3M 7010359526 Diamond Lapping Film Disc 12 in Psa

Product Description

The 3M 7010359526 is a 12-inch diameter, PSA-backed diamond lapping film disc designed for precision surface finishing on extremely hard materials. Built on the 668X platform, it features precisely graded diamond abrasive particles coated onto a polyester film substrate. The pressure-sensitive adhesive (PSA) backing allows fast, secure disc changes on compatible lapping machines. It accepts a 1 1/4-inch arbor and is suited for applications requiring a consistent, repeatable finish with minimal edge rounding. The diamond abrasive delivers fast cut rates and extended service life, reducing the frequency of abrasive changes during production runs.

This disc is used in precision grinding, lapping, and polishing operations across industries such as fiber optics, advanced ceramics, carbide tooling, and semiconductor component finishing. It is designed for flat surface work where geometry control and surface uniformity are critical. The PSA construction makes it compatible with rotary lapping equipment using a flat platen. Machinists, tool grinders, and precision finishing technicians are the primary installers and users of this product. Available grades in the 668X series range from 0.10 micron to 30.0 micron, supporting both rough lapping and final polishing stages.

Key Features

• PSA backing for quick, secure attachment to flat lapping platens
• Precisely graded diamond particles for consistent, repeatable surface finish
• Fast cut rate increases throughput on hard materials
• Flat surface geometry with low edge rounding
• Long abrasive life reduces disc change frequency
• Available in grades from 0.10 to 30.0 micron

Compatibility

Designed as an OEM-style replacement or standard consumable for rotary lapping machines equipped with a flat platen and 1 1/4-inch arbor accepting 12-inch diameter PSA-backed discs.

Installation Notes

Installation is performed by precision finishing technicians or machine operators. Power down and de-energize the lapping machine before changing discs. Clean the platen surface thoroughly before applying the PSA disc to ensure full adhesion and avoid surface irregularities during operation. Follow the equipment manufacturer's guidelines for disc seating and rotational speed limits.
