NEW LOT of 50 belts 3M 947A 3/4"x18" 80+ Grit X-Wt Cubitron II File Belt 94710

Description

3M Cubitron ll Cloth Belt 947A
The 3M Cubitron II Abrasive Belt 947A built with 3M Precision-Shaped Grain cuts metal dramatically faster and cooler, and stays sharp longer than conventional ceramic belts. Its X-weight poly-cotton backing is flexible. This belt is optimized for low and medium pressure applications on stainless steel, mild steels, and aluminum.
3M Precision-Shaped Grain slices through metals like a knife rather than gouging or plowing
Removes material faster, with less pressure
Includes a grinding aid for less grinding friction and cooler cutting
Cool cutting action lessens the risk of heat-related damage to workpiece
An X-weight poly-cotton backing is optimized for flexibility
Lasts up to 4 times longer than conventional ceramic belts
3M Science. The Beginning of Cubitron II.
In 2009, 3M scientists had long believed abrasives would work better if each grain of the ceramic abrasive material was exactly the same size and shape. It would act more like a knife shaving off material and less like a plow bouncing along the surface, creating heat damage. The breakthrough came when they realized they could use microreplication technology 3M was already using to create reflective material for signs, and other purposes. Within a short time, they had created 3M's Precision Shaped Grain — identical triangular-shaped abrasive grains electrostatically oriented and distributed uniformly on an abrasive backing. The end result is faster, cooler cutting action, improved productivity, less operator fatigue and longer belt life.
How 3M Precision-Shaped Grain Works
3M Precision-Shaped Grain is designed to continuously fracture to form sharp points and edges that easily 'slice' through metal. It cuts faster, lasts longer and stays cooler. Conventional ceramic abrasive grain tends to 'plow' through the metal, causing heat to build up in the workpiece and the abrasive – resulting in a slower cut, shorter belt life and undesirable effects, such as burnishing.
Fast and Flexible
A closed coat and a grinding aid make the 3M Cubitron II Abrasive Belt 947A an outstanding option for low to medium pressure applications on heat sensitive metals. The nature of the abrasive structure diverts heat to the swarf, keeping both belt and workpiece cooler. It is now available in grades 40+ (make to order), 60+, 80+ and now 120+ adding an improved solution for finer finishing applications.
Cutting Edge Performance for Low and Medium Pressure Sanding
A semi flexible Cubitron II belt the 3M 947A sports an X-weight poly-cotton backing. Among backing weights, an X-weight cloth is flexible and provides tensile strength as well. A great number of small belt sizes which are nimble and maneuverable so operators can get in, over and around intricate parts. These belts are good options for low-and-medium-pressure offhand operations for use on the following equipment:
Backstands.
File Belt Sanders.
Inline Sanders.
Stroke Sanders.
Delivers outstanding results on applications ranging from high-pressure, automated grinding to low and medium pressure offhand operations, on equipment including: Backstands, File Belt Sanders, Inline Sander, and Stroke Sanders.
