4. Grade Details – Key Grade Characteristics

CA315 is a high-performance CVD-coated carbide grade engineered specifically for steel machining. CVD-coated carbide grade featuring TiCN/Al₂O₃/TiN multi-layer coating. Balances wear resistance and toughness for steel machining.

  • Substrate: High-toughness tungsten carbide (WC-Co) with optimized grain structure
  • Coating: Multi-layer CVD (TiCN base + Al₂O₃ middle + TiN top), total thickness ~8–12 μm
  • Coating Color: Gold/Yellow (TiN top layer)
  • Hardness: 1,500 HV (coating surface)
  • Transverse Rupture Strength: 2,800 MPa
  • Operating Temperature: Up to 900°C in the cutting zone
  • ISO Application Range: P15–P30 (Steel machining)

Stainless Steel (Austenitic)100–150 m/min0.12–0.25 mm/rev0.5–2.0 mm

10. Operating Guidelines

  • Coolant: High-pressure coolant (70–100 bar) recommended for chip evacuation and temperature control. Use water-soluble coolant with 8–10% concentration.
  • Entry Angle: Maintain 91–95° tool entry angle for optimal chip control and minimal notch wear.
  • Edge Preparation: Standard T-land (0.05 mm × 20°) suitable for most steel applications. For interrupted cuts, consider honed edge (0.08 mm radius).
  • Speed Adjustment: Reduce cutting speed by 15–20% for interrupted cuts or scale/rusty surfaces. Increase by 10% for continuous cuts with stable setup.
  • Feed Rate: Minimum feed should not fall below 0.10 mm/rev to ensure proper chip formation and avoid built-up edge.
  • Depth of Cut: Avoid depths below 0.3 mm when using chipbreaker inserts to prevent rubbing and premature wear.
  • Tool Overhang: Minimize tool overhang to 1.5× insert size for maximum rigidity and vibration damping.

11. Toolholder Compatibility

The SPMN120408 is compatible with standard ISO toolholders designed for square (80°) inserts with 11° (positive) clearance. Recommended holder styles:

  • Standard Holders: SCMCN, SCGBR/L (positive square holders)
  • Insert Clamp: Lever lock or top clamp system with carbide shim
  • Shim Requirement: Use carbide shim matching insert size (e.g., 12.7 mm IC shim) for protection and height consistency
  • Shim Seat Angle: Must match insert clearance angle (11°)
  • Holder Material: Alloy steel (42CrMo4) with hardened pocket (50–55 HRC)
  • Compatibility Check: Verify holder pocket size (IC 12.7 mm) and clamp type match insert hole pattern
