Diamond Lapping Film Discs are engineered for ultra-precise surface finishing, delivering exceptional flatness and smoothness for demanding applications in industries such as electronics, optics, materials science, and advanced manufacturing. These discs combine premium diamond abrasives with durable polyester film, offering unmatched performance on hard, brittle, or delicate materials.
Key Features
Premium Diamond Abrasives
-
Uniform Particle Distribution: Resin-bonded, graded diamond particles (0.1–30µm grit) ensure consistent material removal and scratch-free finishes.
-
Durability: Long lifespan compared to traditional abrasives like aluminum oxide or silicon carbide.
Versatile Backing Options
-
Pressure-Sensitive Adhesive (PSA): Easy mounting on metal backing plates for stability during machine use.
-
Plain Backing: Flexible for handheld or freestanding applications.
Wet/Dry Compatibility
-
Optimized for both wet (coolant-assisted) and dry workflows, reducing heat and enhancing finish quality.
Material Versatility
-
Effective on carbides, ceramics, fiber optics, wafers, microelectronics, high-hardness metals, and composites.
Applications
Scientific Research
-
TEM (Transmission Electron Microscopy): Precision polishing of thin samples for atomic-scale imaging.
-
FIB (Focused Ion Beam): Sample thinning and cross-sectioning for nanoscale analysis.
-
Metallography: Preparing polished cross-sections of metals/alloys for microstructure analysis.
Industrial Manufacturing
-
Backside Polishing: Flatness-critical processes for semiconductor wafers and optical components.
-
Advanced Composites: Finishing aerospace or automotive materials without delamination.
Specialized Tasks
-
Petrographic Samples: Preparing geological slices for microscopy.
-
Brittle Substrates: Handling fragile materials like glass or ceramics with minimal chipping.
Technical Advantages
-
Edge Retention & Coplanarity: Maintains integrity across mixed-hardness materials, ideal for multi-layer samples.
-
Custom Sizing: Tailored dimensions available for unique equipment or workflows.
-
Adhesive Flexibility: PSA backing simplifies integration into automated systems, while plain backing suits manual precision work.
Comparison to Alternatives
| Feature | Diamond Lapping Film Discs | Traditional Abrasives (e.g., Al₂O₃, SiC) |
|---|---|---|
| Hardness | Mohs 10 (Diamond) | Mohs 9 (SiC) / Mohs 9 (Al₂O₃) |
| Lifespan | 3–5x longer | Frequent replacement required |
| Surface Finish | Mirror-like, sub-micron smoothness | Risk of scratches or uneven wear |
| Cost Efficiency | Higher upfront cost, lower long-term expense | Lower initial cost, higher recurring expenses |
Usage Guidelines
Grit Selection
-
Coarse (30–9µm): Rapid material removal or shaping.
-
Medium (6–3µm): Intermediate smoothing.
-
Fine (1–0.1µm): Final polishing for nanometer-level finishes.
Machine Compatibility
-
Compatible with lapping machines, rotary tools, or precision hand-held systems.
Best Practices
-
Use coolant/lubricant for heat-sensitive materials.
-
Clean discs regularly to prevent diamond particle clogging.
