3M™Microfinishing Film Roll 279L, YF10 45700-101.6-A15µ-WF1001R5-3"PL4S-ASO

Designed for Fine Finishing 3M™ Microfinishing Film Roll 279L is designed for a variety of common microfinishing applications, from cylindrical and centerless grinding and finishing to roll finefinishing. It’s also a great match for automotive powertrain components, which tend to require a flexible abrasive that can get into hard-to-reach spaces. As a roll, 279L has great flexibility in terms of its form. The roll can be cut and shaped to meet the dimensions of your part or project and may be used by hand or with microfinishing machines. We engineer 3M™ Microfinishing Film Roll 279L by anchoring aluminum oxide mineral to a polyester film backing with resin. We chose aluminum oxide finer mineral for this abrasive, because it is a popular choice among industrial professionals who favor the fast cut rate and long life. Aluminum oxide’s hardness, strength and low heat retention help the roll withstand wear and tear. Features a Water-Resistant Polyester Backing 3M™ Microfinishing Film Roll 279L features a 5 mil polyester backing. In general, film backed abrasives are known for their flexibility, incompressibility and caliper consistency– it’s what makes them a great match for microfinishing operations. The anti-slip or friction coating on the back of the roll aides in preventing slippage during the microfinishing application, which is critical to consistency from part to part. Made with polyester, 3M™ Microfinishing Film Roll 279L is water resistant and can be run wet or dry. Applying a lubricant like water may help with washing away unwanted swarf and debris, which can clog the roll and cause the mineral to dull prematurely. On dust-generating substrates, using a lubricant can come in handy. Available in a Range of Grades Given that it’s available in a versatile range of grades – from 5 to 40 micron – operators can select the right grade for their application. Lower grades, like 5-40 micron, are good for softer, finer finishes. Grades are color-coded to reduce the risk for error when there are multiple grades in a sequence. The Benefits of 3M Microfinishing Abrasives Altogether, 3M™ Microfinishing Film Roll 279L enables you to quickly remove traverse marks and feed lines, eliminate chatter, follow existing geometry and achieve desired RA (roughness average).These are some of the reasons why this roll and other 3M microfinishing abrasives are used across industries

• Micron-graded Aluminum oxide grain
• Durable 5 mil Polyester film (PET) backing
• Electrostatically oriented coating
