10. Operating Guidelines
- Coolant: High-pressure through-spindle coolant (70+ bar) recommended for optimal chip evacuation and tool life
- Rigidity: Ensure minimal tool overhang. Use shortest possible toolholder and minimize stick-out
- Runout: Maintain TIR < 0.01 mm at tool tip for best performance and surface finish
- Entry: Use helical or ramp entry for pocketing operations. Avoid direct plunge with solid carbide endmills
- Chip Load: Start at 70% of recommended feed and increase gradually based on chip formation and sound
- Tool Life: Monitor flank wear (VB). Replace when VB > 0.2 mm or when surface finish degrades
- Storage: Store in original packaging. Avoid contact between cutting edges to prevent chipping
11. Toolholder Compatibility
| Toolholder Type | Shank Diameter | Clamping Method | Recommended For |
|---|---|---|---|
| Hydraulic Chuck | 0.5625" | Hydraulic clamping | High precision, vibration damping |
| Shrink Fit Holder | 0.5625" | Thermal interference fit | Maximum rigidity, HSM applications |
| ER Collet Chuck | ER16 / ER20 / ER25 | Collet clamping | General purpose, cost-effective |
