During the Journées Horlogères open days (March 3 to 6, 2015), Tornos will unveil a complete overhaul of these iconic machines. We met with Massimo Tidei, project manager, and Philippe Charles, product manager, both of whom work for Tornos.

The fastest machines on the market
“EvoDeco machines are equipped with the best kinematics on the market: no other current solution is able to offer the same level of performance and sophistication as an EvoDeco. It was of crucial importance that we kept ahead of the market in this way, as it is vital to Tornos and to our customers, who need to be the best in their field! The performance of our machines is mirrored by the success to our customers”, notes Philippe Charles.

Fundamental improvements
“In fact, since the trend is towards a reduction in the size of production runs, it is increasingly important that the first parts are perfect. The machine’s thermal system must therefore comprise the shortest possible loops to reduce the warm-up time as much as possible”, Massimo Tidei explains. The machine has also been redesigned in terms of rigidity to ensure it offers improved machining performance. The two new EvoDeco machines are also equipped with cyclical lubrication.

Two machines, 4 versions
Available in versions with 10 or 8 linear axes, EvoDeco 10 and EvoDeco 16 machines take two C axes as standard. The two turning machines are equipped with synchronous motor powered spindles. This technology, unique on this type of machine, means that the machine’s productivity can be increased significantly when machining parts which require frequent spindle stops. The cycle time is reduced by more than 30%!

Many possibilities
In addition to its highly comprehensive equipment, the EvoDeco 16 machine can, for example, be equipped with a B axis for positioning in back operation, which is particularly useful for creating angled implants for the dental industry. The EvoDeco 10 machine, however, can receive up to 3 hobbing devices, one of which can be used in back operation, making it without doubt the fastest hobbing machine on the market!

A hotly anticipated event

14 01 2015

Every year, a few weeks before Baselworld, specialists in watchmaking machining come from Switzerland, southern Germany and France to attend the Tornos Journées Horlogères open days, where they are able to discover new products, get advice and make purchases. In 2015, this hotly anticipated event will take place at the company’s premises in Moutier from March 3 to 6.

jhtornos

Brice Renggli, marketing manager, explains: “During the event, we present complete watchmaking solutions and all of our specialists are on hand to chat with customers. This allows us to offer customised solutions while consolidating our expertise in the field – it’s a win-win situation.”

A range dedicated to watchmaking solutions
Tornos has been supplying solutions to the watchmaking industry since the start of the last century, and its machines are most likely present in the vast majority of bar turning workshops producing components for this sector. Around 20% of Tornos’ turnover currently comes from this industry, and the company uses machines adapted for watchmaking to resolve its customers’ problems. Let’s take a look at some of the products:

SwissNano
“The SwissNano is used by many of our watchmaking customers, and has become an important machine for them thanks to its high precision, ergonomics and ability to produce 80% of the components found in a watch movement”, reveals Mr. Renggli. This small machine designed by Tornos has a surprising capacity for maintaining dimensional precision during production. The manager continues: “We knew that the machine had a good pedigree, but the results reported by our customers have strengthened this positive impression even further.”

EvoDeco 10
During the Journées Horlogères open days, visitors will be able to discover the new version of this well-known machine. “The machine can be equipped with three hobbing systems, which means we can produce the most complex watch parts,” adds Mr. Renggli. One distinctive aspect of the Journées Horlogères open days is that the exhibited machines are all running, and the company’s commissioning technicians are on hand to discuss their various features. On the subject of the EvoDeco, Mr. Renggli concludes: “For customers wanting to produce larger diameter parts such as the balance, we also offer the EvoDeco 16.”

MultiSwiss
For high-volume applications, the company has offered the MultiSwiss since 2011, to the satisfaction of the manufactures. The proof? The major watchmaking groups rely on the characteristics of this machine. In the words of Mr. Renggli: “We can perform hobbing operations and the machine also has a Y axis.” For example, the MultiSwiss machine can be used to finish parts such as barrel drums and arbors, and customers have also been delighted with the geometric and dimensional performance in these operations. The manager adds: “The characteristics of the MultiSwiss, in particular the hydrostatic technology, allow us to create finishes that satisfy watchmakers’ requirements.” The machine has been used to replace a set of cam-controlled turning machines with hobbing machines. The footprint and repeatability gains are unparalleled.

