Interchangeable head system — technical comparison
Architecture where only the cutting head is replaced. This page compares the Hanna HR® with the generic family of interchangeable head systems available on the market.
Interchangeable head systems dominate the European modular reaming segment. The head is attached to the body by a proprietary connection (HFS, CFS, BAYO-T, RX, etc.); the body remains in the spindle.
How the Hanna HR® is positioned
The Hanna HR® eliminates two steps that interchangeable head systems still require:
- No external preset — seat repeatability ≤ 3 µm guarantees direct re-entry.
- No zero reset — the offset saved in the CNC remains valid after the change.
Metrics under controlled conditions
| Metric | Generic interchangeable head family | Hanna HR® |
|---|---|---|
| Total change time | 2–5 min with preset | ≤ 25 s, no preset |
| Repeatability | ± 5–10 µm | ≤ 3 µm |
| Cost per edge | Reference | −30% |
| Performance (parts/h) | Reference | +10% |
| ESG (kg WC/100k parts) | Reference | +90% better |
