It uses aluminum oxide abrasive grains resin-bonded to a 5 mil polyester film backing, delivering consistent cut and finish across the working surface. The backing features a friction grip coating that resists slipping during use. At 50 micron grit, this roll is suited for controlled stock removal and surface refinement on precision-machined components. The roll measures 4 inches wide, 150 feet long, and fits a 3 inch core. Machinists, automotive technicians, and precision grinding shops are the primary users of this product.\u003c\/p\u003e\n\u003cp\u003eThis microfinishing film roll is used in precision cylindrical finishing applications, including superfinishing and lapping operations on automotive camshafts, crankshafts, and similar turned or ground parts. The polyester film backing provides dimensional stability under tension, making it suitable for use on roll finishing machines and manual lapping setups. It is commonly found in automotive rebuilding shops, engine machine shops, and industrial production environments where tight surface finish tolerances are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive resin-bonded to a durable 5 mil polyester film backing\u003c\/li\u003e\n  \u003cli\u003e50 micron abrasive grade for controlled material removal and surface refinement\u003c\/li\u003e\n  \u003cli\u003eFriction grip coating on the backing reduces slipping during operation\u003c\/li\u003e\n  \u003cli\u003e4 inch width x 150 ft length on a 3 inch core for extended production use\u003c\/li\u003e\n  \u003cli\u003ePolyester film backing offers dimensional stability under tension\u003c\/li\u003e\n  \u003cli\u003eSuited for cylindrical superfinishing and lapping of precision engine components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in roll finishing machines and manual lapping setups requiring a 3 inch core and 4 inch wide microfinishing film.

Ensure the finishing machine is fully stopped and de-energized before loading or changing the roll. Verify that the core diameter and roll width are compatible with the machine spindle and guides before threading the film. Avoid kinking or creasing the film during loading, as damage to the backing will affect surface finish consistency.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking\u003c\/strong\u003e: 5 mil Polyester Film\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit Grade\u003c\/strong\u003e: 50 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 ft\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCore Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Feature\u003c\/strong\u003e: Friction Grip Coating\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\u003eUPC\u003c\/strong\u003e: 00051111500323\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: 7010325534\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343091040562,"sku":"7010325534","price":1149.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524096.jpg?v=1782016326","url":"https:\/\/voomisupply.com\/products\/3m-7010325534-microfinishing-film-roll-372l-50-micron","provider":"Voomi Supply","version":"1.0","type":"link"}
