Built on the 668X platform, this disc features precisely graded diamond particles coated on a durable polyester film substrate. The pressure-sensitive adhesive backing allows secure, repeatable mounting on flat lapping fixtures. Available in grades ranging from 0.10 to 30.0 micron, this disc delivers a consistent, uniform finish with fast material removal rates and minimal edge rounding. It is used by precision machinists, optical technicians, and tool-and-die professionals who require tight surface finish tolerances.\u003c\/p\u003e\n\u003cp\u003eThis lapping film disc is suited for flat lapping and polishing of hard substrates including carbide, ceramics, hardened steel, and optical components. The PSA backing simplifies disc changes and maintains consistent contact across the full 8-inch working surface. Its long abrasive life reduces the frequency of disc changes, supporting higher throughput in production and repair environments. The disc format is appropriate for use on rotary lapping machines and flat-lap stations common in precision manufacturing and metrology shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePSA backing for secure, tool-free mounting and fast disc changes\u003c\/li\u003e\n  \u003cli\u003ePrecisely graded diamond abrasive particles for consistent, repeatable finish quality\u003c\/li\u003e\n  \u003cli\u003eAvailable in micron grades from 0.10 to 30.0 micron to match finishing stage requirements\u003c\/li\u003e\n  \u003cli\u003eFlat surface geometry with low edge rounding for accurate workpiece profiles\u003c\/li\u003e\n  \u003cli\u003eLong abrasive service life reduces downtime from frequent disc replacement\u003c\/li\u003e\n  \u003cli\u003ePolyester film backing provides dimensional stability during lapping operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on rotary flat-lap machines and lapping stations that accept 8-inch PSA-backed abrasive discs.

Ensure the platen surface is clean and free of debris before applying the PSA disc to prevent uneven contact or premature delamination. Power down the lapping machine before mounting or removing the disc. Follow the machine manufacturer guidelines for platen speed and applied load appropriate to the selected micron grade.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Type\u003c\/strong\u003e: PSA (Pressure-Sensitive Adhesive)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilm Substrate\u003c\/strong\u003e: Polyester\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Grade Range\u003c\/strong\u003e: 0.10 to 30.0 micron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 25\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: 7000044837\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344952066354,"sku":"7000044837","price":940.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310524082.jpg?v=1782046632","url":"https:\/\/voomisupply.com\/products\/3m-7000044837-diamond-lapping-film-disc-8-inch-psa","provider":"Voomi Supply","version":"1.0","type":"link"}
