered a medium-soft silicon carbide fine grit. Specifications: 4-1/2x7/8 #3SF Grey T-27 11,000 RPM  Item #33736.

Suggested Application for a 3SF unitized wheel is cleaning heavy scale and oxidation on alloys, titanium and stainless.  

2AM - is considered a medium density with an aluminum oxide grain. This unitized wheel is the most aggressive and is recommended on heavier steels such as carbon and stainless steel. Specifications:  4-1/2x7/8 #2AM Tan T-27 11,000 RPM  Item #33737.

Suggested Application for the 2AM  unitized wheel - heavy blending or substantial burr marks on heavier steel. The 2AM unitized wheel will work on sharpened edges.

Use these unitized wheels on a variable speed grinder such as a Walter Big Buff 30-A-265 

or a Metabo 14-125VS Variable speed . You can decrease the RPM for duller finishes and polishes.
