Application Map by Operation
Visual suitability matrix for TNMG160404PS across common turning operations:
| Operation Type | Suitability |
|---|---|
| Roughing | ★☆☆☆☆ Not Recommended |
| Semi-Roughing | ★★☆☆☆ Fair |
| Semi-Finishing | ★★★★☆ Very Good |
| Finishing | ★★★★★ Excellent |
| Precision / Mirror | ★★★★☆ Very Good |
Recommended Cutting Conditions
Optimized parameters for CA025P grade when machining plain carbon and alloy steels (dry or MQL lubrication):
| Parameter | Recommended Range | Unit |
|---|---|---|
| Cutting Speed (Vc) | 234–390 | m/min |
| Feed Rate (fn) | 0.05–0.20 | mm/rev |
| Depth of Cut (ap) | 0.1–1.5 | mm |
Note: Values are starting recommendations. Adjust based on machine rigidity, workpiece condition, and desired surface finish. Reduce Vc by 15–20% for interrupted cuts or hardened materials.
Operating Guidelines
- Always verify toolholder seat cleanliness before insert indexing to prevent micro-chipping.
- Use minimum quantity lubrication (MQL) or dry cutting for optimal cermet performance; avoid flood coolant with high thermal shock.
- Maintain consistent feed rates to prevent built-up edge (BUE) formation on low-carbon steels.
- For finishing operations, reduce depth of cut to <0.5 mm and increase cutting speed to upper range for mirror surfaces.
- Index the insert after visible flank wear (VB) reaches 0.15 mm to protect the toolholder seat.
- Store unused inserts in original packaging away from direct sunlight and moisture.
Toolholder Compatibility
The TNMG160404PS is designed for standard TNMG toolholders with negative rake seats. Compatible holder families include:
- External Turning: MTJNR/L 16-4D, STGCR/L 16-3B, DTGCR/L 16-4C
- Internal Boring: S16S-SCLCR/L, A16S-MCLNR/L
- Clamp Type: Lever-lock or top-clamp (depending on holder design)
- Seat Angle: 0° (negative rake) – do not use in positive rake holders
