Built on a reinforced resin system for added toughness and extended service life, this film delivers consistent cut and finish across demanding cycles. The roll measures 4 inches wide by 50 feet long and is wound on a 3-inch core, making it compatible with standard roll-polishing equipment. At a 30.0 micron grade, it is suited for intermediate lapping and superfinishing stages where controlled stock removal and repeatable surface finish are required.\u003c\/p\u003e\u003cp\u003eThis diamond lapping film is used primarily in superfinishing, roll polishing, and flat lapping applications. Typical end users include precision grinding shops, tool and die operations, optical fabricators, and industrial maintenance technicians working with hard or difficult-to-finish materials such as ceramics, carbide, and hardened steel. The 30.0 micron grade fits between coarser stock-removal stages and finer polishing steps in a multi-stage finishing sequence.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eReinforced resin bond system provides added toughness and longer film life compared to standard lapping films\u003c\/li\u003e\n\u003cli\u003e30.0 micron diamond grade delivers controlled intermediate cut for superfinishing and flat lapping\u003c\/li\u003e\n\u003cli\u003eRoll format (4 inches x 50 feet) minimizes changeover frequency on continuous or semi-continuous polishing equipment\u003c\/li\u003e\n\u003cli\u003e3-inch core fits standard roll-polishing machine mandrels\u003c\/li\u003e\n\u003cli\u003eConsistent abrasive distribution across the full roll length supports repeatable surface finish results\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use consumable for roll polishing machines, flat lapping fixtures, and superfinishing equipment that accept 4-inch wide abrasive film rolls on a 3-inch core.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eLoading and threading lapping film rolls should be performed by a qualified machine operator following the equipment manufacturer's guidelines. Power down and de-energize the polishing machine before loading a new roll. Ensure the film path is free of debris and that tension settings are appropriate for the film thickness to avoid tearing or uneven wear. Consult the equipment manufacturer's documentation for feed rate and pressure recommendations specific to diamond lapping films.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMicron Grade\u003c\/strong\u003e: 30.0 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: 50 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore Diameter\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\u003eWeight\u003c\/strong\u003e: 1.8 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051111499733\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: 7000044834\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344147317042,"sku":"7000044834","price":2142.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524124.jpg?v=1782030283","url":"https:\/\/voomisupply.com\/products\/3m-7000044834-diamond-lapping-film-30-0-micron-roll","provider":"Voomi Supply","version":"1.0","type":"link"}