Almac BA 1008
During the Journées Horlogères open days, two versions of the Almac BA1008 will be on show: one with a bar feeder and one equipped with a special profile clamping system and a kit for machining precious metals. This small milling centre will also feature the Ecopack, a set of functions designed to save energy.

The Journées Horlogères open days – an annual event not to be missed
As in previous years, the watchmaking industry is invited to discover new products and expertise specific to Moutier. Mr. Renggli concludes: “Our specialists will be delighted to share their passion with visitors and to help them find solutions to facilitate their production of parts worthy of the Swiss Made label – that’s our commitment.”

World premiere for watch plate manufacturing from Röhm

27 10 2014

The watch industry is profiting to an increasing extent from the trend towards status symbols. Through increasing demand, the necessity for manufacturing faster is also increasing without having to compromise on the quality.

Swivelling: Then, the chuck is swivelled by 180° on the machine (e.g. by a divider). In the process, the tool support swivels as well.

After the machining of the first side, the chuck is swivelled by 180° on the machine (e.g. by a divider). In the process, the tool support swivels as well.

These requirements for more efficient and faster machining possibilities require clamping solutions that are perfectly matched to the watch industry. With the new plate chuck of the “micro technology” series, Röhm makes it possible for the first time to machine both sides of plates with one clamping operation. So far, plates have been machined using two clamping operations: first the top side and then – after reclamping – the bottom side. This reclamping operation takes not only valuable time, but it also introduces a loss of accuracy.

To machine on both sides in one clamping
The cumbersome way of machining plates caused a great deal of unrest amongst the employees of Switzerland’s Röhm Spanntechnik AG. They wanted to offer Swiss watchmakers an efficient alternative that did not cause the machining accuracy to deteriorate. Quite the opposite: The new chuck was to be even more accurate. Hence, an ingenious solution was found together with the German parent plant of the clamping technology specialist with the involvement of well-known watch manufacturers: a chuck that for the first time makes it possible to machine plates on both sides with one clamping operation.

To simply change side
The patented innovation clamps the plate on a console and the first side is machined. Then, the chuck is swivelled by 180° on the machine (e.g. by a divider). During the automatic swivelling operation, the workpiece support also swings to the other side of the plate. This ensures a secure support for the plate on both sides, and overpressure is prevented. Now, the second side of the plate can be machined reliably and without any loss of accuracy.

Encapsuled stainless steel screws diam. 0.99 mm x 0.34 mm

24 09 2014

Micronora started yesterday and visitors can discover many microtechnology innovations. This morning, we put the light on a small French SME that presents amazing achievements in terms of micro-machining and micro-moulding.

At Micronora, companies active in "small and precise" are emphasizing their skills in those fields that become more and more important for micro-mechatronics and microtechnology.

At Micronora, companies active in “small and precise” are emphasizing their skills in those fields that become more and more important for micro-mechatronics and microtechnology. Example, the new encapsulated micro screw designed vy Vuillermoz Philippe SAS and decicated to high-end watchmaking.

Vuillermoz Philippe SAS has developed an encapsulated micro screw for one of its Swiss customers. It is an essential element for an innovative system of high-end mechanical watch movement. A patent has been filed and is pending.

Micromachining? It is certain.
The challenge faced was huge in terms of research and development, micro-machining and micro-injection where the tolerance on the diameter of the moulded part is 0.99 mm + 2 /-3 µ. The specialists of the company have done it and the parts are perfectly meeting the requirements. The company spokesman says: “Our customer was delighted as the result surpasses his expectations”. Despite of being a small company, every aim was respected (quality, technique, delivery time).

Amazing facts
Knowing that a gross grain of material weight 0,02 gram, it allows the production of 14 molded parts. The weights are very light: the total weight of the encapsuled part is 0.0051 gram, the weight of the single insert is of 0.0037 gram, the weight of the material on the part is of 0.0014 gram.

These skills and parts can be discover until Friday (as well as many other things of course) in Besançon.

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.
