Biglia B1250

The new B750/B1250 series represents the “state of the art” of multifunction turning centers. The new turret with direct drive built-in motor is the heart of this range of machines. Available in 10 versions featuring 750 mm or 1250 mm turning length, this line of machines provides a wide spectrum of machining possibilities ranging from universal turning to complete machining of complex parts thanks to the CNC automatic tailstock, sub-spindle, rotary tools and C/Y axis. More accuracy Delivered by the rugged bed designed for higher heat stability, and the thermal stabilization of the main heat sources such as spindles, turret and hydraulic unit. More productivity Thanks to the massive rigid cast-iron machine bed and the flat hardened and ground slide-ways on all axes ensuring high rigidity and exceptional vibration dampening. The fast indexing, sturdy BIGLIA servo-turret, and the high capability of chip removal in both turn and mill operations are enabled by the new powerful servo motors.
