4. Grade Details – Key Grade Characteristics

Grade CA510 is a high-performance PVD-coated grade developed for medium to high-speed machining of steel, stainless steel, and cast iron. The substrate features a micro-grain tungsten carbide structure with 10% cobalt binder, providing an optimal balance of hardness and toughness.

• Substrate: Micro-grain tungsten carbide (WC-Co) with 10% cobalt binder
• Coating: PVD multi-layer TiAlN coating (Gold-colored)
• Hardness: HRA 91.5
• Transverse Rupture Strength: ≥ 2,800 MPa
• Thermal Conductivity: 58 W/m·K
• Coating Hardness: HV 3,200
• Max Operating Temperature: 900°C

Key Performance Characteristics:

• Excellent wear resistance at medium to high cutting speeds
• High thermal stability for dry and wet machining environments
• Strong adhesion between substrate and coating layers
• Good balance between toughness and hardness
• Superior crater wear resistance in steel machining

9. Recommended Cutting Conditions

Parameters below are starting recommendations for stable setups with runout < 0.01 mm. Adjust based on machine rigidity, workpiece fixturing, and desired tool life.

Note: Reduce speeds by 15–20% for interrupted cuts or poor machine rigidity. Increase by 10% for stable, high-rigidity CNC centers.

10. Operating Guidelines

• Insert Inspection: Verify cutting edge integrity before mounting. Discard inserts with micro-chips or coating delamination.
• Toolholder Selection: Use precision-ground holders (runout < 0.01 mm) to maximize insert life and surface finish.
• Cutting Fluid: Wet / MQL recommended. Ensure coolant concentration 5–8% for emulsion systems.
• Entry Strategy: Use ramp entry or rounded corner approach; avoid direct plunge into solid material.
• Speed Ramp: Start at 70% of recommended Vc for the first 5 minutes, then increase to optimal range.
• Chip Management: Verify chip curling and breakage. Long chips indicate insufficient feed or worn insert.
• Tool Life Monitoring: Track flank wear (VB). Replace when VB ≥ 0.3 mm or when surface finish degrades.
• Storage: Keep inserts in original packaging at 15–25°C, humidity < 60%. Avoid direct sunlight.

11. Toolholder Compatibility

The WNMG08 series requires holders with 80° trigon seating and appropriate clamping mechanisms. Below are compatible Kyocera and industry-standard holder families:

Mounting Notes: Ensure the insert seat is clean and free of burrs. Torque clamping screws to 2.5–3.0 N·m. Use a torque wrench for repeatable clamping force. Verify insert seating with a dial indicator before first cut.
