Machining materials that produce dust and fumes? We have just the solution for you!

A clear blue sky is over Breton machining centres. Protection is fundamental for the safety of the work environment:

but do you think this means doors? Wrong. 
Looking up can give us an idea of how chips, dust and fumes, some of which may be toxic, can be dispersed in the environment. That's why Breton mobile bridge machines like the Matrix, Flymill, Maxima and Eagle are fitted with full covers. 
The search for higher performance often pushes manufacturers to create rigid bridge machine-tools offering higher and higher performance, which at high speed can produce emissions. 



Let's take the Maxima as an example; it's one of the biggest machine-tools in the Breton range, and as a  consequence it has a large, light top cover that can be customized (in fact, the bellows constructions is modular), and it's always anchored to the bridge which follows its movements. 


The Matrix machining centre is often used to machine aluminium, titanium and steel, materials that can produce chips




While on the one hand customers want faster machines, on the other Breton has to make sure that in the upper covers, fast movements are silent and precise, instead of producing noise and vibrations. 
Thanks to the soundproofing material used to dampen the end-of-travel, the self-lubricating sliding blocks and polymer-coated metal rollers, there is no such risk
      


The Flymill is also used to machine resins, the dust of which can easily be sucked up by the bellows. To prevent this happening, all the covers installed on Breton machines have translucent fabric bellows (they look almost transparent and let light pass so you can see the machine working), with a very high resistance to abrasion, cutting, oils and high temperatures in general



Composite materials are also affected by these problems: in this case fumes and dust emissions. Without a doubt, the Eagle is the perfect machining centre for this type of process. 



The installation of the top bellows in this case prevents fine dust escaping, guaranteeing a controlled airflow so that the dust can be extracted

Manufacturing gears with the eyes of the designer

By Anna Bonanomi - Organi di Trasmissione
Gear production using 5-axis machine tools shows its full potential in the context of the increasingly small lots required, on the condition that the synergy achieved also includes a software environment and mechanical systems/hardware capable of optimal interpretation of the required specifications.
Manufacturing high quality gears with 5-axis machine tools calls for an essential and winning combination capable of balancing mechanical systems, software and process in order to meet designers' real needs. This is confirmed by Claudio Saurin, engineer and product development manager with Breton, a company based in Castello di Godego (Treviso - Italy) that has spent several years producing tailored machining centers featuring high technical specifications and evolved technology capable of delivering a highly competitive system in a market that is often faced with the need to produce increasingly small lots of parts. The reason lies in the fact that in this type of production (typical of medium/large size gears from 500mm to 3500mm) the tools required are frequently extremely expensive, hard to procure rapidly, etc.
Claudio Saurin continues «The ability for tooling machines capable of meeting the most stringent requirements in terms of accuracy and competitiveness expressed by gear designers and manufacturers calls for a high level of specialization. And it's essential to be able to offer the designer (especially the designer of bevel gear sets in the 400 to 1600mm range, which are perhaps still excessively reliant on tradition, ed.) a technically competent and convincing approach».
A conscious reflection, based on the experience that Claudio Saurin has accumulated during his work as a gear designer and that has been transformed into tangible innovation in the development of new solutions that touch on mechanical aspects and electronics, and that are especially focused on the process software. Just a few years ago an agreement was sealed between Breton and Kiss-Soft, a company with consolidated experience in the creation of specific software for gears and transmissions of all types, that has led to the implementation of programs, supplied on an exclusive basis (by Breton) and that allow the execution of machining processes that are impossible using conventional methods.

«Software – continues Claudio Saurin – that makes it possible, in bevel helical teeth for example, to machine the relief groove at the tooth root in the same way as it is created using hobbing cutters with protuberance on cylindrical teeth. Or to achieve refinements in the management of surface curvature in order to shift contact points by controlling the distortion of the surface in question rather than the settings on the machine. This involves making highly complex topological modifications».
At this point the transition to bring the surfaces generated by the afore-mentioned Kiss-soft software to the machine is managed by the Gear CAD and Gear CAM applications (developed by Breton using the Rhinoceros CAD engine and the RhinoNC CAM engine), which allow complete management of the process to create surfaces including chamfers, and of the associated machining operations.

