Machine bed

The new BMX machine bed has been designed with a 45° slant, compared with 30° on the previous series.
The innovative design, the generously sized 45 mm roller guideways and the approximately 1,500 kg increase in machine weight provide greater rigidity and load resistance while significantly reducing vibration.

At the heart of the new BMX51/70 turret is a powerful integrated motor in the tool disc, thermally cooled and stabilized for maximum efficiency.
The motion is transmitted directly, with no kinematic chain: the motor is directly coupled to the tool holder.
The result? A simpler, more compact, high-performance system.
Main advantages:
- Drastically reduced vibrations
- No power loss or mechanical play
- Less heat generation
The final benefit is tangible: better finishes, greater rigidity and removal capacity, with quieter and more stable operation even during the toughest processes.

Turret with Integrated Motor: Power and Precision at the Core

BMX 70

The liquid-cooled synchronous electrospindles offer top-tier performance in torque, power, and speed.
Designed with high-precision bearings (ball and cylindrical roller), they ensure maximum rigidity and stability for every operation.
Thanks to the available torque even at low speeds, you can perform significant material removal without sacrificing quality: excellent roundness and flawless finishes, even on difficult materials.

Spindles

BMX 70

The new BMX51/70 sub-spindle, with CNC-controlled Z3 and X3 axes, adds a higher level of flexibility and productivity to the machine.
Thanks to its ability to offset from the main spindle, it offers clear advantages:
- Zero interference between the two work areas
- Simultaneous machining with three tools via Superimposition function
An advanced solution designed to optimize cycle times and fully exploit the potential of multi-process turning.

Sub-Spindle

Biglia Servo Turrets: Top-Level Performance and Technology

The two high-performance turrets, designed and manufactured by BIGLIA, feature 15 driven-tool positions each and can accommodate up to 60 tools. The box guideways on the X and Y axes provide greater stability during the most demanding machining operations.

Not only bar machining: maximum flexibility also for chucking operations

The new BMX51/70 is designed to deliver maximum performance in chucking operations, combining power, capacity and versatility.
Thanks to the possibility of fitting a 250 mm chuck on the main spindle and machining diameters up to 270 mm, the lathe delivers high performance even on large components.
A 210 mm chuck can be installed on the sub-spindle, further extending the finishing and chucking capabilities while maintaining the same precision and stability throughout the production cycle.

Machining applications

Our latest-generation machine tool performs a wide range of high-precision machining operations, both from bar and in chucking mode. Turning, milling, drilling and threading are handled efficiently and flexibly thanks to driven turrets, CNC-controlled axes and high-performance spindles. Ideal for producing complex and large components, the machine ensures stability, power and excellent surface finish even on difficult-to-machine materials.

Programmable automatic parts unloader

The finished-part unloading arm is CNC-programmable and allows parts up to 300 mm long to be unloaded automatically and in masked time directly onto the conveyor.
