It features aluminum oxide mineral uniformly coated onto a 3 mil polyester film backing using a durable resin bond system. The film measures 4 inches wide by 150 feet long and fits a 3-inch core. At 40.0 micron grade, this roll delivers consistent scratch patterns suited to intermediate finishing steps where dimensional accuracy and surface uniformity are critical. Technicians and finishing specialists rely on this product where repeatable, grade-specific abrasion is required.\u003c\/p\u003e\n\u003cp\u003eThis lapping film is commonly used in fiber optic connector end-face finishing and roll superfinishing operations. Fiber optic technicians use it during polishing sequences to prepare ferrule end faces to low-reflectance specifications. It also sees use in precision roll finishing environments where tight surface finish tolerances are maintained on cylindrical components. The roll format supports both manual and machine-driven finishing setups, making it adaptable across bench and production-line contexts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide mineral provides consistent, controlled cut rate at 40.0 micron grade\u003c\/li\u003e\n  \u003cli\u003e3 mil polyester film backing resists tearing and conforms to precision finishing fixtures\u003c\/li\u003e\n  \u003cli\u003eDurable resin bond system maintains mineral adhesion through extended finishing cycles\u003c\/li\u003e\n  \u003cli\u003eRoll format supports continuous feed in automated or semi-automated finishing equipment\u003c\/li\u003e\n  \u003cli\u003eAvailable across 7 grades from 0.05 to 60.0 micron for multi-step finishing sequences\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in fiber optic finishing polishing sequences and roll superfinishing operations requiring a 40.0 micron aluminum oxide lapping film on a 3-inch core roll.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis product is handled and installed by fiber optic technicians, precision grinding specialists, or equipment maintenance personnel. Before loading film onto polishing or lapping equipment, ensure the machine is powered down and all rotating components have come to a full stop. Secure the roll onto the core mandrel per equipment manufacturer guidelines and verify film tension settings before resuming operation. Avoid contact between the abrasive surface and any unintended workpiece or fixture to prevent premature wear or surface contamination.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMineral Type\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilm Backing Thickness\u003c\/strong\u003e: 3 mil polyester\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: 40.0 micron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoll Width\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoll Length\u003c\/strong\u003e: 150 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCore Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Roll\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.95 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051111496954\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000027557\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346078236978,"sku":"7000027557","price":1169.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310523968.jpg?v=1782070724","url":"https:\/\/voomisupply.com\/products\/3m-7000027557-lapping-film-roll-40-0-micron-4x150ft","provider":"Voomi Supply","version":"1.0","type":"link"}
