Robotised finishing center

13 08 2014

Well known for its multifunctional machining centers (rotary transfer machines), Precitrame Machines SA is also a historical provider of high performance polishing machines. The company has just presented a concept of robotic linear transfer machining centers with features that open new perspectives in terms of finishing and polishing. Meeting with Mr. Vincenzo Bonavoglia, Sales Director of the company.

Under a relatively small footprint, the Cyberpolish 640 T can offer up to 5 online cells offering two workstations each. It is controlled through the new Cybermotion 5.0 that offers features never seen before as the high performance trajectory following and the simultaneous management of six robots.

Under a relatively small footprint, the Cyberpolish 640 T can offer up to 5 online cells with two workstations each. It is controlled through the new Cybermotion 5.0 that offers features never seen before as the high performance trajectory following and the simultaneous management of six robots.

The basic concept is simple, let’s imagine a working cell including a robot and two workstations allowing six or seven axes machining. Then let’s multiply these cells to create machines with two to five stations. Parts are gripped in holding devices that move from one station to the next. Thus, it is possible to implement a global chain of finishing (e.g. deburring, felting, polishing and brightening) within a single machine, and in one clamping.

Incomparable cycle time and flexibility
The logic of the sequential work on several stations (and therefore always with operations in hidden time) allows the achievement of extremely short cycle times. Compared with a conventional solution, the tests show gains of 5 times or more.

To gain steps of production?
Nowadays the quality produced by machining centers is steadily increasing and, depending on the part to be done, they can be directly loaded into the Cyberpolish T for all operations from grinding to brightening without having to pass through a specific grinding machine before. M. Bonavoglia says: “In some cases, specialised grinding operations before finishing are always necessary, but for all the others, we can directly finish the parts in one machine and in one clamping just after the milling operations”.

Precitrame will be present at the next AMB with a multifunctional machining centre that will perform an automotive part. The new Cyberpolish series T will be shown through the many multimedia tools of the company.

High quality material and total flexibility

23 06 2014

If L. Klein SA is a supplier of high-grade steel and material that innovates continuously and offers creative solutions to help its customers, it is also a company for whom the relationship with its users and its suppliers is of paramount importance. L. Klein SA has grown with the watchmaking sector and the regional delivery plan served by its trucks has been the same for 60 years! Meeting with the two directors, Olivier and Philippe Schiess.

In their premises of Bienne, L. Klein SA has a very large stock in order to answer quickly to all requests.

In their premises of Bienne, L. Klein SA has a very large stock in order to answer quickly to all requests. Deliveries are done worldwide.

Similarly, L. Klein SA has been working with some foundries for more than 30 years. The Directors tell us: “We have built long term relationships with our suppliers and this allows us to work closely for the development of new materials or new qualities”. Over the years, this partnership has enabled the realisation of products that would have been impossible to be created otherwise.

Quantities of delivery
“With us, no minimum quantity, if you need one single bar, it is possible” explain the directors. And it is also this flexibility that allows Klein to be recognised on the international markets. For example if you need a special material, it is often not possible to order less than 1000 kg elsewhere.

The article published in Eurotec addresses the following points:

  • Quality of delivery
  • A large stock
  • New gradations that bring more (for high precision machining and watchmaking)
  • It is necessary to take the plunge
  • Watchmaking has everything to gain
  • A bespoke service
Watchmakers are beginning to see the benefits of new materials such as the LW100X (using metallic powder technology). Like Christophe Claret that uses this material to create some parts of its exceptional watches.

New compact industrial technology

20 06 2014

At EPHJ Bumotec presents its new s100, a machining center with 3 linear axes and two machining spindles working alternatively.

The two 60'000 rpm motor-spindles and all linear axes allow the machine to be very efficient and reactive.

The two 60’000 rpm motor-spindles and all linear axes allow the machine to be very efficient and reactive.

This new concept allows the machine to reduce tool changes to the minimum as the changes are doing in hidden time on one spindle while the other is working. Every spindle has its own tool magazine (up to 36 in total).

A new concept in-between standard solutions
Nowadays the productions of parts for watch movements are usualy done using a batch of single spindle machines (mainly for small batches) or on large production chains on transfer machines for bigger series. This Bumotec s100 is aimed to propose an intermediate solution.

With its small size, its new design and the LED lighting, the first glimpse of the machine is impressive.

Chip to chip time is redzuced to the max as all tools changes are effectuated in hidden time.

EPHJ-EPMT-SMT starts tomorrow

16 06 2014

It is tomorrow in Geneva that this trade-show dedicated to watch industry, microtechnology and medical will open its door at Palexpo. We’ve met with André Colard and Oliver Saenger, the founders of the show, to catch the spirit of the event.
EPHJ1
If sometimes the distinctions between EPHJ (watchmaking), EPMT (microtechnology) and SMT (medical) are a little fuzzy in the minds of visitors, it is finally not very important; these three sectors work in close collaboration and synergies available to exhibitors and visitors are widely acclaimed.

