The 3M Lapping Film Discs with PSA Back are engineered for precise lapping and polishing tasks where fast, secure attachment is required. Available in multiple diameters and abrasive types, these discs provide controlled material removal and consistent surface finishing across metals, glass, ceramics, and composites.
Key Features:
Sizes: 4″ x NH (102mm x NH), 5″ x NH (127mm x NH), 8″ x NH (203mm x NH), and 12″ x NH (305mm x NH)
Backing: Pressure-Sensitive Adhesive (PSA) for direct, secure attachment to lapping platens and backing plates
Abrasive Materials: Aluminum Oxide (AlOx), Silicon Carbide (SiC), and Cerium Oxide (CeO)
Micron Sizes: Available in 0.05, 0.3, 0.5, 1, 3, 5, 9, 12, and 30 microns (size- and abrasive-dependent)
Pack Quantity: 50 discs per pack (8″ and 12″); 100 discs per pack (4″ and 5″)
Benefits:
Secure, No-Slip Attachment: PSA backing bonds directly to the platen for stable performance during repeated polishing strokes
Efficient Setup: Peel-and-apply attachment eliminates the need for separate mounting hardware, reducing changeover time
Precise Material Removal: Graded abrasive particles deliver consistent, controlled cutting action for smooth, defect-free surfaces
Broad Size Range: Four diameters support applications from small-format tooling to large-area surface preparation
Reliable, Repeatable Results: Uniform abrasive coating ensures consistent finish quality across discs and production runs
Applications:
Metal Finishing: Precision grinding and polishing of steel, aluminum, and other alloys
Optical Surfaces: Glass and optical component finishing
Ceramics & Composites: Smoothing and polishing ceramic and composite materials
Tool & Die Making: Surface preparation and refinement for precision components
General Industrial: Surface preparation prior to plating, coating, or additional finishing steps
