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)

*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.
