The abrasive mineral is coated onto a 3 mil polyester film substrate and bonded with a durable resin system that outperforms softer resin formulations in cut consistency and disc life. A pressure-sensitive adhesive (PSA) backing allows fast, repeatable mounting to compatible backup pads and platens. Available in seven grades ranging from 0.05 to 60.0 micron, this disc serves technicians and process engineers who need tight control over surface finish quality across a range of material removal rates.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for fiber optic connector end-face finishing and roll superfinishing operations where precise, consistent stock removal is required. The tight particle size distribution ensures uniform scratch patterns and predictable finish results across the full disc life. It is used in both production and bench-top finishing setups where a PSA-backed disc format is preferred over pressure-plate or film-frame alternatives. Operators in telecommunications component manufacturing, precision machining, and optical fabrication shops are the primary users of this product.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePSA backing for fast, secure mounting and removal from compatible platens\u003c\/li\u003e\n  \u003cli\u003eTight particle size distribution for consistent scratch pattern and finish uniformity\u003c\/li\u003e\n  \u003cli\u003eHarder resin system delivers longer disc life and more consistent cut rate compared to softer resin alternatives\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide mineral on 3 mil polyester film substrate for dimensional stability\u003c\/li\u003e\n  \u003cli\u003eAvailable in seven micron grades from 0.05 to 60.0 micron to match varied finishing requirements\u003c\/li\u003e\n  \u003cli\u003eCompatible disc format also available in sheets and rolls for alternate fixturing setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in fiber optic finishing and roll superfinishing applications requiring a 12-inch PSA-backed lapping disc on standard platen or backup pad equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by technicians or process engineers operating lapping or polishing equipment. Before mounting, ensure the platen or backup pad surface is clean and free of debris that could cause uneven disc adhesion or premature delamination. Align the disc concentrically on the platen before pressing to seat the PSA bond fully. Follow equipment manufacturer lockout procedures before changing discs on powered lapping machines.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 12 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 (7 grades available)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 00051111497852\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: 7000044822\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347090768178,"sku":"7000044822","price":1318.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524037.jpg?v=1782097400","url":"https:\/\/voomisupply.com\/products\/3m-7000044822-aluminum-oxide-lapping-disc-12-inch-psa","provider":"Voomi Supply","version":"1.0","type":"link"}
