The mineral is coated onto a 3 mil polyester film substrate using a durable resin system, producing a consistent cut rate and predictable finish from the first use to the last. A pressure-sensitive adhesive (PSA) backing allows for fast attachment to compatible backup pads or platens. At 8 inches in diameter and weighing 0.02 pounds, each disc is sized for bench-top and machine finishing setups used by optical and mechanical finishing technicians.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for fiber optic connector finishing and roll superfinishing operations where tight surface finish tolerances are required. The aluminum oxide mineral and tight particle distribution deliver repeatable results across production runs. Available grades span 0.05 micron to 60.0 micron, allowing technicians to step through multiple finish stages using the same disc format. Typical users include precision manufacturing technicians, optical assembly shops, and surface finishing operations requiring controlled material removal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePSA backing for fast, secure attachment to flat platens and backup pads\u003c\/li\u003e\n  \u003cli\u003eTight particle distribution delivers consistent cut rate, finish, and disc life\u003c\/li\u003e\n  \u003cli\u003eHarder resin system than 261X for improved durability and cut consistency\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide mineral on 3 mil polyester film substrate\u003c\/li\u003e\n  \u003cli\u003eAvailable in grades from 0.05 to 60.0 micron\u003c\/li\u003e\n  \u003cli\u003eAvailable in disc, sheet, and roll formats\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with flat platen finishing equipment and PSA-compatible backup pads used in fiber optic finishing and roll superfinishing applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThese discs are installed by a technician operating precision lapping or finishing equipment. Before changing discs, power down all rotating equipment and allow all moving parts to come to a complete stop. Ensure the backup platen or pad surface is clean and free of debris before applying the PSA-backed disc to prevent uneven adhesion. Follow equipment manufacturer guidelines for disc seating and alignment to maintain finish consistency.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMineral\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: 3 mil polyester film\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Pressure-Sensitive Adhesive (PSA)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade Range\u003c\/strong\u003e: 0.05 to 60.0 micron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUOM\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051111501566\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: 7000044873\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346340643122,"sku":"7000044873","price":2013.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524093.jpg?v=1782077900","url":"https:\/\/voomisupply.com\/products\/3m-7000044873-abrasive-disc-8-inch-aluminum-oxide-psa","provider":"Voomi Supply","version":"1.0","type":"link"}
