Lapping film in sheets
Discs suit rotary polishing machines. Sheets offer more freedom: you lay them on a surface plate or flat platen for hand lapping, cut them to the dimensions of a template, or mount them on a dedicated tool.
Why a lapping film
A conventional abrasive has grains of somewhat scattered sizes: a few larger grains leave isolated scratches, invisible in ordinary sanding, unacceptable in precision finishing. Lapping film uses grains sorted to a tight tolerance, spread in an even layer on a perfectly flat film. The scratch is uniform and the finish repeatable.
Applications
Lapping flat faces and seal faces, finishing metrology parts, sharpening and finishing tools, polishing glass or ceramic components, sample preparation.
Application
Lay the sheet on a flat, clean surface: any dust underneath becomes a high spot. Work with a suitable lubricant, with regular strokes, and clean part and workstation between two grades.
