| Hardened Steel (>50 HRC) | H.1 – H.2 | ★★★☆☆ | Hard milling, die & mold |
Application Map by Operation
| Operation | Suitability | Recommended Strategy |
|---|---|---|
| Side / Peripheral Milling | ★★★★★ | ae = 0.5 – 0.8 × DC, high vc |
| Slot Milling (Full Slot) | ★★★★☆ | ae = 1.0 × DC, reduce fz by 20% |
| Plunge Milling | ★★★☆☆ | Use ramp entry; max 2° ramp angle |
| Contour / 3D Profiling | ★★★★★ | Stepover 5 – 10% of DC for fine finish |
| High-Feed Milling | ★★★★☆ | fz = 0.15 – 0.25 mm/tooth, ae = 0.2 × DC |
Recommended Cutting Conditions
| Material | Cutting Speed vc (m/min) | Feed per Tooth fz (mm) | Axial Depth ap (mm) | Coolant |
|---|---|---|---|---|
| Low-Alloy Steel (< 700 N/mm²) | 120 – 180 | 0.08 – 0.15 | ≤ 1.5 × DC | Emulsion / Compressed air |
| Stainless Steel (AISI 304/316) | 60 – 100 | 0.06 – 0.12 | ≤ 1.0 × DC | High-pressure internal coolant |
| Cast Iron (GG/GGG) | 100 – 160 | 0.10 – 0.18 | ≤ 2.0 × DC | Dry / Minimum quantity lubrication |
| Hardened Steel (45 – 55 HRC) | 40 – 80 | 0.03 – 0.08 | ≤ 0.5 × DC | Air blast / MQL |
| Titanium (Ti-6Al-4V) | 30 – 60 | 0.05 – 0.10 | ≤ 0.8 × DC | High-volume flood coolant |
Operating Guidelines
- Run-out check: Ensure toolholder TIR < 0.01 mm at the tool tip to maximize tool life and surface finish.
- Entry strategy: Use helical or ramp entry for plunging; avoid direct vertical plunging except in dedicated plunge-milling cycles.
- Coolant: For stainless steel and titanium, high-pressure internal coolant (≥ 70 bar) is strongly recommended to prevent chip recutting and built-up edge.
- Speed & feed tuning: Start at the lower end of the recommended range and increase incrementally while monitoring spindle load and surface finish.
- Tool change interval: Inspect cutting edges after every 30 – 60 minutes of cutting time; replace at first sign of flank wear > 0.15 mm or chipping.
Toolholder Compatibility
| Holder Type | Standard | Taper / Fit | Notes |
|---|---|---|---|
| Hydraulic Chuck | DIN 69871 / ISO 7388 | HSK-A63 / BT40 | Best for finishing; excellent damping |
| Shrink Fit | DIN 69893 | HSK-E32 / HSK-E40 | Optimal for high-speed machining |
| Collet Chuck (ER) | DIN 6499 | ER16 / ER20 / ER25 | Verify collet precision grade (≥ AA) |
| Milling Chuck | DIN 1835 | Weldon / Whistle-Notch | Secure for heavy roughing |
