BIGLIA B658/B CNC turning center

BIGLIA B658/B CNC turning center was built in 2009 in Italy by OFFICINE E. BIGLIA & C. S.p.A. The machine, designed for machining workpieces with a maximum diameter of 380 mm, offers excellent precision and repeatability of the produced parts. The machining process is performed inside a large workspace which includes, among others, a powerful spindle, a 12-position turret and an automatic tailstock. All parameters are, in turn, entered in an intuitive FANUC CNC control with many useful functions. The BIGLIA B 658/B CNC lathe weighs 5700 kg.
