Why Use Diamond Lapping Film for End Mills?

Diamond abrasives are the industry benchmark for tool polishing. XYT’s films combine ultra-flat polyester backing with precision-graded diamond grit to:

• Eliminate micro-burrs and tool marks

• Minimize edge rounding for sharper cutting performance

• Operate coolly to protect carbide substrates

Whether hand-held or machine-mounted, these films outperform conventional wheels and pastes, delivering Ra values below 0.03 µm with minimal heat generation.

Comparing 6 µm vs. 3 µm Grit Sizes

Workflow Tip: Begin with 6 µm film to smooth out any residual scratches, then switch to 3 µm for the ultimate mirror sheen.

Key Product Features

• Precision Diamond Abrasive: Uniform particle distribution for consistent cut and finish

• 3 mil Polyester Backing: Rigid yet flexible; resists stretch, ensures even pressure

• Advanced Bonding: Prevents grit pull-out, prolonging film life and reducing cost per finish

• Low-Friction Polishing: Limits heat build-up, preserving carbide microstructure

• Adaptable Format: Sheets and rolls compatible with platen, hand-held, or spindle polishing

Step-by-Step Bright Finishing Process

1. Clean & Prep: Remove coolant residues with solvent; dry thoroughly.

2. Rough Polish (6 µm):

   • Affix film to flat platen or stiff backing block.

   • Apply moderate pressure with linear or circular strokes.

3. Intermediate Rinse: Wipe away slurry with isopropyl alcohol; inspect for remaining marks.

4. Final Polish (3 µm):

   • Repeat polishing using light, even strokes until a mirror finish appears.

5. Quality Check:

   • Use a profilometer to verify Ra < 0.03 µm.

   • Visually confirm edge sharpness and gloss level.

Industrial Applications

• Cutting Tools: Carbide, HSS, and PCD end mills

• Mold & Die: Crisp cavity surfaces and fine detail work

• Aerospace Components: Tight-tolerance, high-gloss features

• Medical Devices: Ultra-smooth surfaces for biocompatibility

Benefits for Machinists & Manufacturers

• Extended Tool Life: Smoother cutting edges resist chipping and coating delamination

• Enhanced Surface Quality: Mirror finishes improve part aesthetics and reduce post-processing

• Process Efficiency: Faster cycle times vs. traditional polishing wheels and compounds

• Cost-Effective: Durable films lower consumable costs and downtime

SEO-Optimized FAQs

Q1: What grit sequence should I follow for end mill polishing?

Start with 6 µm to remove fine scratches, then finish with 3 µm for a mirror-bright surface.

Q2: How does XYT Diamond Film compare to polishing pastes?

Diamond films provide uniform grit distribution, cleaner operation, and lower heat generation than pastes.

Q3: Can I use these films on complex geometries?

Yes—flexible backing conforms to flutes and small-bore features when mounted on a contoured block.

Conclusion & Next Steps

For precision bright finishing of end mills, XYT Diamond 6 µm and 3 µm Lapping Films set the standard. Their engineered backing, consistent diamond abrasive, and easy-to-use format streamline your polishing workflow—yielding superior finishes and longer tool life.
