3M 7000044852 Diamond Lapping Film 30.0 Micron Sheet

Product Description

The 3M 7000044852 is a diamond lapping film sheet designed for precision surface finishing of extremely hard materials. Precisely graded diamond abrasive particles are coated on a dimensionally stable polyester film backing, delivering a consistent, repeatable finish with each pass. At 30.0 micron grade, this sheet is suited for stock removal and initial surface conditioning stages in a lapping sequence. Each sheet measures 9 inches x 11 inches and is sold in a minimum quantity of 10 sheets per order. Machinists, optical technicians, toolmakers, and precision maintenance professionals use this product where tight surface finish tolerances are required.

Diamond lapping film in the 30.0 micron grade is commonly used in the early stages of a multi-step lapping or polishing progression on carbide tooling, ceramic components, optical fibers, glass, and other hard substrates. It is used in both production and maintenance settings where conventional abrasive films lack the cutting ability or consistency required. The flat, flexible sheet format allows use on lapping plates, backing pads, or flat glass reference surfaces depending on the application.

Key Features

• 30.0 micron precisely graded diamond abrasive for controlled, repeatable stock removal
• Diamond particles coated on a dimensionally stable polyester film backing
• 9 inches x 11 inches sheet size for use on standard lapping plates and backing surfaces
• Suitable for extremely hard materials including carbide, ceramic, and optical glass
• Part of a multi-grade lapping film series ranging from 0.10 to 30.0 micron

Compatibility

Designed for use as a lapping and polishing film on hard substrates such as carbide, ceramic, glass, and optical fiber end-faces where conventional abrasives are insufficient.

Installation Notes

Diamond lapping film is typically installed by precision machinists, optical technicians, or toolroom professionals. Secure the sheet flat against a lapping plate, backing pad, or flat reference surface before use to prevent wrinkling or uneven abrasion. Use appropriate personal protective equipment when handling abrasive films and follow any facility-specific procedures for abrasive material handling and disposal. Progress through finer micron grades in sequence to achieve the target surface finish.
