Grade Details – Key Grade Characteristics
The CA025P grade is a CVD-coated carbide grade specifically developed for steel machining applications. It belongs to the ISO P25 application group and offers the following characteristics:
- Advanced CVD multi-layer coating (TiCN + Al₂O₃ + TiN) provides exceptional wear resistance and thermal stability.
- Substrate engineered with medium cobalt content for optimal balance between hardness and toughness.
- Optimized for medium cutting speeds with consistent performance across wet and dry machining conditions.
- Excellent resistance to crater wear and flank wear in continuous and light interrupted cutting.
- Designed for stable machining of steels in the ISO P25 application group with predictable tool life.
Grade Comparison Matrix
| Grade | ISO Range | Wear Resistance | Workpiece Materials | Typical Applications |
|---|---|---|---|---|
| CA025P | P25 | Medium | Steel / Cast Iron | General-purpose turning, balanced performance |
| CA025P | P20–P30 | Medium–High | Carbon & Alloy Steels | Finish to medium roughing applications |
| CA025P | P25–P35 | Medium | Steel, Stainless | Versatile grade for mixed production |
Chipbreaker Profile
Standard – General Purpose
Standard chipbreaker profile for versatile turning applications. Reliable chip control across moderate cutting parameters.
The Standard chipbreaker geometry is optimized for external turning, facing, profiling. Its carefully engineered rake angle and land width promote efficient chip curling and breakage, reducing the risk of chip entanglement and improving surface finish quality.
Recommended Applications & Workpiece Materials
| Material Group | Examples | Machinability | Recommended |
|---|---|---|---|
| Carbon Steels | C35, C45, C50, C60 | Good | ✓ Excellent |
| Alloy Steels | 42CrMo4, 34CrNiMo6, 16MnCr5 | Good–Moderate | ✓ Excellent |
| Tool Steels | H13, D2, O1 (annealed) | Moderate | ✓ Good |
| Bearing Steels | 100Cr6, 52100 | Moderate | ✓ Good |
| Structural Steels | S235JR, S355JR, St52-3 | Good | ✓ Excellent |
Application Map by Operation
| Operation Type | Suitability | Depth of Cut (ap) | Feed Rate (fn) |
|---|---|---|---|
| External Turning | ★★★★★ | 0.50–3.00 mm | 0.10–0.30 mm/rev |
| Internal Turning | ★★★★☆ | 0.50–3.00 mm | 0.10–0.30 mm/rev |
| Facing | ★★★★★ | 0.50–3.00 mm | 0.10–0.30 mm/rev |
| Profiling | ★★★★☆ | 0.20–2.00 mm | 0.10–0.25 mm/rev |
| Interrupted Cutting | ★★★☆☆ | 0.50–2.00 mm | 0.10–0.20 mm/rev |
Recommended Cutting Conditions
The following cutting parameters are recommended for machining carbon and alloy steels with the CNMG120404 insert:
| Depth of Cut (ap) | Feed Rate (fn) | Cutting Speed (Vc) |
|---|---|---|
| 0.50–1.00 mm | 0.10–0.15 mm/rev | 180–250 m/min |
| 1.00–2.00 mm | 0.15–0.22 mm/rev | 160–220 m/min |
| 2.00–3.00 mm | 0.22–0.30 mm/rev | 140–190 m/min |
Note: Values are guidelines. Actual parameters should be adjusted based on machine rigidity, workpiece material condition, and coolant application. Reduce cutting speed by 15–20% for dry machining or interrupted cuts.
Operating Guidelines
- Coolant: Water-soluble coolant or neat cutting oil is recommended for optimal tool life and surface finish. Minimum coolant concentration: 5–8%.
- Tool Overhang: Minimize tool overhang to reduce vibration. Use the shortest possible toolholder for the application.
- Insert Seating: Ensure the insert seat is clean and free of chips before mounting. Torque the clamping screw to manufacturer specifications (typically 3.5–4.5 Nm).
- Entry Angle: Maintain a recommended entry angle of 90–95° for external turning to distribute cutting forces evenly.
- Edge Preparation: Do not re-sharpen or re-coat the insert. Kyocera inserts are precision-ground and coated for single-use indexing.
- Index Frequency: Inspect the cutting edge after each indexing. Replace the insert when flank wear exceeds 0.3 mm or when chipping/cratering is observed.
Toolholder Compatibility
The CNMG120404 insert is compatible with the following standard Kyocera toolholder series (size 12):
| Toolholder Designation | Style | Hand | Insert Size |
