Multitasking to have all work phases performed on a single machine

The trunnion table is among the largest on the market

The Breton Ultrix series is ideal for milling and turning of medium-size/large workpieces in titanium, superalloys, steel, lightweight alloys, and special composites. Developed on gantry architecture with a gantry type moving bridge, the machine has a trunnion table and independent boring bar.

A machining centre for high speed milling and turning that delivers high performance with absolute precision while also being able to handle large size workpieces. With strokes of up to 1,700 x 1,700 x 1,000 mm and maximum swing diameter over the bed of 1,600 mm, the Ultrix E3 is our largest trunnion table machine. Painstaking attention was awarded to the layout during the design stage, with the aim of achieving the smallest possible machine footprint.

A perfect solution for the aerospace industry

Ultrix is the best solution for machining aero engine components: the vertical spindle facilitates workpiece positioning, the trunnion table gives better access and allows the part to be cleaned with ease and removal of chips by rotating the A axis.

Up to two angle heads can be housed at the rear of the machine, with fully automatic loading and unloading cycles. The head body is clamped hydraulically to the RAM to allow transmission of all the available motor spindle torque.

Easy access and maintenance

The top bellows open completely, facilitating workpiece loading/unloading operations with overhead cranes. The work area is fully clad in stainless steel to make it bright, easy to clean, and impervious to erosion caused by machining chips. All the axes are pressurised to prevent infiltration of contaminants. Accessibility has been significantly improved, allowing the operator within just 15 cm of the turning table.

Technological highlights

The machine is equipped with a series of high performance trunnion tables with Direct Drive technology.

/ 01

Trunnion tables with torque motors
Ultrix has a vertical boring bar rigidly connected to the vertical RAM structure, with position control and, thanks to powerful hydraulic brakes it can be locked at any point of its vertical stroke.

/ 02

Dedicated boring bar
The base frame is made of Metalquartz to impart the maximum stiffness and stability, providing the operator with the best ergonomics and comfort for easy and safe access to the machine.

/ 03

Metalquartz base frame
Also the electrical cabinets and maintenance area has been optimised. The hydraulic power and pneumatic control units are grouped together in an orderly and compact manner, ensuring all modules involved in diagnostics and maintenance are easily accessible. Designed with modularity and scalability in mind, this system offers the potential for future machine upgrades with new accessories/automations.

/ 04

Optimised maintenance corner
Breton Ultrix can accommodate several types of tool stores, all of which fully compatible with the new high-speed compact tool changer. This solution, which makes use of a reduced opening in the machine column, makes it possible to maintain the maximum structural stiffness with a wide choice of possible tool store positions.

/ 05

Tool changer incorporated in the column
Breton Ultrix was designed using the full potential of digital twin techniques. All machine characteristics were entered in a virtual space to create a realistic simulation and assess performance in various operating scenarios. The result is a structure built according to simulations allowing targeted optimisation and raising performance levels.

/ 06

Digital Twin
A clean machine lasts much longer. That's why we clad the work area with modular stainless steel panels, which are easy to clean and retain their properties through time, despite being constantly exposed to dust and chips.
