This machine is specially designed for the machining of print cylinders (max. Ø 800 mm; max. 2000 mm long). Machining comprises turn-milling of the lateral area, channel-milling and drilling. The outstanding features of the machine are high precision, high thermal stability and excellent damping characteristics.
The heavy HSK 160-main-spindle-unit (150 kW) is mainly used for turn-milling and channel-milling. This unit is equipped with a 14-slot disc-magazine. The dynamic HSK 100-ram unit (50 kW) is mainly used for drilling. This unit is equipped with a 40-slot oval-magazine. Each tool change is carried out by means of a twin-gripper.
The centering- and clamping units (X1- and X2-axes) are travelling separately during load- and unload- operation. During machining, the X-axes are electronically coupled. The rotary axes (A1 and A2) are driven both-sided and are also electronically coupled.