Integrated process platform
«The technological synergy we have created – explains Claudio Saurin – allows the designer to develop the best material removal strategies and perform adequate simulations, allowing also the choice of the most suitable tool to create the tooth base until completing the workpiece after hardening. For example, to design a double helical gear the conventional approach is to design the left or right face and then make a specular design CAD, filleting and chamfering wherever necessary. In other words, our modus operandi is to fine tune the geometry as though we were the gear designer».
The greatest effort was therefore, on the one hand, that of creating an adequate design environment, and on the other hand to use machines that are able to optimize efficiency with high performance cutting processes.
«Not only – continues Claudio Saurin – but with the added value of a user-friendly and intuitive CAM system on board the machine. A process guided by a wizard that aids the operator in defining geometries and optimal tool paths. The decision is based on the fact that companies that manufacture exclusively gears and not the associated housings are generally unlikely to possess this kind of software».
In other words, the proposed solution is based on an integrated platform that includes a gear calculation code, a CAD application for generation of surfaces and a CAM application for the machining stage.

5 axes of quality for gears of various types
It is precisely to meet specific gear machining requirements that Breton has developed specific machining cycles to apply to its 5-axis machines, notably the Ultrix series model 1000 RT HD vertical machining center, which is particularly indicated for high speed machining of gears of diameters up to 1000mm.
«This is a high-speed machine featuring a high degree of automation – explains Claudio Saurin – designed and developed for milling, turning and grinding of workpieces of up to 1,200mm in diameter».
Equipped, in this version, with a powerful 75kW spindle with 300Nm of torque at 14,000 rpm and software for the production of helical bevel gears, this machining center can machine steel, aluminum, superalloys and composites. The machine features a monobloc structurewith gantry type travelling beam, with a 5-axis movement achieved by combining 3 linear axes with a rotary-tilting table. 
Gears can also be machined using various Breton machine models in the Maxima and Titan series (with large size gantry solutions and turning diameter). Systems that support an integrated process of turning, milling and hobbing pre- and post-heat treatment of medium and large size gears (up to 2,500mm for single piece parts).

«The know-how and experience acquired  – adds Claudio Saurin in conclusion – allow us to offer the designer a comprehensive set of tools construed in the broadest sense, including both software and process components. This makes it possible to use conventional 5-axis NC machines to design and produce a very large range of mechanical components rapidly and with superb quality results capable of guaranteeing a high level of competitiveness».

In other words, a new way of approaching the culture of gear manufacture. Not merely spur tooth and helical tooth gears, but also double helical cylindrical gears, spur tooth and spiral tooth bevel gear sets in accordance with the most common geometries, and also face gears for drive transmission between right-angle or non-parallel shafts.

The original business network

Andi-mec based in Ozzano dell'Emilia, with over forty years of experience in the field has become the centre of a business network, through entrepreneurial ideas and techniques.
One of these was choosing Breton machining centres.
(by Paolo Beducci)

There are some who are born to be entrepreneurs. I wasn't one of those though. I just ended up doing the job and as I had a family to feed, I accepted the role required. It was almost an obligation!”.
This is how Vittorio Grandi begins the story of his career and how he set up Andi-mec, the first company of a group with branches in Emilia Romagna and Romania, paving the way for new forms of partnership between entrepreneurs. 
Grandi's career started in the 70's. At the time he was a fitter and tester of machines and plants for one of the biggest packaging machine manufacturers. His job was to travel the world and get to work what had been designed and manufactured in Italy and exported all over the world. 

It wasn't easy," he recalls in his straightforward way, "I was a troublemaker, a fervent trade unionist. That's how I clashed with the owner of the company I was working for. Probably in order to try and eliminate a discordant voice, he decided to offer me the chance to set up a business on my own and started giving me the machines and plants they made to test and ship to the final customer”.

