9. Recommended Cutting Conditions
Values are indicative. Always perform test cuts and optimize for your specific machine tool, workpiece material, and setup rigidity.
| Material | Cutting Speed Vc (m/min) | Feed fn (mm/rev) | Coolant Pressure |
|---|---|---|---|
| Carbon Steel (Roughing) | 100 | 0.252 | 70-100 bar |
| Carbon Steel (Finishing) | 151 | 0.131 | 100-150 bar |
| Alloy Steel | 90 | 0.232 | 80-120 bar |
| Stainless Steel | 80 | 0.222 | 100-150 bar |
| Cast Iron | 141 | 0.272 | 50-80 bar |
| Hardened Steel (45-50 HRC) | 60 | 0.111 | 120-180 bar |
10. Operating Guidelines
- Pecking Cycle: For depths > 5×D, use a peck depth of 1.5–2.0×D with full retract to break chips.
- Coolant Requirement: Internal coolant is mandatory. Minimum flow rate: 15 L/min at 80 bar for optimal tool life.
- Entry Surface: Ensure flat, perpendicular entry surface. Chamfer or spot-drill if surface is irregular or angled > 2°.
- Pre-hole: Not required for standard applications. For cross-holes or inclined entry, pilot with a short drill first.
- Spindle Runout: Maintain TIR ≤ 0.01 mm at the tool tip to prevent uneven wear and premature failure.
- Tool Overhang: Minimize overhang. Use hydraulic or shrink-fit holders for best results. Collet chucks are not recommended for 12×D applications.
- Chip Control: Monitor chip shape. Acceptable chips are short C- or 6-shaped curls. Long stringy chips indicate insufficient feed or coolant.
11. Toolholder Compatibility
| Holder Type | Taper / Interface | Clamping Force | Suitability |
|---|---|---|---|
| Hydraulic Chuck | HSK-A63 / BT40 | High | ★★★★★ Best for 12×D |
| Shrink Fit Holder | HSK-A63 / BT40 | Very High | ★★★★★ Best for 12×D |
| Precision Collet (ER25/ER32) | BT40 / SK40 | Medium | ★★★☆☆ Acceptable up to 8×D |
| Milling Chuck | BT40 / HSK-A63 | High | ★★★★☆ Good for rigid setups |
| Weldon Flat Holder | BT40 / DIN 69871 | Medium | ★★☆☆☆ Not recommended for 12×D |
