B750

Universal turning centres

The main advantages of these machines are the box-type guideways on all axes and the new turret with the rotary motion being transmitted by the built-in motor, integrated in the tool plate, directly to the rotary tool.

 

Exceptional rigidity and high torque: top efficiency even in the heaviest machinings

The B750 range of machines is particularly suitable for universal turning and the complete machining of complex parts.

 

The main features of the B750 series are:

The massive rigid cast-iron machine bed that ensures exceptional vibration dampening thanks to the box-type guideways on all axes.

The new synchronous liquid cooled integral motor spindle allow unequalled power and higher spindle speed. Also, the combination of the roller and ball bearings allow powerful cutting as well as exceptional finish and roundness accuracy.

The 16-station servo-turret and the rotary tools with direct drive

The automatic tailstock - B-axis - improves operating flexibility since position and thrust are CNC-controlled

The synchronized sub-spindle is equipped with a parts ejector featuring collet cleaning system and sensor to detect that the finished part has been ejected

Main and sub-spindle with C-axis

The new Biglia servo-turret with direct drive

The new 16-station servo-turret 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 series.

Reduction of vibration dampening

Elimination of power loss and mechanical play

This innovative concept ensures exceptional surface finish, superb chip removal and restricted noise
