3M 7000044750 Diamond Lapping Film Disc 8 Inch

Product Description

The 3M 7000044750 is a diamond lapping film disc engineered for precision surface finishing on extremely hard materials. Precisely graded diamond particles are coated onto a polyester film backing, producing a consistent, repeatable finish across each use. The disc measures 8 inches in diameter and is sold individually. This product is used in applications where tight surface tolerances are required, such as finishing ceramics, carbides, optical components, and hardened metals. Installation and use is typically handled by tooling specialists, precision machinists, or trade professionals working in lapping and polishing operations.

Diamond lapping film discs in this family are suited for flat lapping, edge finishing, and surface preparation tasks where conventional abrasives fall short. The polyester film backing provides dimensional stability, helping maintain flat surface contact throughout the cut. This disc is part of a product line available in grades ranging from 0.10 to 30.0 micron, allowing users to select the appropriate cut rate and finish level for a given substrate and application requirement.

Key Features

• Precisely graded diamond particles bonded to a polyester film backing for consistent, repeatable finishes
• Fast cut rate increases throughput on hard-to-abrade materials
• Promotes flatter surfaces and sharper edges compared to conventional abrasive films
• Uniform finish across the disc surface for reliable results
• Available in multiple grades from 0.10 to 30.0 micron to match application requirements
• Available in disc, sheet, and roll formats for versatile use

Compatibility

Designed for use on extremely hard materials including ceramics, carbides, hardened metals, and optical substrates where precise surface finishing is required.

Installation Notes

This disc is intended for use on compatible lapping machines or rotary fixture setups. Ensure the lapping plate or backing surface is clean and free of debris before mounting the disc. Verify that disc rotation speed and applied pressure are within the equipment manufacturer's specified operating range. Proper personal protective equipment, including eye protection, should be worn during operation.
