Chipbreaker Profile
The CNMG120408CJ series features a precision-ground chipbreaker geometry optimized for turning insert performance:
- Chipbreaker Type: CJ — Heavy duty, interrupted cutting
- Rake Face Angle: -6° to -8° (negative rake) for maximum edge strength
- Land Width: 0.10 – 0.20 mm T-land for edge stability and finish quality
- Chip Groove Depth: 0.15 – 0.30 mm, designed to curl and break chips efficiently
- Edge Preparation: Micro-honed edge (0.02–0.04 mm) to prevent chipping and extend tool life
- Surface Finish: Polished rake face (Ra 0.2 µm) minimizes built-up edge and improves chip flow

Operating Guidelines
- Tool Overhang: Minimize overhang to 4× insert size or less to prevent vibration and chatter
- Coolant Recommendation: Use water-soluble coolant (6–8% concentration) at 6–10 bar for chip evacuation and heat control
- Entry Angle: Maintain approach angle of 93°–95° for external turning to maximize insert engagement
- Edge Conditioning: Inspect insert seating surface before installation; clean with compressed air
- Torque Specification: Tighten clamping screw to 2.5–3.5 N·m; do not overtighten to avoid insert cracking
- Tool Change Criteria: Replace insert when flank wear (VB) exceeds 0.3 mm or when surface finish degrades noticeably
- Index Frequency: Rotate to unused cutting edge every 15–30 minutes of continuous cutting for balanced wear
- Storage: Store in original packaging at 15–25°C, humidity <60%, away from corrosive vapors
