Recommended Cutting Conditions
The following parameters are recommended starting points. Adjust based on machine rigidity, workpiece condition, and coolant application.
| Operation | Depth of Cut (ap) | Feed (fn) | Cutting Speed (vc) | Coolant |
|---|---|---|---|---|
| Finishing | 0.1 – 1.0 mm | 0.05 – 0.15 mm/rev | 220-280 m/min | Flood or mist |
| Semi-Finishing | 0.5 – 2.5 mm | 0.10 – 0.25 mm/rev | 180-250 m/min | Flood or mist |
| Medium Machining | 1.0 – 4.0 mm | 0.15 – 0.35 mm/rev | 150-220 m/min | High-pressure recommended |
| Roughing | 2.5 – 6.0 mm | 0.25 – 0.60 mm/rev | 100-180 m/min | High-pressure recommended |
Operating Guidelines
- Tool Setup: Ensure insert seat is clean and free of debris before clamping. Use correct torque specification for clamping screw (typically 2.5–3.5 N·m).
- Run-In Period: For new inserts, reduce cutting speed by 20% for the first 5 minutes to stabilize the coating and prevent thermal shock.
- Chip Control: Verify chip shape regularly. Long, stringy chips indicate insufficient feed or incorrect chipbreaker selection. Adjust feed or coolant pressure accordingly.
- Coolant: Use water-soluble coolant at 6–8% concentration for steel. For cast iron, dry machining or minimum quantity lubrication (MQL) is often preferred.
- Tool Life Monitoring: Monitor flank wear (VB) every 15–20 minutes. Replace insert when VB exceeds 0.3 mm for finishing or 0.5 mm for roughing operations.
- Storage: Store inserts in original packaging away from direct sunlight and humidity. Avoid contact between inserts to prevent chipping of cutting edges.
Toolholder Compatibility
The following toolholder families are compatible with this insert geometry. Always verify holder designation matches insert shape and angle.
| Toolholder Family | Approach Angle | Application |
|---|---|---|
| MCMNN | 93° | General external turning |
| MCBNR/L | 93° | General external turning |
| PCLNR/L | 95° | External turning, facing |
| DCLNR/L | 95° | General external turning |
Tip: Use precision shim seats for finishing applications and rigid holders for roughing to maximize insert life and surface quality.
