Future is unpredictable, that’s why we go Multitasking

We interviewed Ludwig Henkes, Managing Director of Capaul.

Which are the main reasons why you chose Breton? 

Breton gave us support right from the beginning helping to identify the most proper technical solution, customizing a proven product according to our needs.
The availability of a local support by Breton (Tecmo) eased this definition process and gave us the confidence that in any moment we will be able to trust on a competent and quick partner.

Which criteria were the key ones to drive your choice on MAXIMA 2000? 
Our company believes in the future and invests continuously on the development of its business, setting no limits to its applications.
For this reason we were looking for a solution granting high versatility, productivity, responding not only to today’s demands but also capable to give us the flexibility to adapt to a rapidly evolving market.
We focused since the beginning on mill turn machines, as they clearly better accomplished to the above requisites.

We wanted a very rigid and precise machine with wide working areas that could also reduce setup times.

With the help of FRAUNHOFER Institute and RWTH Aachen we submitted the shortlisted machines to severe tests of rigidity, precision and frequency response.
At the end of these analyses it was fairly easy for us to confirm MAXIMA as the best choice.

What are you expecting from the partnership with Breton? 
We look forward to seeing the same professionalism and expertise demonstrated in the first phase to be confirmed in the years ahead.
Breton represents for us not only a quality supplier but may act also as a commercial partner through which we are already increasing the visibility of our brand on the market and we expect to further develop our sales.

Breton Open House 2012

We perfectly know how important it is nowadays to be competitive, to make the most of the challenges the ever-demanding market throws down each day.

To do so, it's essential to use modern high-tech production systems, and keep constantly up-to-date with the latest technological developments.
It will therefore be an honour for me to welcome you on the 5th, 6th and 7th of July to show you some of the latest, interesting innovations in our works, with machining cells running specific applications for the aerospace, energy, automotive and transmission sectors. 16 installations, each with a high level of customization and the most innovative, efficient accessories.
For me, and the rest of the Breton staff, it will be a pleasure to welcome you.
Best regards
Luca Toncelli
President of Breton Spa

Don't miss:
Special materials such as carbon, resins, and fibres require specifically configured machines like the EAGLE range of machining centres, examples of which will be on show with fully-functional machines and detailed structural views.  

The XCEEDER 900RT 5-axis trochoidal machines also offer a solution for increasing productivity and reducing consumption.  

The reduction in setup times makes all the difference. You won’t believe how fast it is to change pallets on the FLYMILL gantries, the compact XCEEDER 900 RT, or how efficient it is to change the tool automatically on the ULTRIX 800 RT lathe-milling machine.

Not only is there a reduction in setup times, but also an exceptional increase in part accuracy and flexibility as on the MAXIMA 2000 K60, the big 5-axis turn-mill gantry.   

There have been new breakthroughs in the machining of gears and transmissions, thanks to the new Breton technological packages, which you'll be able to see at work on 2 ULTRIX 1000 RT machines.  

What's more, we'll be presenting the new version of our best seller, the MATRIX machine, a true evolution in design and performance.

Breton MAXIMA - Multitasking vertical machining centre (part 1)

Specifically designed and developed for demanding markets, Maxima performs to its best in terms of precision and productivity combining 5axis milling with turning. Thanks to a design that offers interesting possibilities to users, first of all pendulum machining while carrying out turning and milling operations.

Maxima is a machine developed from the experience gained by Breton with other models, from which it has taken the best that they could offer. Breton engineers have started from a heavy structure gantry machine, then adding a turning table and a head change system able to manage both the milling and the turning process at best.

It is really a machine with double possibilities because, besides relying on a modern milling machine, thanks to the head change it is possible to carry out also turning operations (even heavy) without stressing the components exclusively designed for milling.

Solid and stable

Starting from the structure, electrowelded steel,  coupling the steel with an optimized geometry it is possible to obtain the correct sizing of each component of Maxima.

But not only: the inside of each module is filled by an engineered granite patented by Breton, MetalQuartz, which offers interesting properties. First of all, it contributes in the vibration dampening, consequently increasing the stability and the quality of machined surfaces. Besides, this composite silicon-quartz material owns the same thermal expansion coefficient as the structure steel.

