Lapping Film: Types, Applications, and Characteristics

Lapping film is a material used for precision machining and polishing, widely applied in surface treatment of various hard materials. Below, we detail its types, applications, and features.

Types and Structure

XYT™ Diamond Lapping Film

• Composition: Made of tightly graded diamond minerals micro-replicated and coated onto a polyester film backing.
• Features: Longest lifespan, superior surface finish, reduced overall process time, increased yield, slurry-free, and consistent results.
• Applications: Fiber optic connector processing, glass and ceramic grinding.

XYT™ Diamond Lapping Films Microfinishing Series

• Composition: Similarly, these films feature tightly graded diamond minerals uniformly coated onto a polyester film backing.
• Features: Excellent surface finish and longevity, with or without pressure-sensitive adhesive (PSA) backing options.
• Applications: Fiber optic connector polishing, flat lapping, and ultra-fine polishing.

Other Models

• XYT™ Diamond Lapping Film Superfinishing: Launched in 2023, it combines high cutting rates with superior surface finish, suitable for low-speed polishing machines.
• XYT™ Diamond Lapping Film Precision Polishing: Designed for single-side flat lapping, it utilizes a thicker diamond coating and higher diamond concentration.

Features and Advantages

• Consistency and Repeatability: These lapping films provide repeatable and precise surface treatment, particularly in applications requiring strict tolerances.
• Slurry-Free Process: Using water-based coolants instead of traditional lapping slurries reduces contamination and enhances cleanliness.
• Versatility: Suitable for various applications and machines, including CNC/robotic polishing.
• Durability: For example, XYT™ Diamond Lapping Film Microfinishing and Superfinishing offer more uniform visual appearance and long-lasting results.

Application Fields

• Electronic Components: Used for fine machining and polishing to meet high precision requirements.
• Fiber Optic Connectors: Employed for polishing and final polishing of fiber optic connectors.
• Hard Materials: Suitable for ceramics, glass, quartz, silicon carbide, etc.

Storage and Shelf Life

• Storage Conditions: Recommended storage temperature is 50-90°F with 30-70% relative humidity. It is advised to use the films within 24 months of purchase.

In summary, lapping films are efficient and versatile materials for surface treatment of various hard materials. Their unique structural design and superior performance make them widely used in precision machining and polishing fields.
