Description

Our 3M™ microfinishing film roll 372L features micron graded premium aluminum oxide bonded to a 5 mil 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. In order to achieve an extremely consistent scratch for microfinishing, we use micron graded mineral, measured at a very tight size tolerances for 3M™ microfinishing film roll 372L. The resin bond ensures reliable, consistent performance. With a durable film backing, the abrasive helps achieve tight geometry and finish tolerances. This microfinishing roll comes in a broad range of micron grades to achieve reproducible surface characteristics and geometric values that adhere to specification. In some applications, numerous grades are run simultaneously to achieve finishes that differ across the surface of a single complex part. To reduce risk of operator error, we designed type 2 film in a range of colors - reflective of each grade. The color coding is a useful visual cue, as is sorting width by core size and side and end of roll printing and marking.
