3M microfinishing film belt 472L was designed for superfinishing and powertrain microfinishing. This belt helps achieve uniform, consistent finishes on parts where close tolerances are important.
Built for Microfinishing- The 3M microfinishing film belt 472L is designed to deliver uniform, consistent finishes on parts where a close tolerance finish is essential. Micron-graded silicon carbide mineral is ideal for finishing of metals, plastics, wood and various other substrates.
- On flat parts, like die castings, and cylindrical or contoured workpieces such as auto parts-consistent and predictable finishes are key. 3M microfinishing film belt 472L helps produce fine finishes and achieve close tolerances by way of a durable, uniform film backing and micron-graded mineral. Recommended applications are finishing on metals, plastic, wood and various other substrates.
- 3M microfinishing film belt 472L is made by adhering micron-graded silicon carbide mineral to polyester film using a resin bond. Silicon carbide mineral is very hard and fractures easily, resulting in freshly exposed sharp edges that cut fast and produce a bright looking finish. While it wears faster than aluminum oxide, it produces a brighter finish. Belt 472L is available in a variety of grades, so operators can tailor the grade to their part.
- The high-strength 5 mil polyester backing won't yield or deflect when run, which is helpful when close tolerances are important. With a uniform backing the abrasive maintains consistent contact with the workpiece to maintain critical geometries.
- Across industries, from transportation to heavy equipment, from general industrial to aerospace, professionals value part integrity and consistency. Combining the strength of a polyester film backing with the aggressive cutting qualities of micron-graded silicon carbide, 3M microfinishing film belt 472L is a good match for workpieces that require precise and uniform cutting action.
Features:
- Micron-graded silicon carbide mineral cuts sharp and fast while producing extremely consistent, fine finishes
- High-strength 5 mil polyester backing won't yield or deflect when run, contributing to aggressive cut
- May be used on metal, plastic, wood and various other substrates
- Open coat construction reduces loading to maintain consistent, sharp cut and extend disc life for greater productivity