Mixed fields
“At the beginning, some traditional watchmaking exhibitors blamed us to open the show to all microtechnologies, but this era is over and today the transfers of technologies and ideas between these areas is one of the strengths of the show” says Mr. Colard. Exhibitors are therefore in Geneva not only to conduct business, but also fetch new ideas and new technologies. In this state of mind, the show organizes theme days and conferences that not only add visibility to the event (and therefore very targeted visitors on the basis of the themes), but add value to the trips of visitors to Geneva. To guarantee the success, the organizers also ensure that exhibitors fit well in the concept of the trade show. Mr. Saenger says: “Sometimes we refuse exhibitors because their products are not in phase with the event and in this case, neither them nor visitors would be satisfied”.

The only Medtec trade show in Switzerland in 2014
Questioned about the SMT part and its relative smallness, the organizers are formal: “Indeed, the number of exhibitors located on this part of the exhibition, though expanding, is quite limited, but it is mainly because there are few companies working exclusively for the medical field. More than 100 exhibitors of the EPHJ-EPMT, announce to also work in medical technologies and many of them participate regularly to the medical exhibitions in Europe. As EPHJ-EPMT-SMT is the event covering every aspect of microtechnology, exhibitors are present, but perhaps less visible under the medical aspect”. They add: “In 2014 we are the only professional exhibition dedicated to medical technology in Switzerland”.

There are also many interesting talks, you can download the programme here.

Many news and skills to discover in Geneva, don’t miss them. You can download your free entrance ticket here.

Opening hours
From Tuesday to Thursday (June 17 to 19), 9:30 am – 6:00 pm
Friday June 20, 9:30 am – 5:00 pm
Palexpo Geneva

More options for surface finishing

5 06 2014

At the EPHJ trade fair, Recomatic/Bula Technologie will be presenting several new products which meet specific customer needs, particularly for watchmaking customers. A few customers have already seen some of these new products and were favourably impressed by what they saw. So much so, that the company has even sold several machines before the official launch at EPHJ. We went to Courtedoux to meet Mr. Marco von Gunten, who has been Sales & Marketing Manager for the last 3 months.

The MR480 is a veritable machining centre comprised of a very rigid frame and 3 independent spindles, thus ensuring a high degree of stability.

The manager is delighted to have the opportunity to be part of the launch of these new products, as he says straight away, “I am new in the company and three things never cease to surprise me: the high degree of innovation in the products, the fact that our customers’ needs are really taken into account and the motivation of our workforce”.

Increasing synergy
Since the company took over Bula in 2008, the Recomatic group has been working to provide complementary solutions to its customers in order to offer a complete service from the preparation of a surface from a geometric point of view to the finishing of the same surfaces in terms of appearance, including automation. The company will be presenting five new products at EPHJ.

The following products will be launched at the fair:

  • Reco-MR480 grinding and lapping machine
  • Reco-MS300 satin finishing machine and
  • Bula satin finishing module.

In terms of evolution, the company will be presenting the new versions of the automatic polishing machines Bula-Poligo B11 and B22.

Making the difference with surface appearance
All the solutions on offer from Recomatic and Bula aim to provide new functionalities in order to increase the global performance of the machine and meet the increasingly high requirements of their customers. Mr von Gunten concludes, “Today Recomatic and Bula have taken their company to a new level and are offering industrial solutions which are completely in the spirit of the times, in particular in terms of repeat precision and their high level of performance. I would like to invite all customers and anyone else interested to come and see our products in greater detail on our stands A57 + A63 at the event in Geneva”.

Ready for the challenge

27 05 2014

In the high-end watchmaking subcontracting sector, the constraints imposed on workpieces are very strict in terms of size, geometry and appearance, bringing tough challenges for manufacturers.
Cyberis
For many years, Cyberis has ridden this wave, with the company undergoing constant growth. It has also bought more than 20 production machines over the last two years, and plans to purchase several machines in the next few months. Interview in Bassecourt with Mr. Muriset, the young director of this dynamic company with a workforce of around 30.

Does this signal the end of cam-type machines?
Cyberis works with several different types of automatic turning machines, namely the Micro7, Micro8 and Delta numerical control models and 25 MS-7 cam versions. Mr. Muriset explains: “Although the operators are very versatile and able to work on cam-type machines, we are planning to replace our inventory of older machines”.

The quest for excellence
“We work for many of the major Swiss watch brands, in particular the very high-end names, and we can’t afford the slightest error. We simply aim for perfection”, explains the Director. Of course, this applies to bar turning machines, but also to the polishing department, the staff, the management system and the checking methods. The entire company is on a quest for excellence.

…by a dynamic team
All of the staff working to achieve excellence in Bassecourt are well aware of the stakes. Those we met identified fully with the company and were proud to be working for such prestigious customers. Mr. Muriset concludes: “We are a small, dynamic business working tirelessly to serve our customers. We have two objectives: to continue to build long-term partnerships with our existing customers and to develop our portfolio by attracting new customers”.

To be discovered at EPHJ in Geneva from June 17 to 20, 2014 on booth H24.
