*Spindle speed calculated for 0.055" diameter. Adjust based on actual machine capability and workpiece rigidity.
Operating Guidelines
- Runout: Maintain tool runout below 0.01 mm at the cutting edge to prevent uneven wear and premature failure
- Coolant: Use high-pressure coolant (70+ bar) directed at the cutting zone for optimal chip evacuation and thermal management
- Ramping: Maximum ramp angle 2° for full-width engagement; use helical interpolation for pocket entry
- Plunging: Center-cutting enabled; reduce feed to 50% for direct plunging operations
- Tool Life: Monitor flank wear (VB max 0.2 mm); replace when chipping or coating delamination is observed
- Storage: Store in original packaging at 15-25°C with <60% relative humidity to prevent corrosion
Toolholder Compatibility
| Holder Type | Specification | Compatibility | Notes |
|---|---|---|---|
| Collet Chuck | ER11 / ER16 / ER20 | Full | Use high-precision collet (≤5 μm runout) |
| Hydraulic Chuck | HydroForce Mini | Full | Excellent damping for long overhangs |
| Shrink Fit | Induction shrink fit | Full | Best rigidity and concentricity |
