Thanks to the double offset with respect to the RAM centre, Hornet allows machining of 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.
High dynamic 5-axis vertical gantry machining centre with modular structure
The wide range of structural combinations available makes it possible to create a bespoke configuration based on the required production volumes. The technical features make the machine ideal for high speed machining of parts with complex 3D shapes in lightweight alloy, resin, or composite materials.
- 1Total application flexibility
- 2Significant dimensional modularity
- 3Perfect for both wet and dry machining operations
- 4Temperature variations are under control
- 5Two different heads to cover all requirements
Dynamics and power for machining composites and aluminium
The structure, entirely in arc welded steel and sized in accordance with FEA processes, not only reduces vibration and limits torsional stress, it also provides the necessary stiffness to ensure precision and repeatability through time. The slender structure and powerful brushless motors allow the machine to reach high speeds with quick acceleration: 70 m/min in X and Y, 50 m/min in Z (encoders on all linear axes) with acceleration of up to 4 m/s2.
This machining centre is ideal for companies making aluminium moulds and dies or patterns in resin, carbon fibre, and composites, always operating rapidly and with optimal precision.

Thanks to the double offset with respect to the RAM centre, Hornet allows machining of wider workpieces with the same X and Y linear strokes, both with the tool vertical and with the A axis at 90°./ 01Hornet, unique design angle head
Eagle is built of arc welded steel throughout and sized using finite elements analysis to reduce vibration and limit torsional stress; this choice makes it possible to comply with the dimensional modularity requirement imposed by machine users, allowing Breton to customise the standard product easily to meet market demands./ 02Elevated modularity
Eagle is a gantry machining centre with tall columns and a balanced vertical axis and it uses heads with a symmetrical structure for uniform thermal expansions.
The thermo-symmetrical design makes it possible to reduce structural deformations and allow them to be corrected via software. The points that generate the most heat (such as the head, A axis, and motor spindle) are cooled, in order to reduce heat transmission to adjacent parts of the structure./ 03Thermo-symmetrical design
The carriage and bridge are equipped with high efficiency motors with Dual Drive technology. This solution guarantees high force for the most demanding operations exploiting the full power of both motors operating in the same direction. For higher precision work the preload value is increased to obtain the maximum accuracy. The Dual Drive system has lower current consumption than linear motors and it does not require dedicated cooling systems./ 04Dual drive motors
The ultrasonic cutting head provides the facility to cut honeycomb material without tearing or chipping.
The head is managed like a normal machining tool and accommodated in the standard tool store./ 05Compatible with ultrasonic cutting head
A countersink checking head managed automatically by the numerical control allows the real position of holes in the workpiece to be checked before performing countersinking operations.
The head reads the real position of holes in the workpiece by means of a touch probe or 3-point laser, to establish the exact coordinates before countersinking. Compared to a traditional probing cycle this solution greatly reduces the times and hence costs./ 06Countersink checking head
Allows in line energy recovery during braking, so there's no need to dissipate energy on the braking resistor./ 07Braking energy recovery
