XYT™ Diamond Lapping Film – 9" × 11" Sheet

Name: XYT™ Diamond Lapping Film – 9" × 11" Sheet
SKU: 0

Product Overview

The XYT™ Diamond Lapping Film is a high-performance abrasive film specifically engineered for polishing the end-face of fiber optic connectors.
It enables precise shaping of fiber geometries, including restoring or forming the Radius of Curvature (RoC) and Apex Offset of the ferrule.

With a longer lifespan and faster material removal than conventional films, XYT™ Diamond Lapping Film ensures efficient and consistent polishing for both manual and automated processes.

Recommended Applications

Fiber Optic Connectors: SC, LC, ST, FC, MU, MT, MTP/MPO ferrules
Metallography: Fine sample surface preparation
Precision Components: Ceramic, metal, and composite polishing
Electronics & Semiconductors: Flat lapping and edge finishing
Micro Motor & Shaft Finishing: Smooth surface generation

Key Features

Precisely shapes fiber geometries (RoC & Apex Offset)
Longer-lasting than standard diamond or oxide films
Faster material removal for quicker polishing cycles
Uniform abrasive coating on durable PET backing
Non-flocked design prevents contamination of ferrule pinholes
RoHS & REACH compliant

Applications

Fiber Optic Connector Processing: SC, LC, FC, ST, MU, MT, MPO/MTP ferrules
Flat Lapping: Metals, ceramics, glass, and other hard surfaces
Superfinishing: Achieving mirror-quality surfaces on precision components
