3M 7000045616 Aluminum Oxide Lapping Film Disc 8 in

Product Description

The 3M 7000045616 is an 8-inch diameter aluminum oxide lapping film disc designed for precision surface finishing across a wide range of substrates. Precisely graded aluminum oxide abrasive particles are coated onto a 3-mil polyester film backing, producing a tight particle size distribution that delivers consistent cut rate, finish quality, and disc life throughout the working cycle. This disc is part of 3M's standard lapping film line, available in micron grades of 0.30, 3.0, 5.0, 9.0, 12.0, and 30.0. It is used by machinists, optical technicians, fiber optic technicians, and precision finishing specialists who require repeatable, uniform surface finishes.

This lapping film disc is suited for precision lapping and polishing applications in manufacturing, fiber optic connector preparation, optical component finishing, and similar precision trades. The polyester film backing provides dimensional stability during use, helping maintain consistent contact across the workpiece surface. It is sold individually and is compatible with standard lapping plate setups and backing fixtures used in precision finishing workflows.

Key Features

• Aluminum oxide abrasive on a 3-mil polyester film backing for dimensional stability
• Tight particle size distribution ensures consistent cut rate and surface finish
• 8-inch diameter format fits standard lapping plate and fixture setups
• Available in six micron grades: 0.30, 3.0, 5.0, 9.0, 12.0, and 30.0 micron
• Produces uniform finishes across a variety of substrate materials

Compatibility

Designed for use with standard lapping plates and backing fixtures that accept 8-inch diameter abrasive film discs in precision finishing and polishing applications.

Installation Notes

Lapping film discs are installed by precision finishing technicians on lapping plates or backing fixtures appropriate for the application. Ensure the lapping plate surface is clean and free of debris before mounting the disc to avoid uneven abrasive contact. Follow the equipment manufacturer's guidance for disc mounting, applied pressure, and rotation speed to achieve the intended surface finish grade.
