| Coolant Recommendation | Emulsion 8-10% | Emulsion 10-12% | Dry or Mist |
10. Operating Guidelines
- Always use sharp cutting edges for finishing operations; worn edges increase cutting forces and reduce surface quality.
- Ensure proper toolholder clamping force (torque: 4.5-6.0 Nm) to prevent insert movement during heavy cuts.
- Apply sufficient coolant flow (minimum 8% concentration) for steel machining to prevent built-up edge formation.
- For interrupted cuts, reduce cutting speed by 20-30% to prevent thermal shock and premature edge chipping.
- Verify toolholder seat condition before insert installation; damaged seats cause uneven load distribution.
- Use recommended nose radius for feed rate: fn ≤ 0.5 × corner radius to avoid notching and ensure surface finish.
- For CA125P grade: maintain consistent chip thickness to maximize PVD coating life and prevent delamination.
- For CA310 grade: suitable for dry machining on cast iron; coolant may be omitted to extend thermal crack resistance.
- Store inserts in original packaging away from direct sunlight and humidity to prevent corrosion of uncoated edges.
- Replace inserts at the first sign of flank wear (VB = 0.3 mm) to maintain dimensional accuracy and prevent catastrophic failure.
11. Toolholder Compatibility
The TNMG160404PMG is compatible with the following ISO-standard toolholder families:
| Toolholder Series | Approach Angle | Application |
|---|---|---|
| MTJNR/L (93°), MTQNR/L (75°), STGCR/L (91°) for 16mm inserts | Standard | External Turning |
| Kyocera Standard Clamp | Varies | Universal |
Important: Ensure toolholder pocket size matches IC 16 mm. Use Kyocera genuine toolholders for optimal insert life and safety.