Milling and turning

Maxima is sold in different versions and configurations. The most evident element is the Y axis travel that, as above mentioned, can vary depending on the purchaser’s requirements simply adding other modules during its manufacturing.

Another value that characterizes each machine consists in the turning table diameter: we start from the smallest, with 1,200 mm diameter, up to 3,000 mm of Maxima 2500, passing through the 1,600 mm version.

The smallest tables are operated by direct drive, while with bigger diameters traditional motors in dual drive configuration are used. In this way it is possible to reach different speeds, torque and powers, suitable for specific uses.

The version with 3,000 mm diameter guarantees the maximum power of 100 kW, 116 kW in S6 at 40%, and a torque of 20,000 Nm (24,600 Nm in S6). With such characteristics, the 230 rpm that the motor/transmission group can offer is more than eough to machine with high peripheral speeds and heavy stock removals, like a real vertical lathe.

Besides, when it performs a turning operation the Gantry axis and the Z axis are kept in position by a set of hydraulic brakes, ideal for assuring the best statics of the structure without putting engines under strain.

Breton MAXIMA - multitasking vertical machining (part 2)

Heads and tools

The machine uses different tools for multitasking operations.

While the head used in turning is relatively simple, a model with Capto C8 taper, the milling one is certainly more complex.

The coupling with the ram is guaranteed  by a Hirth crown assuring the correct and constant positioning of heads and removing the risk that the efforts – especially in turning – are concentrated on the components dedicated to milling. Machines of this type are expected to machine for several years without needing extraordinary overhauls determined, for instance, by excessive stresses on parts not designed to bear them.

 

Maxima 2500 HD is characterized by the innovative head Tornado HD. This name hides a head with torque motor on the C axis that eliminates backlashes, permitting to achieve precisions in the volume of few hundreds on the five axes and enabling to reach 100 rpm. The flexibility is guaranteed by the fork-shaped configuration with non-coaxial spindle and big roughing power. Besides, the high-frequency electrospindle permits to operate effectively in milling (roughing and finishing) on steel, light alloys and alloys resistant to heat (used in some of the outlet application sectors of this machine, such as aerospace and military).

The change system provides for apposite niches in the structure where replacement heads are housed.

A further option offers the possibility of replacing the spindle cartridge only: in this way a single head can house, for instance, a motor suitable for roughing and a high-speed electrospindle for finishing.

Tornado HD 300/14 is the standard head proposed on Maxima: with a maximum power of 75 kW and a spindle torque of 300 Nm, it is proposed as solution able to meet successfully most requirements expressed by customers. It can reach in fact 14,000 rpm and house tools with HSK-100A taper.

 

Tools are housed in a wheel-type magazine that, in the change phase, is introduced into the machining field through an apposite panel. A variable number of tools, ranging from 20 to 30, can be housed, depending on their size. As an alternative, a rack with 60, 100 or 150 pockets can be installed, with a shuttle for the tool recovery and an arm that physically carries out the exchange. In both cases, the machining area is perfectly free and completely available for the piece positioning, allowing the movement of the head in the space without constraining it with the presence of tools or tool/head change equipment.

 

The secret of precision

Maxima has been conceived to satisfy very exacting demands in terms of productivity and precision. We have mentioned the capability of reaching a volumetric precision within 5 hundredths but it was not easy to attain these results.

 

The stable and stiff structure certainly contributes in essential way but it was necessary to do more: besides the air pressured optical scales, equipping both sides of the machine and the Z axis, and the encoders on rotary axes, the machine is provided with a balancing system for the compensation of the head and ram weight.

In this way, the only forces that affect the structures are the machining ones, widely within design parameters.

The “universal” mission of Maxima guarantees the possibility of machining a big number of materials, such as steel, aluminium, resins, titanium and carbon fibre. For the latter, in particular, they have studied suitable solutions for assuring the constant operation of the machine. First of all the upper part can be closed with bellows that do not limit the possibility of loading pieces with the crane but that, in presence of carbon fibre dust, isolate the machining area and do not allow the removed particles to go out. Moreover, all sliding and supporting surfaces are protected by a standard pressurization system.
