Cutting edge technology and unequalled productivity.

Machine configurations The new B750/B1250 series represents the “state of the art” of multifunction turning centres. 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...

Great versatility and superb chip removal.

Both B1250 and B750 machines are equipped with the same turrets and X /Y slides. The B1250 is particularly suitable for the machining of long shafts. This machine features a long bed with a longitudinal stroke of 1310 mm and a sturdy CNC automatic tailstock with a 115 mm hydraulic quill. The B1250 can accept two versions of automatic steady-rests: “in-cycle” version with positioning by the Z-axis slide; “travelling” version operated by the axis motor. Thermal stability To minimize dimensional changes and maintain the accuracy in the long-run, the temperature of the main heat sources...

Servo-turret with built-in motor. New Biglia servo-turret with direct drive. The quick BIGLIA 12- or 16-station servo-turret (index time 0,3 sec.), featuring a large HIRTH coupling (230 mm diam.), can accept up to 34 tools that can work simultaneously. The new live tooling system is the main feature of this new turret, with the rotary motion being transmitted by the built-in motor, integrated in the tool plate, directly to the rotary tool. * Max. spindle speed limited to 6000 rpm by standard rotary tools.

Live tools Live tools This new turret equipped with a cooled direct drive built-in spindle motor (10-17,5 kW - max. 10000* rpm) to drive the rotary tools represents the main feature of the new B750/B1250 series. The kinematic chain has been eliminated. The motion is now transmitted by a direct coupling between the integrated motor and the rotary tool. The main advantages are: - REDUCTION OF VIBRATION DAMPENING - ELIMINATION OF POWER LOSS AND MECHANICAL PLAY - REDUCTION OF HEAT This innovative concept ensures high rigidity, exceptional surface finish, superb chip removal and restricted...

Spindles The B750/B1250 range of machines is equipped with liquid cooled built-in motor spindles, with the exception of the B1250, this machine comes with the standard spindle configuration. Available with bar capacity of 65 up to 102 mm, the BIGLIA integral motor-spindles are driven by powerful (22 to 38 kW) and high torque (286 to 1014 Nm) motors. Also, the combination of the roller and ball bearings plus the high torque and power range available at low rpm allow superb chip removal rates as well as exceptional surface finish and roundness accuracy.

Sub-spindle The work-piece is automatically transferred from the main to the sub-spindle to allow the complete machining process on both sides. The sub-spindle is equipped with B-axis load detection system and pneumatic ejector to check presence of the component (option) which allows you to perform safe machining operations. Tool-setter (option) This device makes tool-setting simple, fast and accurate. The tool tip is brought into contact with the probe and the tool offset value is automatically stored into relevant table of the CNC control. It includes the automatic parts-catcher to unload...

Wide range of equipment and optionals. Tailstock with hydraulic quill (B1250). (standard feature on base, M and Y models) Both B750 and B1250 range of machines are equipped with the tailstock body that slides on flat slide-ways. Positioning is fully automatic. On the B750, the tailstock is operated by a servo motor and ballscrew (B axis). This solution improves operating flexibility since position and thrust are CNC-controlled. It can also be used to perform simultaneously both drilling and turning (option). On the B1250, the tailstock is positioned by the turret-holding carriage (Z-axis)....

Automatic steady-rest (option on B1250 only) The automatic and self-centre steady-rest is suitable for shaft ranging up to 240 mm diameter. Positioning as well as opening and closing of the arms is programmable. The steady-rest can be single or double and is available in two versions: - in cycle” version with positioning by the Z-axis slide, “ - travelling” version operated by the axis “ motor. The movement can be synchronized or independent from the Z-axis s
