Aluminum oxide abrasive grain is resin bonded to a 5 mil polyester film backing, delivering consistent cut and finish control across the full roll length. The backing incorporates a friction grip coating that reduces slip during operation, keeping the film stable against the workpiece. At 30 micron grade, this roll is suited for fine-finishing stages where tight surface tolerances are required. It is sized at 8 inches wide by 150 feet long with a 3-inch keyed core and weighs 7 pounds.\u003c\/p\u003e\u003cp\u003eThis microfinishing film roll is used in precision cylindrical grinding and finishing operations, most commonly in automotive and industrial machine shops. Typical applications include finishing camshafts, crankshafts, and similar round or journal surfaces where surface finish consistency directly affects part performance. The keyed core design is compatible with film finishing equipment that accepts a 3-inch keyed spindle. It is sold in roll form and intended for professional machine operators and finishing technicians working with lapping film equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e30 micron aluminum oxide abrasive for fine, controlled material removal\u003c\/li\u003e\n\u003cli\u003eResin bonded grain on a 5 mil polyester film backing for dimensional stability\u003c\/li\u003e\n\u003cli\u003eFriction grip backing coating reduces slippage during use\u003c\/li\u003e\n\u003cli\u003eKeyed 3-inch core for secure mounting on compatible film finishing equipment\u003c\/li\u003e\n\u003cli\u003e150-foot roll length minimizes changeover frequency in production environments\u003c\/li\u003e\n\u003cli\u003eDesigned for precision cylindrical surface finishing including camshafts and crankshafts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with film finishing equipment that accepts an 8-inch wide roll on a 3-inch keyed core spindle.

Ensure the machine is fully powered down and all rotating components have stopped before loading or changing the roll. Verify the keyed core seats securely on the spindle before resuming operation. Follow the equipment manufacturer guidelines for feed rate, contact pressure, and coolant use to avoid film distortion or premature wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMicron Grade\u003c\/strong\u003e: 30 Micron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking\u003c\/strong\u003e: 5 mil Polyester Film\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Coating\u003c\/strong\u003e: Friction Grip\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 150 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore Size\u003c\/strong\u003e: 3 inches Keyed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Roll\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051144801381\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 7000028106\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347968360754,"sku":"7000028106","price":570.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310534671.jpg?v=1782116880","url":"https:\/\/voomisupply.com\/products\/3m-7000028106-microfinishing-film-roll-30-micron-8x150ft","provider":"Voomi Supply","version":"1.0","type":"link"}
