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
The B750 range of machines is equipped with liquid cooled built-in motor spindles. Available with bar capacity of 70 or 102 mm, the integral motor-spindles are driven by powerful (22/38 Kw) and high torque (286/1014 Nm) motors, available at low rpm.
Also, the combination of the roller and ball bearings allow superb chip removal rates as well as exceptional surface finish and roundness accuracy.
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).
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.
