■ Water-cooled worm gear for higher precision and elimination of thermal influences. ■ Higher swivel speeds for shorter overall machining times. ■ Clamping of rotary axes for greater rigidity during roughing. ■ Robust, reliable grease replenishment system to ensure long life and profitability.
Areas of application Ideal when a wide range of machining applications needs to be satisfied with a single head. Today rapidly changing tasks and machining conditions are typical and hard to plan for in advance: from high-precision machining of composites, via volume machining of aluminium to HSC milling strategies for steel and cast iron.
