3M 7000028119 Diamond Lapping Film Disc 5 Inch 662XW

Product Description

The 3M 7000028119 is a 5-inch diamond lapping film disc from the 662XW series, engineered for precision abrasive finishing applications. It features a higher diamond concentration and a stronger resin bond compared to standard diamond lapping film, delivering increased cut rate and greater durability over the life of the disc. This disc is used in optical, fiber optic connector, aerospace component, and precision surface finishing applications where flat, consistent stock removal is required. Installation and use are handled by skilled technicians and machinists working in high-tolerance finishing environments.

The 662XW disc is suited for applications that demand a flat, uniform surface without edge rounding. The extended abrasive life reduces the frequency of disc changes, supporting higher throughput on production lapping fixtures and precision grinding setups. This product is available in multiple grades and formats, making it adaptable across different stages of a lapping or polishing sequence.

Key Features

• Higher diamond concentration for increased cut rate over standard diamond lapping film
• Stronger resin bond provides added durability and extended disc life
• Maintains flat surface contact with no rounding of workpiece edges
• Long abrasive life minimizes disc change intervals and improves throughput
• Available in 0.50, 1.0, 1.50, 3.0, 6.0, and 9.0 micron grades
• Also available in rolls and sheets for alternate fixture configurations

Compatibility

Designed for use with 5-inch lapping fixtures and precision surface finishing systems that accept standard film-backed abrasive discs.

Installation Notes

This disc is typically mounted and used by skilled machinists or precision finishing technicians on lapping machines or hand-held fixtures. Ensure the lapping plate or fixture surface is clean and free of debris before applying the disc to avoid uneven contact. Follow equipment manufacturer guidelines for disc attachment and applied load to maintain consistent surface flatness and avoid premature wear.
