7. Recommended Applications & Workpiece Materials
Primary Materials: Hardened Steel (up to 55 HRC), Tool Steel, Alloy Steel, Cast Iron
| Material | Machinability | Recommended? | Notes |
|---|---|---|---|
| Carbon Steel (≤ 45 HRC) | Good | ✓ Yes | Excellent chip control |
| Alloy Steel (≤ 50 HRC) | Good | ✓ Yes | Use TN or TC grade |
| Stainless Steel 304/316 | Moderate | ✓ Yes | TA grade recommended for 316 |
| Cast Iron (Gray/Ductile) | Good | ✓ Yes | High-speed capable |
| Aluminum Alloys | Excellent | ✓ Yes | CA grade preferred |
| Hardened Steel (50-55 HRC) | Moderate | △ With Care | TC grade only |
| Titanium Ti-6Al-4V | Difficult | △ With Care | TA grade, low speeds |
| Inconel 718 | Difficult | △ With Care | TA grade, rigid setup |
8. Application Map by Operation
| Operation | Suitability | Recommended Parameters |
|---|---|---|
| Slotting (Full Width) | ✓ Excellent | ap = 3.2 mm, ae = D1 |
| Side Profiling | ✓ Excellent | ap = 1×D1, ae = 0.2×D1 |
| Contour Finishing | ✓ Good | ap = 0.5×D1, ae = 0.1×D1 |
| Plunging | ✓ Good | Peck cycle recommended |
| Ramp Milling | ✓ Good | Max 15° ramp angle |
| Helical Interpolation | ✓ Good | Entry dia ≥ 1.2×D1 |
9. Recommended Cutting Conditions
| Material | Vc (m/min) | fz (mm/tooth) | ap (mm) | ae (mm) |
|---|---|---|---|---|
| Carbon Steel | 100-150 | 0.03-0.08 | 3.2 | 0.2×D1 |
| Stainless Steel | 80-110 | 0.02-0.06 | 3.2 | 0.15×D1 |
| Cast Iron | 90-120 | 0.04-0.09 | 3.2 | 0.25×D1 |
| Aluminum | 200-300 (CA grade only) | 0.05-0.12 | 3.2 | 0.3×D1 |
Note: Values are starting recommendations. Adjust based on machine rigidity, coolant delivery, and workpiece fixturing. For TC grade, reduce speeds by 15% when machining materials above 40 HRC.
10. Operating Guidelines
- Runout Check: Ensure tool runout is ≤ 5 µm at the tool tip. Excessive runout reduces tool life by 30-50%.
- Coolant: Flood coolant recommended for steel and stainless steel. For aluminum with CA grade, air blast or mist is acceptable. TA grade supports dry machining on titanium.
- Entry Strategy: Use helical interpolation or ramp entry. Avoid direct plunging with square endmills.
- Chip Evacuation: Maintain adequate coolant pressure (≥ 20 bar for deep pockets) to prevent chip recutting.
- Depth of Cut: Do not exceed 3.2 mm axial depth in slotting without pecking or chipbreaker cycles.
- Speed Ramp: Start at 70% of recommended Vc and increase gradually to optimize tool life.
- Tool Inspection: Inspect cutting edges after 30 minutes of cut time. Look for coating flaking or edge chipping.
11. Toolholder Compatibility
| Holder Type | Compatibility | Notes |
|---|---|---|
| ER Collet Chuck (ER16-ER32) | ✓ Compatible | Ensure collet size matches shank diameter exactly |
| Shrink Fit Holder | ✓ Recommended | Best for high-speed machining; provides 3× grip force |
| Hydraulic Expansion Chuck | ✓ Compatible | Excellent damping for finishing operations |
| Milling Chuck (KM / HSK) | ✓ Compatible | Use for heavy-duty roughing |
| Side-Lock (Weldon) Holder | △ Caution | May cause runout > 10 µm; not recommended for finishing |
Shank Diameter: 3.18 mm (h6 tolerance). Use holder with matching bore and ≤ 3 µm TIR at 4×D projection.
