Narrowing It Down3M™ Polishing Film Belt 971X comes in narrow belt converted form. That means it is especially equipped to polish parts with narrow widths. It's commonly used for roll finishing, superfinishing and other fine polishing industrial applications.Essential Ingredients3M™ Polishing Film Belt 971X is a flocked abrasive, which means the fibers are electrostatically coated to the film. Micron-graded aluminum oxide is adhered to the film backing with a slurry coating. Slurry-coated abrasives have abrasive mineral embedded in the resin that binds the mineral to the backing. A slurry-coated abrasive tends to produce a finer finish than coated products in similar grades, because — rather than standing straight up or protruding — the minerals lie inside the resin. A slurry-coated abrasive offers twofold benefits. As the mineral is not protruding, the abrasive delivers a finer and softer finishes, grade for grade. Additionally, the slurry coating can take the place of compounds and lubricants, minimizing mess. Instead, this belt can be run with water to keep both the abrasive and the workpiece cool. Aluminum oxide mineral on the 971X gives it the ability to cut fast and finish fine. Popular among industrial professionals, aluminum oxide is a versatile synthetic mineral that can be used on a variety of substrates in both woodworking and metalworking.A Polished Touch3M understands that every application – from initial deburring to final polishing – is integral to your work.
