Rleey | Surface Treatment Options for OEM Custom Tungsten Carbide Blades: Polishing & Coating
Full Article Structure
1. Introduction: Why Surface Treatment Matters for Carbide Blades
As-ground carbide surfaces have tiny grinding marks, which may cause material sticking and extra friction. Proper polishing or coating can reduce adhesion, improve surface smoothness and extend blade service life. Rleey supports adding surface finishing on custom carbide blades according to your cutting materials and requirements.
2. Polishing Types & Application Scenarios
- Fine grinding finish: standard option, low cost, suitable for general slitting
- Fine polishing: remove grinding lines, less sticking for plastic and film cutting
- Mirror polishing: ultra-smooth surface, ideal for sticky adhesive film and rubber cutting
3. Common PVD Coatings for Carbide Cutting Blades
We provide TiN, TiCN, AlTiN coatings. TiN reduces friction and anti-sticking; TiCN balances wear resistance and toughness; AlTiN works well for high-temperature cutting with abrasive materials. Coating is an extra process and will add production lead time.
4. Surface Treatment Comparison Table
| Finish Type | Main Advantage | Best For |
|---|---|---|
| As-ground | Standard cost, fast delivery | Paper, non-woven fabric, general wood cutting |
| Fine Polishing | Low friction, less adhesion | Plastic film, thin foam, light adhesive material |
| Mirror Polishing | Ultra-smooth, anti-sticking | Rubber, adhesive tape, sticky film |
| PVD Coating | Better wear & heat resistance | Abrasive composite, high-speed continuous cutting |
5. FAQ for Polishing & Coating Service
Q1: Can coating be applied only on the cutting edge?
Yes, edge-only coating is available, full surface coating is also acceptable.
Q2: Will polishing or coating change blade dimension tolerance?
Polishing and coating have tiny thickness changes; we control dimension before treatment to keep your tolerance requirement.
