3M 7000000253 Diamond Lapping Film 3.0 Micron 6x6 Sheet

Product Description

The 3M 7000000253 is a diamond lapping film sheet engineered for precision surface finishing on extremely hard materials. Precisely graded diamond abrasive particles are uniformly coated onto a dimensionally stable polyester film backing, delivering a consistent, repeatable finish with each pass. The sheet measures 6 inches x 6 inches and carries a 3.0 micron abrasive grade, making it well suited for fine finishing and polishing operations where surface geometry and finish quality are critical. Trades working with optical components, carbide tooling, ceramics, and precision mechanical parts rely on this film for controlled material removal and predictable results.

This lapping film is used in applications where conventional abrasives cannot achieve the required finish quality on hard substrates. Typical use cases include fiber optic connector polishing, precision tool conditioning, ceramic and carbide surface refinement, and final-stage lapping of hardened mechanical components. The 6 inches x 6 inches sheet format works with flat lapping plates, backing films, and hand-lapping setups common in tool rooms, optical shops, and precision maintenance environments. The 3.0 micron grade falls within the available range of 0.10 to 30.0 micron, positioning it in the fine-to-medium finishing range of the product family.

Key Features

• Precisely graded 3.0 micron diamond abrasive particles for controlled, repeatable surface finishing
• Uniform diamond coating on polyester film backing for consistent cut rate and finish
• 6 inches x 6 inches sheet size compatible with flat lapping plates and hand-lapping fixtures
• Suitable for extremely hard materials including carbide, ceramics, and hardened steel
• Part of a multi-grade system ranging from 0.10 to 30.0 micron for staged lapping sequences

Compatibility

Designed for use as a flat lapping film sheet in precision finishing applications involving hard substrates such as carbide, ceramics, optical glass, and similar materials. Verify backing plate size and lapping fixture requirements before selecting sheet quantity.

Installation Notes

This film is installed by trades and technicians performing precision surface finishing, tool conditioning, or optical component polishing. Secure the sheet flat against a lapping plate or rigid backing surface to prevent wrinkling, which can compromise finish uniformity. Follow the manufacturer guidance for lapping fluid use, pressure, and stroke pattern appropriate to the substrate and desired finish. Dispose of spent abrasive film per facility waste handling procedures.
