3M 7010328319 Diamond Lapping Film Disc 5 Inch

Product Description

The 3M 7010328319 is a 5-inch diameter diamond lapping film disc engineered for precision abrasive finishing and material removal applications. Built on the 662XW platform, this disc features a higher diamond concentration and a stronger resin bond compared to standard diamond lapping film, resulting in increased durability and a faster cut rate. The polyester-backed construction maintains a flat working surface, preventing edge rounding and producing consistent finish quality across the workpiece. This disc is suited for use in fiber optic connector polishing, precision optics, ceramics, and similar fine-tolerance finishing tasks performed by skilled technicians and trade professionals.

This disc is designed for use in controlled precision finishing environments where consistent material removal and surface flatness are critical. The 662XW construction is available in multiple micron grades including 0.50, 1.0, 1.50, 3.0, 6.0, and 9.0 micron, allowing technicians to select the appropriate grit for each stage of a progressive lapping sequence. The 5-inch diameter format is compatible with standard rotary lapping fixtures and polishing machines used in fiber optic, optical component, and precision mechanical finishing workflows.

Key Features

• Higher diamond concentration delivers increased cut rate over standard diamond lapping film
• Stronger resin bond provides added durability and extended abrasive life, reducing disc change frequency
• Flat surface geometry prevents edge rounding and maintains workpiece geometry throughout the lapping process
• Available in 0.50, 1.0, 1.50, 3.0, 6.0, and 9.0 micron grades for multi-stage finishing sequences
• 5-inch diameter format fits standard rotary lapping and polishing equipment
• Available in disc, roll, and sheet formats to suit different application setups

Compatibility

Designed for use with standard 5-inch rotary lapping fixtures and polishing machines in precision finishing applications including fiber optic connector polishing, optical components, and fine-tolerance ceramic or mechanical part finishing.

Installation Notes

This disc is installed and used by precision finishing technicians and skilled trade professionals operating rotary lapping or polishing equipment. Ensure the backing plate or fixture is clean and flat before mounting the disc to avoid surface irregularities during use. Follow equipment manufacturer guidelines for rotational speed and applied pressure appropriate to the micron grade in use. Dispose of worn discs according to local regulations for abrasive materials.
