The 5-axis machining centres from the HF series are optimally equipped to meet the exacting requirements of modern production processes. Enabling 5-sided and simultaneous 5-axis machining, they allow you to handle many different tasks on a single machine. Highly productive and flexible, with easy operation and maintenance, available with pallet changer or table loading. Key facts _horizontal 5-axis machining centres with pallet changer   or table loading _universal machining centres with 5th axis in the   workpiece _swivelling NC rotary table with counter bearing and   AB kinematics with highly...

Machine concept Perfect balance of rigidity and dynamics The HF series 5-axis machining centres are the perfect combination of apparent contrasts – stiffness and dynamics. The basis is the rigid machine bed. Highly precise and fast machining cycles guarantee the unique machine structure of the HF: the fifth axis is located inside the workpiece, the directly-driven A/B-axis is supported by a counter bearing. 3 2

Machining units The right spindle for every task 5-axis machining requires all components of a machining centre to deliver a top performance. The spindle must be particularly efficient: highly flexible, with torque characteristic curve adapted for the task in hand and suitable for a range of materials. The HF series 5-axis machining centres offer seven robust and powerful versions, so you work with a spindle that best suits your requirements. Standard: SC 63 i 1) Mill-Turn: HSK-T 2) Cycle time 2 min 3) Cycle time 5 min
