9. Recommended Cutting Conditions
| Workpiece Material | Cutting Speed Vc (m/min) | Feed per Tooth fz (mm) | Axial DOC ap (mm) |
|---|---|---|---|
| Mild Steel (≤30 HRC) | 100-240 | 0.040-0.140 | 1.2-2.5 |
| Alloy Steel (30–45 HRC) | 80-210 | 0.030-0.120 | 0.7-1.5 |
| Stainless Steel (≤35 HRC) | 70-195 | 0.025-0.110 | 0.5-1.0 |

| Aluminum Alloy | 180-360 | 0.060-0.170 | 1.7-3.5 |
Note: Values are starting recommendations. Adjust based on machine rigidity, coolant delivery, and workpiece fixturing. Use air blast or mist coolant for aluminum; flood coolant for steel and stainless steel.
10. Operating Guidelines
- Runout: Maintain spindle runout ≤ 0.005 mm (TIR) for optimal tool life and surface finish.
- Coolant: Flood coolant at 6–8% concentration recommended for steel and stainless. For aluminum, use air blast or minimum quantity lubrication (MQL) to prevent chip welding.
- Ramp Entry: Use helical ramp entry at 1–2° angle or pre-drill pilot hole to avoid full-width engagement shock.
- Corner Engagement: Reduce feed rate by 30–40% when cutting internal corners to prevent chip overload and tool breakage.
- Tool Overhang: Keep overhang-to-diameter ratio ≤ 4:1. Use shrink-fit or hydraulic chucks for best results.
- Speed/Feed Adjustment: Reduce cutting speed by 15% for every 5 HRC above grade recommendation.
- Inspection: Inspect cutting edges under magnification (≥20×) before each use. Do not use chipped or worn tools.
11. Toolholder Compatibility
| Toolholder Type | Taper / Interface | Max RPM | Remarks |
