Moresuperhard CBN Honing Stones are designed for High-Precision Resin Bond Honing Stone – Ideal for Fine Finishing of Small to Medium Bores
Applications of CBN Inserts
| Parameter | Specification |
|---|---|
| Dimensions | 1.3 mm (T) × 2 mm (W) × 60 mm (L) — standard for micro honing heads |
| Abrasive Type | CBN (Cubic Boron Nitride) – chemically stable with iron-based alloys |
| Equivalent Grit | ～600# (approx. 25 μm) – suitable for semi-finish to finish honing |
| Equivalent Hardness | Comparable to B30 resin bond – medium-soft for controlled cutting on hardened steel |
| Bond System | High-strength resin bond with optimized CBN concentration |
| Max Workpiece Hardness | Up to HRC 70 |
| Surface Finish | Achieves Ra 0.2–0.8 μm depending on pass and machine parameters |
| Packaging | 10 pieces per pack, vacuum-sealed for moisture protection |
💡Advantages of CBN Inserts
Unlike diamond, CBN does not react with iron, making it the only superabrasive suitable for steel honing. It outlasts conventional Al₂O₃ stones by 3–5× in hardened applications.
- High Dimensional Accuracy – Ensures precise and stable machining.
- Excellent Dimensional Consistency – Consistent results across multiple workpieces.
- Low Surface Roughness – Produces smooth finishes with minimal polishing needed.
- Burr-Free Machining – Reduces tearing and surface defects.
- High Processing Efficiency – Shorter cycle times, higher productivity.
- Superior Material Capability – Ideal for difficult-to-machine materials like HSS and cast iron.
✅ Recommended Applications
- Hardened bearing steel (e.g., SAE 52100, HRC 60+)
- Chilled cast iron hydraulic valve sleeves
- Case-hardened gear bores
- Powder metallurgy parts (e.g., ASP® series)
- Overlay-welded stainless steel components
❌ Not recommended for: Aluminum, copper, brass, or soft non-ferrous metals (use diamond abrasives instead).
✅ Key Benefits
- ✅ Long service life – reduces tool change frequency
- ✅ Consistent bore quality – minimal taper or roundness error
- ✅ No workpiece burn – excellent heat dissipation
- ✅ Smooth cross-hatch pattern – ideal for oil retention
- ✅ Compatible with standard honing heads – no special fixtures needed
⚙️ Usage Tips
- Speed: 150–250 RPM
- Lubrication: Light oil (e.g., kerosene or mineral oil) recommended
- Pressure: Use light, consistent pressure – let the CBN do the work
- Sequence: Use after rough honing with conventional stones (e.g., 240#)
