4. Grade Details — CA525 Key Characteristics
The CA525 grade is a high-performance CVD-coated carbide specifically developed for steel machining. Its multi-layer coating architecture combines a thick TiCN layer with an Al₂O₃ top coat, delivering outstanding wear resistance and thermal stability.
- Substrate: Fine-grained tungsten carbide (WC-Co) with optimized cobalt content for toughness
- Coating Structure: TiCN (interlayer) + Al₂O₃ (outer layer) + TiN (gold top layer for wear detection)
- Color Code: Gold-yellow (TiN surface finish)
- ISO Application Range: P15-P35 (Steel, cast steel, long-chipping materials)
- Cutting Speed Capability: Up to 350 m/min in continuous cutting of carbon steel
- Temperature Resistance: Effective up to 900°C at the cutting edge
5. Grade Comparison Matrix
| Grade | Coating | Primary Material | Speed | Interruption |
|---|---|---|---|---|
| CA525 | CVD TiCN+Al₂O₃ | Steel, Cast Steel | Medium-High | Light to Moderate |

8. Application Map by Operation
| Operation | Suitability | Depth of Cut (ap) | Notes |
|---|---|---|---|
| External Turning | ★★★★★ Excellent | 1.0-4.0 mm | Primary application |
| Internal Turning | ★★★★☆ Very Good | 1.0-4.0 mm | Use with appropriate boring bar |
| Facing | ★★★★☆ Very Good | Up to 4.0 mm | Stable chip evacuation |
| Profiling | ★★★☆☆ Good | Light cuts | Radius-dependent corner fidelity |
| Grooving | ★★☆☆☆ Limited | Not recommended | Use dedicated grooving inserts |
9. Recommended Cutting Conditions
Parameters below are starting recommendations for continuous cutting of carbon steel (C45) using coolant. Adjust based on machine rigidity, workpiece condition, and desired tool life.
| Parameter | Symbol | Recommended Range | Unit |
|---|---|---|---|
| Cutting Speed | Vc | 120-220 | m/min |
| Feed Rate | f | 0.15-0.40 | mm/rev |
| Depth of Cut | ap | 1.0-4.0 | mm |
| Coolant | — | Emulsion (5-8%) or neat oil | — |
| Tool Overhang | — | Minimum possible | mm |
10. Operating Guidelines
- Toolholder Selection: Use negative-type WNMG toolholders (e.g., DWLNR, MWLNR series) with 0° clearance and adequate rake angle for the operation.
- Clamping Torque: Tighten the insert screw to 3.5–4.5 N·m. Over-tightening may distort the insert seat; under-tightening causes vibration.
- Coolant Delivery: Direct high-pressure coolant to the cutting zone. For WQ chipbreaker, aim at the chip groove to enhance chip breaking.
- Edge Inspection: Check for flank wear (VB max 0.3 mm) and crater wear. Replace when surface finish degrades or cutting force increases audibly.
- Entry Angle: Maintain a lead angle of 75°–95° for optimal chip control and reduced radial forces.
- Workpiece Runout: Ensure runout is below 0.02 mm for precision applications to prevent chipping.
11. Toolholder Compatibility
The WNMG080412WQ is compatible with standard ISO toolholders designed for WNMG 08 inserts. Recommended holder families include:
| Holder Series | Style | Approach Angle | Use Case |
|---|---|---|---|
| DWLNR / DWLNL | External, 95° | 95° | General external turning and facing |
| MWLNR / MWLNL | External, 95° | 95° | Heavy-duty machining |
| PWLNR / PWLNL | External, 95° | 95° | Precision finishing |
| EWLNR / EWLNL | Internal, 95° | 95° | Boring and internal turning |
| SWLNR / SWLNL | External, 45° | 45° | Profiling and facing |
Note: Verify holder seat dimensions (IC 12.7 mm, thickness 4.76mm) before ordering. Use Kyocera genuine toolholders for best performance.
