3M 7000045615 Aluminum Oxide Lapping Film Disc 8 in

Product Description

The 3M 7000045615 is an 8-inch diameter aluminum oxide lapping film disc built for precision surface finishing across a range of substrates. Precisely graded aluminum oxide particles are coated onto a 3-mil polyester film backing, delivering tight particle size distribution and a consistent cut rate from disc to disc. The result is a uniform, repeatable finish critical in applications where surface quality directly affects component performance. This disc is part of 3M's standard lapping film line, available in 0.30, 3.0, 5.0, 9.0, 12.0, and 30.0 micron grades to cover a wide range of finishing requirements.

This lapping film disc is used in precision finishing operations across industrial, optical, fiber optic connector, and mechanical component applications. It is well-suited for finishing metals, ceramics, glass, and composite substrates where controlled material removal and a uniform surface are required. Machinists, optical technicians, and skilled tradespeople performing precision lapping and polishing tasks will find this disc appropriate for both manual and machine-assisted finishing setups.

Key Features

• Tight aluminum oxide particle distribution ensures consistent finish quality across the disc surface
• Consistent cut rate, finish quality, and disc life reduce rework and material waste
• 3-mil polyester film backing provides dimensional stability during use
• 8-inch diameter format suits standard lapping plates and disc-based finishing equipment
• Available in multiple micron grades from 0.30 to 30.0 for rough through ultra-fine finishing

Compatibility

Designed for use as a precision lapping and polishing disc compatible with standard 8-inch lapping plates and disc finishing equipment used in industrial and optical surface preparation applications.

Installation Notes

Lapping film discs are typically installed and used by machinists or precision finishing technicians. Ensure the lapping plate surface is clean and free of debris before applying the disc. Select the appropriate micron grade for the required surface finish and work from coarser to finer grades in a controlled sequence. Follow the equipment manufacturer's guidelines for disc attachment and pressure settings.