They must have realized that someone with a strong personality would want to push ahead and create something that went beyond daily routine. The first step towards change came in the early 1980's when Grandi bought two lathes and two milling machines from a company going bankrupt. 

At the time, there were lots of companies like mine with a pair of machines ready to be used for small jobs and adjusting plants being tested”.
For Grandi however it was a slightly different story. The two lathes and milling machines were often idle, which he didn't like. 
So I decided to go round drumming up some work for my four machines," recalls Grandi, "and see if I could find someone who knew how to use them”. 
Solutions can quickly be found to problems. Work started coming in and the machines, through the help of two ex colleagues who helped out in the evenings, produced parts at a healthy rate. At this point, obviously, things started getting interesting, so I set up another two companies with my two ex colleagues, producing parts for third parties in the machining industry. 

Things went well and the two companies grew, although industry in general and mechanical engineering in particular was going through a significant transformation at the time. Rather than machining and constructing everything in the one company, people were turning more and more often to outsourcing for a significant part of their machining requirements. For Grandi and co. this translated into an increase in the demand for finished parts and complex machining services.

Inevitably this meant considerable growth for Andi-mec and its subsidiaries, especially in terms of high-tech machining. This growth made Andi-mec a point of reference in machining complex parts. To keep up with business, Grandi bought new machine tools: machining centres, in particular.

The most interesting aspect in terms of industrial policy was the way Grandi created a network. This was only obviously possible thanks to the help of Grandi's partners over the years. Today, forty years after the first Andi-mec seed was sown, the group of companies in the small Dicoservice holding work with over 250 collaborators. A real business network that can therefore also offer its services to major players on an industrial scale always looking for solid and reliable suppliers.

But let's leave the strategy and economic choices aside for a while and focus on the technical aspects of the Andi-mec offer.
Obviously, if a company has managed to cut itself a niche in the market and remain in business for forty years, the entrepreneurial capacities and the quality of its work are irrefutable. 
Today the company from Ozzano dell’Emilia has a wide range of machines all of which were chosen with one goal in mind: quality, productivity and service, can all be found under one roof.

Today, Andi-mec can produce a single prototype, or a series of products for a wide range of industries in numerous applicative fields. These range from the railway to the aeronautical industry, but also include the packaging, automotive, energy, foodstuffs, pharmaceutical sectors and more.
What makes this possible is the correct mix of technological skills, organizational systems and productive integration. The combination of these elements guarantee the flexibility, speed and quality of a service our customers can count on.
The last machine purchased by Grandi for Andi-mec, was a Breton machining centre.

The reason we chose to purchase a Breton machine," says Grandi, "is because we want only machines based on the very latest technology. Today, having the latest technology is the only way to remain competitive. Also because," continues Grandi, technology gives us the space and time to guarantee the highest level of service without sending costs sky high”.
The Breton machine  installed is one of the top models of the manufacturer from Treviso, an Xceeder, a high speed vertical gantry-type machining centre, built using Metalquartz structural technology, with a rotary tilting worktable and direct drive. High workloads in a restricted space, high rigidity compared to a traditional arc-welded or polymer compound structure, are the strengths on the basis of which the Xceeder offers accuracy and operating stability second to none.

We went to visit Breton," continues Grandi, "and we realized it was a company that operates at the highest levels of excellence. So we took the plunge and bought the first machine, and we're very happy with it. We'll be purchasing another from Breton as soon as we can. 
The reason for this is not only because we're fully satisfied with the Xceeder we have in the workshop which works really well, it's also because we feel we've had the benefit of continuous support from the manufacturer who can assist us step-by-step at a time when something unexpected turns up, which is especially vital when dealing with the latest technology. Difficulties are something you have to get used to in this job
It's inevitable. So, instead of looking for the best price, or discount, or other more or less consistent promotions, I think it's important to deal with a serious company that realizes it hasn't finished its job as soon as the machining centre has been consigned and installed. Also in this sense, Breton in my opinion is a company of the future.

It's not a question of spending or saving a few thousand euros when you're already spending hundreds for the machine. The most important thing is that you're dealing with someone who's serious about their work”.
