3M 7000044738 Lapping Film 0.02 Micron Sheet 6x6 in

Product Description

The 3M 7000044738 is a precision lapping film sheet designed for the final polishing step in fiber optic ceramic connector finishing. It features a silica mineral abrasive coating applied to a 3 mil polyester backing. The 0.02 micron abrasive grade delivers the ultra-fine surface finish required at the last stage of connector end-face polishing. Each sheet measures 6 inches x 6 inches. The film is compatible with a wide range of polishing machines and is particularly well suited for slower-speed machines and manual polishing workflows. Fiber optic technicians and precision assembly professionals are the primary users of this consumable.

This lapping film is used in fiber optic termination and connector polishing applications across telecommunications, data center, and industrial fiber network installations. It performs as a final-step consumable after coarser abrasive grades have been used to shape and refine the connector end-face. Its compatibility with multiple polishing machine brands makes it practical for shops and field technicians running varied equipment. Manual polishing setups benefit from its performance at lower surface speeds.

Key Features

• 0.02 micron silica mineral abrasive for ultra-fine final-step polishing
• 3 mil polyester backing provides consistent film support and flatness
• 6 inches x 6 inches sheet size fits common polishing fixtures
• Compatible with many brands of fiber optic polishing machines
• Preferred for slower machines and manual polishing processes
• Designed specifically for ceramic fiber optic connector end-face finishing

Compatibility

Designed for use on many different brands of fiber optic polishing machines and suitable for manual processing applications requiring a 6 inches x 6 inches lapping film sheet at the 0.02 micron final polishing stage.

Installation Notes

This consumable is installed by placing the sheet onto the polishing plate or fixture of the polishing machine per the equipment manufacturer's instructions. Ensure the polishing surface and film are free of debris before use, as contamination at this final stage can compromise connector end-face quality. No special tools are required, but clean handling practices are essential when working at sub-micron abrasive grades. Follow applicable industry standards such as IEC 61300-3-35 for end-face geometry inspection after polishing.
