Grade Details – Key Grade Characteristics
Grade CA320: PVD-coated carbide grade with TiAlN multilayer coating. Excellent balance of wear resistance and toughness. Optimal for steel and stainless steel machining at medium to high cutting speeds. Operating temperature range: 800–1,000°C.
- Substrate: Fine-grained tungsten carbide (WC-Co) with 10% cobalt binder for enhanced toughness
- Coating: Multi-layer TiAlN PVD coating (3–5 μm total thickness) with superior oxidation resistance
- Hardness: 1,520 HV (Vickers) – suitable for high-speed machining of ferrous materials
- Transverse Rupture Strength: 2,800 MPa – handles interrupted cuts and scale-covered surfaces
- Thermal Conductivity: 45 W/m·K – efficient heat dissipation to prolong tool life
- Color Code: Bronze-copper (typical for TiAlN coated grades)

Application Map by Operation
Suitability matrix for common turning operations:
| Operation Type | Suitability | Recommended Parameters | Notes |
|---|---|---|---|
| External Turning | ✓ Excellent | Standard parameters | Primary application |
| Internal Turning / Boring | ✓ Good | Reduce speed by 10-15% | Ensure adequate coolant flow |
| Facing | ✓ Excellent | Standard parameters | Watch for chip evacuation near center |
| Profiling / Contouring | ✓ Good to Excellent | Reduce feed for fine profiles | Nose radius dependent |
| Grooving / Cut-off | ✗ Not Recommended | — | Use dedicated grooving inserts |
| Threading | ✗ Not Recommended | — | Use dedicated threading inserts |
Recommended Cutting Conditions
Starting parameters for stable machining. Adjust based on machine condition, rigidity, and coolant delivery:
| Workpiece Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Depth of Cut ap (mm) |
|---|---|---|---|
| Carbon Steel (P.1 – P.3) | 160 – 260 | 0.10 – 0.35 | 1.0 – 4.0 |
| Alloy Steel (P.4 – P.6) | 140 – 230 | 0.10 – 0.35 | 1.0 – 4.0 |
| Stainless Steel (M.1 – M.2) | 110 – 180 | 0.10 – 0.35 | 1.0 – 4.0 |
| Cast Iron (K.1 – K.3) | 140 – 230 | 0.10 – 0.35 | 1.0 – 4.0 |
| Hardened Steel (H.1 – H.2) | 80 – 140 | 0.05 – 0.15 | 0.2 – 1.0 |
*Values are starting recommendations. Optimize based on machine rigidity, coolant, and workpiece condition. Grade CA320 performs best at medium-to-high cutting speeds.
Operating Guidelines
- Coolant: High-pressure coolant (70+ bar) recommended for chip evacuation and heat dissipation. Minimum 5% concentration for water-miscible coolants.
- Tool Overhang: Keep toolholder overhang to minimum possible. For every 10mm increase in overhang, reduce cutting speed by 5-8%.
- Insert Seat: Ensure insert seat is clean and free of chips before seating. Torque clamping screw to 2.5–3.5 Nm.
- Edge Preparation: Do not touch cutting edge with bare fingers. Oils can cause micro-chipping at high temperatures.
- First Cut: Start at lower end of recommended speed range and increase gradually while monitoring tool wear and surface finish.
- Tool Life Monitoring: Inspect flank wear (VB) regularly. Replace insert when VB exceeds 0.3mm for roughing or 0.15mm for finishing.
- Chip Control: If chips are too long or tangled, increase feed rate by 10% or verify coolant nozzle alignment.

Compatible Toolholder Families:
MTJNR, MTJNL, MTQNR, MTQNL, STGCR, STGCL (for 16-size); MTJNR/L16, MTQNR/L16 (for 22-size)
