8. Application Map by Operation
| Operation Type | Suitability | Notes |
|---|---|---|
| Slotting (Full Width) | ★★★★☆ | Up to 1×DC depth recommended |
| Profiling / Side Milling | ★★★★★ | Optimal performance at 0.5-0.7×DC radial engagement |
| Pocketing | ★★★★★ | Excellent chip evacuation in enclosed pockets |
| Plunge Milling | ★★★★☆ | Center-cutting capable; reduce feed 30% |
| High-Speed Finishing | ★★★★☆ | Good surface finish; use 6-flute for mirror finish |
| Trochoidal Milling | ★★★★★ | Ideal for high-efficiency machining with low radial engagement |
9. Recommended Cutting Conditions
Values are starting recommendations. Adjust based on machine rigidity, workpiece fixturing, and coolant application.

10. Operating Guidelines
- Runout Check: Ensure spindle runout is below 0.01mm for optimal tool life and surface finish.
- Tool Overhang: Minimize overhang to ≤3×DC. Use shrink-fit or hydraulic chucks for best results.
- Entry Strategy: Use ramp or helical entry for pocketing operations. Avoid direct 90° plunging except with center-cutting tools.
- Coolant: Maintain consistent coolant flow. For heat-resistant alloys, consider high-pressure through-spindle coolant.
- Chip Evacuation: Ensure adequate chip evacuation, especially in deep pocketing and slotting operations.
- Tool Inspection: Inspect cutting edges before each use. Replace at first sign of coating wear or chipping.
- Speed/Feed Adjustment: Reduce cutting speed by 15-20% when machining hardened steels (>45 HRC).
11. Toolholder Compatibility
| Toolholder Type | Compatibility | Recommended For |
|---|---|---|
| ER Collet Chuck (ER16/ER20/ER32) | ★★★★☆ | General purpose; ensure proper torque |
| Shrink-Fit Holder | ★★★★★ | High-speed machining; best runout control |
| Hydraulic Chuck | ★★★★★ | Heavy roughing; excellent damping |
| Milling Chuck (Power Chuck) | ★★★★☆ | General milling; good grip force |
| Weldon Flat Holder | ★★★☆☆ | Side-lock only; higher runout risk |
