Recommended Cutting Conditions
Parameters below serve as starting points. Optimize based on machine rigidity, coolant delivery, and workpiece condition:
| Material | Cutting Speed (m/min) | Feed (mm/rev) | Depth of Cut (mm) |
|---|---|---|---|
| Low Carbon Steel | 200 - 280 | 0.08 - 0.20 | 0.2 - 1.5 |
| Medium Carbon Steel | 180 - 250 | 0.06 - 0.18 | 0.2 - 1.2 |
| Alloy Steel | 150 - 200 | 0.05 - 0.15 | 0.1 - 1.0 |
| Stainless Steel | 120 - 180 | 0.05 - 0.12 | 0.1 - 0.8 |
Values shown for stable setups with high-pressure coolant. Reduce speed by 20% for dry machining or low-rigidity setups.
Operating Guidelines
Follow these best practices to maximize tool life and part quality:
- Always use adequate coolant flow (minimum 5% concentration) for steel machining
- Ensure rigid toolholder setup to minimize vibration and maximize tool life
- Reduce cutting speed by 15% when entering interrupted cuts or scale-covered surfaces
- Maintain consistent feed rates to prevent built-up edge formation
- Inspect insert seating surface before mounting to ensure flat contact
- Use torque wrench for clamping screws to manufacturer specification (2.5-3.5 Nm)
- Replace insert when flank wear reaches 0.3 mm or crater wear exceeds 0.15 mm
Toolholder Compatibility
This insert is compatible with standard 60° triangular toolholders designed for positive inserts:
| Toolholder Series | Style | Compatibility |
|---|---|---|
| STGCR / STGCL | External Turning | Direct Fit |
| STWCR / STWCL | External Turning | Direct Fit |
| SCLCR / SCLCL | Boring Bar | Direct Fit |
| STFCR / STFCL | Face Turning | Direct Fit |
