Breton Hawx is delivered preassembled with a prewired electrical cabinet. Once the customer has positioned the machine, only the front housings remain to be fitted. The entire assembly and start-up procedure takes just 5 days: in the first 3 days the machine is unloaded, anchored, and completed, start-up takes place on day 4 while day 5 is reserved for training. Hawx can be easily relocated on the customer's site to accommodate possible changes to the production layout.
High-dynamic 5 axis vertical gantry monobloc machining centre
The right combination of robustness and stability makes the machine ideal for milling and trimming operations at high speed on parts with complex 3D shapes made of lightweight alloy, resin, or composite materials.

- Robustness and stability over time1
Robustness and stability over time
The monolithic load-bearing structure and bridge-carriage-RAM unit with box-in-box architecture were designed to raise the level of accuracy and repeatability through time while maintaining high levels of acceleration and speed.
The end result is the creation of a new and clearly superior benchmark for machining centres in this category.
The Hornet head developed by Breton for this machining centre is extremely stiff to ensure greater accuracy on the part most sensitive to stress, even for the most demanding machining work.
- Unbeatable footprint ratio2
Unbeatable footprint ratio
Up to 29% more work area for the same external dimensions.
Thanks to its ultracompact design, Hawx provides higher machinable volumes in the same space compared to its main competitors. With external dimensions of just 6,300 mm x 3,150 mm, the machine can provide a 4,200 mm x 2,100 mm work area with vertical oriented spindle, and 3,780 x 1,680 with spindle at 90°. This was enabled by optimising the box-in-box structure and thanks to the offset of the new Hornet head.
- Perfect for both wet and dry machining operations3
Perfect for both wet and dry machining operations
Failing to provide correct management of dust, chips and liquids generated by various work processes means exposing the operator to risk, creating a hazardous workplace, increasing downtime and impairing machine performance. Hawx is designed to operate both wet and dry without any problems of this type.
A series of safety systems was included to protect the most sensitive parts. The axis guides are securely protected by bellows and the main drive train components are pressurised to prevent the ingress of contaminants. The machine is also equipped with top bellows to keep dust inside the work area and well away from the guides.
Also the Z axis recirculating ball screw is enclosed and fully protected. Apart from a labyrinth seal, the head has a V-ring wiper seal for complete protection when working with aggressive and abrasive materials and during operations with coolant. The tool magazine, located outside the work area to protect the tapers, enters only for the time strictly necessary for each tool change.
- Safety at the next level4
Safety at the next level
Breton Hawx is equipped as standard with a Safety Integrated system, including an additional brake on the Z axis to prevent it from falling. All servo systems and pneumatic actuators protected by safety valves and contacts.
The integration of top-class components allows operations to be performed with open safeguards, such as tool verification and workpiece checks with the spindle moving at low revolutions, in complete safety.
The ECO collision avoidance system prevents accidental impact between machine parts, not only automatic cycles but also during JOG movements
- High energy efficiency and reduced operating costs5
High energy efficiency and reduced operating costs
The aim is to maximise ROI, taking into account the entire life cycle of the machine.
The use of Murr low-consumption modular system eliminates hydraulic oil, pumps, heat exchangers and valves. It allows simple and quick replacement of sensors or installation of additional sensors, thus reducing service time and costs.
Maintenance costs are reduced through use of the VCS Rotary package, which checks and auto-calibrates the machine. Protection of servos by means of bellows and pressurisation makes it possible to increase reliability and extend the working life of components, while for wet solutions the use of self-cleaning or consumable-free filter systems greatly reduces machine downtimes and extra costs for filter replacements.
- Breton reliability and assistance6
Breton reliability and assistance
Service is a core aspect of all machining centres. Speed of response, technical expertise, punctuality of service and fast shipping of spare parts are hallmarks of the Breton brand. This level of service, combined with informed technical choices, such as the insistence on high-end components and the Teleservice system, mean Hawx delivers the very highest availability rates.
The robustness and repeatability that was lacking
Built to exceed the usual limitations of its category: reduced robustness and poor repeatability in time.
Thanks to the optimised design, Breton Hawx is stiffer and more stable while also guaranteeing an excellent size to work area ratio. The machine can be easily inserted in all types of workshops as it arrives already assembled and tested; it does not require special foundations and start-up times are reduced to the minimum.
The arc welded monolithic load-bearing structure is the core of the machine, imparting robustness and allowing easy handling.
The unique nature of the box-in-box architecture guarantees a marked increase in stiffness of the bridge-carriage-RAM unit and combines with the high strength of the new Hornet head to greatly increase the rate of removal and accuracy, all with the maximum dynamics.
The innovative offset geometry of the head also makes it possible to increase machinable volumes while minimising the machine's outside dimensions, simultaneously improving access to the workpiece.
Heads available on Hawx
Spindles that can be installed on Hornet
- / 01Designed for delivery fully assembled
Hornet, thanks to the double offset of the A axis with respect to the RAM centre, allows you to machine wider workpieces with the same X and Y linear strokes, both with the tool vertical and with the A axis at 90°.
The generous rotation of the A axis (-105° +135°) enables undercut machining, reducing the need to reposition the workpiece, with a consequent increase in precision and elimination of a second set-up phase./ 02Hornet, unique design angle head
There are several work table set-up solutions available: flat table with threaded holes, vacuum table, table with with mesh gratings and collection bins./ 03Several work table solutions
The automatic 8-cell tool store, placed outside the work area, makes tool loading/unloading completely safe for the operator, with no need to suspend the work cycle. Thanks to the solution's modularity, capacity can be easily increased up to a maximum of 64 cells./ 04The intelligent tool store
The box-in-box architecture of the bridge-carriage-RAM unit guarantees an increase in stiffness to achieve greater accuracy and repeatability through time, also in heavy duty machining operations./ 05Box in Box Architecture
Allows in line energy recovery during braking, so there's no need to dissipate energy on the braking resistor./ 06Braking energy recovery
