Brand 3M™ Global Product Hierarchy Film Sheets & Rolls Base (B) - Article Number 00638060667507 Unit of Use (1) - Article Number 00638060667507 Marketplace Formal Name 3M™ Microfinishing Film Roll, 372L, 40 micron, 1 in x 900 ft x 3 in (25.4 mm x 274.3 m x 76.2 mm) Material Description 372L 40MIC 1 X 900FT X 3 SP ASO ERM RL Marketplace Description The 3M™ Microfinishing Film Roll 372L features micron-graded premium aluminum oxide bonded to a 5 mil (0.13 mm) polyester film backing to deliver uniform results and meet stringent surface requirements. A friction grip coating provides slip resistance for microfinishing machines where film slippage is an issue, and close tolerance work on cylindrical surfaces, such as automotive camshafts and crankshafts. Marketplace Description Extended In order to achieve a consistent scratch for microfinishing, the 3M™ Microfinishing Film Roll 372L features micron-graded mineral, measured at very tight size tolerances. This roll's resin bond ensures reliable, consistent performance. With a durable film backing, the abrasive can navigate tight geometry and finish tolerances. This microfinishing roll comes in a broad range of micron grades to achieve a consistent finish without altering part geometry. To reduce risk of operator error, Type 2 film was designed in a range of colours, reflective of each grade. The colour coding is a useful visual cue, as is sorting width by core size and side and end of roll printing and marking. Film backings provide a superior, uniformly flat surface to hold abrasive particles – abrasive grains don’t compress or become pressed into the backing. Highly conformable and tear-resistant, this roll's polyester film backing flexes to help achieve a consistent finish over contours and is stronger than other 3M™ Abrasives, making it ideal for high-production environments. Manufacturers of critical automotive components have little room for error in producing parts to specification. Engine component surfaces and geometry can be improved by using microfinishing which removes variations on the surface, minimizes friction, and manipulates metal behaviour in other ways.
