Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| External Longitudinal Turning | ★★★★★ | Primary application; stable chip control |
| Face Turning (Facing) | ★★★★☆ | Excellent toward center; reduce feed by 20% |
| Internal Boring | ★★★★☆ | Use minimum overhang for stability |
| Profiling / Contouring | ★★★★☆ | 55° nose angle enables undercut access |
| Shoulder Turning | ★★★☆☆ | Possible with reduced depth of cut |
| Parting / Grooving | ★☆☆☆☆ | Not recommended; use dedicated parting inserts |
| Threading | ☆☆☆☆☆ | Not applicable |
Recommended Cutting Conditions
Parameters below are starting recommendations for continuous cutting of carbon steel (P.1). Adjust based on machine rigidity, workpiece condition, and required surface finish.
| Parameter | Range | Optimal Start |
|---|---|---|
| Cutting Speed (Vc) | 100–220 m/min | 100 |
| Feed Rate (f) | 0.10–0.40 mm/rev | 0.10 |
| Depth of Cut (ap) | 0.5–3.5 mm | 0.5 |
| Coolant Recommendation | Emulsion (5–8%) or Synthetic | High-pressure coolant preferred |
Operating Guidelines
- Tool Overhang: Keep toolholder overhang to ≤ 4× shank diameter for boring; ≤ 1.5× for external turning.
- Insert Seating: Ensure insert pocket is clean and free of chip debris before clamping. Torque clamping screw to 2.5–3.0 N·m.
- Coolant Flow: Direct coolant nozzle to the cutting zone at 15–20° from tool rake face. Minimum flow rate: 15 L/min.
- Entry Strategy: Use ramp entry or rounded corner approach; avoid plunging directly into solid material.
- Chip Evacuation: Verify chip curling and evacuation every 10 minutes during unattended operation.
- Edge Inspection: Inspect cutting edge under 10× magnification after 30 min of continuous cutting for flank wear.
- Wear Criteria: Retire insert when flank wear (VB) exceeds 0.3 mm or when surface finish degrades beyond Ra 1.6 µm.
Toolholder Compatibility
This insert requires a negative-rake toolholder with a 55° rhombic pocket. Compatible holder series include:
| Toolholder Series | Style | Application |
|---|---|---|
| DDJNR | External Turning | Right-hand / Left-hand |
| DDJNL | External Turning | Right-hand / Left-hand |
| S16Q-SDJCR/L | Internal Boring | 16 mm diameter shank |
| S20R-SDJCR/L | Internal Boring | 20 mm diameter shank |
| PDJNR/L | Face Turning | 90° approach angle |
Tip: Use a toolholder with precision-ground pockets (G-class or better) to maximize insert life and surface finish.
