3M 7010359517 Diamond Lapping Film Disc 8 Inch Psa

Product Description

The 3M 7010359517 is an 8-inch diameter PSA-backed diamond lapping film disc designed for precision flat lapping applications. Built on the 664X platform, this disc uses a stronger resin system compared to the 663X series, resulting in added toughness and extended abrasive life. The pressure-sensitive adhesive backing allows fast, repeatable mounting to lapping plates and fixtures. It delivers a fast cut rate while maintaining a uniform finish and minimizing edge rounding on workpieces. This disc is handled and installed by machinists, tool-and-die technicians, and precision grinding specialists working in optical, semiconductor, and industrial component finishing environments.

This diamond lapping film disc is suited for flat lapping of hard materials where tight surface finish tolerances are required. The 664X formulation is available in 30.0, 45.0, and 60.0 micron grades, making it adaptable across roughing and finishing stages of a lapping sequence. Its PSA backing is compatible with standard flat lapping plates and fixtures used in production and bench-top settings. Longer abrasive life reduces the frequency of disc changes, supporting consistent throughput in high-volume operations.

Key Features

• PSA backing for fast, secure mounting to lapping plates and fixtures
• Stronger resin system versus 663X for increased toughness and durability
• Fast cut rate reduces cycle time in flat lapping operations
• Flat surface geometry minimizes edge rounding on precision workpieces
• Uniform finish across the full disc face
• Extended abrasive life reduces disc change frequency in production use

Compatibility

Designed for use in flat lapping applications with standard PSA-compatible lapping plates and fixtures. Available in 30.0, 45.0, and 60.0 micron grades; also available in rolls, discs, and sheets.

Installation Notes

Clean and dry the lapping plate surface before applying the PSA disc to ensure full adhesive contact and prevent slippage during use. Align the disc carefully before pressing down, as the PSA backing bonds on contact. Handle diamond abrasive discs with clean gloves to avoid contaminating the abrasive surface. Follow the equipment manufacturer and facility safety guidelines for abrasive tooling changeover.
