Hard turning
Horizontal hard turning up to 500 mm
Vertical hard turning up to 1500 mm
- Higher flexibility with only standard tooling.
- Cost saving because of need of fewer process steps and set-ups
- Environmental friendly because of dry machining.
- High rigidity and dynamic stiffness
- Higher accuracy and better roughness than a universal lathe
- Low maintenance
- High process reliability due to integrated measuring units
Material
- Hardened steel
