Recommended Cutting Conditions
Parameters below are starting recommendations for continuous turning of carbon steel (ISO P.1). Adjust based on machine rigidity, workpiece condition, and desired surface finish.
| Parameter | Min | Recommended | Max |
|---|---|---|---|
| Cutting Speed (Vc) | 180 m/min | 240 m/min | 300 m/min |
| Feed Rate (fn) | 0.05 mm/rev | 0.12 mm/rev | 0.2 mm/rev |
| Depth of Cut (ap) | 0.2 mm | 0.8 mm | 1.5 mm |
| Coolant | Wet / Dry | Wet (high-pressure preferred) | — |
Operating Guidelines
- Always verify toolholder clamping force before operation. Insufficient clamping leads to vibration and premature insert failure.
- Use high-pressure coolant (≥ 70 bar) for best chip evacuation and surface finish, especially in deep-hole boring applications.
- For finish turning, reduce feed rate to the lower end of the recommended range to achieve Ra 0.4–0.8 µm surface roughness.
- When machining stainless steel, reduce cutting speed by 15–20% compared to carbon steel to minimize built-up edge (BUE).
- Inspect the insert edge after every 30–45 minutes of cutting time; replace at the first sign of flank wear exceeding 0.3 mm.
- Store unused inserts in original packaging away from moisture and direct sunlight to preserve coating integrity.
Toolholder Compatibility
This insert is compatible with the following standard ISO toolholder families:
| Toolholder Family | Description | Approach Angle |
|---|---|---|
| STFCR/L | Negative rake toolholders with 0° clearance angle — Screw clamp | 93° |
| MTFNR/L | Negative rake toolholders with 0° clearance angle — Lever lock | 93° |
| PTFNR/L | Negative rake toolholders with 0° clearance angle — Pin lock | 75° |
Ensure the selected toolholder matches the insert thickness (3.18 mm) and hole diameter. Verify shim seat condition to prevent insert fracture.
