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!

40 years at the service of its customers

The recent change at the head of Suvema, the company located in Biberist (SO) doesn’t affect the strategy that has ensured the success of the company for 40 years: personalized high quality service established as corporate culture.

Mr. Robert Haüsler (left) and Mr. Roland Gutknecht before a Citizen machine “boosted” by Suvema.

To open the company to a new style of management while keeping what makes its strength: this is the challenge of a successful transmission as confirm MM. Robert Haüsler, former owner and Roland Gutknecht, new CEO of Suvema SA.

Pioneer of CNC machine tools
Founded in 1974 for the sales of machine tools, Suvema SA quickly acquires the general representation of Okuma. Growing regularly over the years, the company now represents six world-famous brands, allowing it to occupy an important place in the field of CNC machining in Switzerland. The variety of represented products can cover many sectors of activities: high precision turning (with Citizen sliding headstock lathes), medical (with Okuma CNC machines), the manufacture of tools and moulds (with Bridgeport machining centres) and much more.

To answer to the specific expectations of the customers
But the real strength of the company lies in the fact that no machine, or almost, leave the Biberist plant without having undergone a profound transformation. Adapted to the demands of customers, the machines customized by Suvema SA thus become, by input of various devices, complete machining solutions. Nowadays simple parts, just turned, for example, no longer have much future in Switzerland. We must therefore concentrate on complex parts with great value added. “Machines, capable of producing such parts become also become increasingly complex and we must be able at the same time to propose simplified setting up”, analyses Roland Gutknecht.

Far more than a reseller
The result after customization is often so different from the basic machine that Suvema SA considers itself not only as a reseller, but willingly assumes the role of Integrator and solution provider. Its numerous interventions on the machine give a consequent benefit to the Swiss customers. The machine sold in our country often offers a better performance than the same model sold in other markets. The service vision of Suvema seems to be good because the company sees its market share steadily grow. “The first sale to a customer is to the credit of the salesman. The following are the result of the quality of service”, argues Robert Haüsler.

TISIS 1.4, new developments for the end of the year

The first immediately noticeable change in this new version of the Tornos tool is in the name of the product: from now on, the software suite will be called “TISIS” which stands for “Tornos ISO Swiss Integrated Solution”.
tisis
But there is much more to discover, see the menu for the latest developments.

TISIS-Screen
The TISIS software suite features a new TISIS-Screen application for monitoring the machine inventory. This Windows application is an add-on supplied with the connectivity pack and also enables machine tool support catalogues or workpiece programs to be transferred or recovered.

Swiss GT26 & CT20
With the arrival of two new machines to the Tornos product range – the Swiss GT26 & CT20 – TISIS is the perfect addition for programming workpieces on these machines. Moreover, TISIS now offers program models in inches.

Workpiece time
One of the key new developments in TISIS version 1.4 is the calculation of the workpiece time. This value is actually calculated automatically when the workpiece is programmed. The following values are displayed: Workpiece time in seconds [s], Number of workpieces per minute [p/min] and Number of workpieces per hour [p/h].

Time diagram
In addition to automatically calculating the workpiece time, TISIS displays a time diagram based on the operations and the synchronisations between them. This is in the form of a Gantt chart, as this also enables the critical path to be displayed, giving a visual representation of the operations influencing workpiece time. The diagram is also refreshed automatically. It is also possible to display the time columns directly alongside the workpiece program.

TISIS WebStore
The design and features of the TISIS website have been updated: the new graphic design links to the official Tornos site. Its interface is now available in multiple languages (FR, DE, EN etc.) and customers have secure access to activate and manage their TISIS3 licences, or even subscribe to the newsletter (to stay up-to-date on the available upgrades and new developments, etc.).

If you have yet to purchase the TISIS software, it can be downloaded from the Tornos WebStore for a free 30-day trial here: http://store.tornos.com

Two spindles in a compact footprint

At the base of the specifications of the new s100 product line just unveiled by Bumotec, a simple idea: to create a product with maximum productivity in a minimal floor space. This while ensuring both quality of work and accuracy superior to the constraints of the watchmaking world. After 4 years of development, the s100mono and s100multi machines are being marketed and results exceed expectations. Meeting with Charles Dénervaud, responsible for marketing of the near-Fribourg based company.

Equipped with 2 electrospindles (max 60'000 rpm) and two systems to store tools, the s100mono maximises the use of hidden time.
Equipped with 2 electrospindles (max 60’000 rpm) and two systems to store tools, the s100mono maximises the use of hidden time.

Bumotec has developed a new concept of work with two spindles that is applied to several machines. The s100mono is a 3-linear-axis machining centre equipped with two working spindles. The s100multi machine has 4 workstations each with two spindles. In this case, the pallet holding the part moves from one position to another. The logic is the same as for a transfer machine. It is equipped with 144 tools, enabling significant gains on set-up times and unbeatable productivity. In this post, we will mainly talk about the s100mono version.

Lightning accelerations and maximised productivity
The machine is able to offer accelerations of more than 3 G (tested up to 5G). Our interlocutor says: “All the elements of the machine are known and proven. It offers a lot of possibilities and we discover new applications or methods enabling significant productivity gains every day”. And if nowadays the tools are not designed to work under those extreme conditions, it is evident that trends moves toward that direction and Bumotec is already prepared. To be able to control such a reactive machine, the company chose the Bosch Rexroth MTX Performance NC.

To benefit of hidden time to the maximum
In comparison with a classical single spindle machine, tests show very important cycle times improvements. When one requires 13 minutes with this technology, the s100 mono machine needs less than 8 minutes and an s100 multi only needs 2 minutes.

Comparison of cycle times between classical machining (one spindle) and the Bumotce S100mono and S100multi. In addition to high machine dynamics, it is mostly hidden time use which enables such gains. With two spindles, all tools changes or tools probing controls are conducted, while the second spindle is working.

In the case of realisation of larger series of parts or parts that require many operations, the s100multi combines four workstations identical to the s100mono version in a compact transfer centre.

Bumotec’s new premises for the future

The new building the company has started to build is large, clear, widely open and will have very low energy consumption. The work started with a brief ceremony with the presence of the authorities as well as the press on August 29, 2014.

M. Jean-Daniel Isoz in front of the new S100 Mono machine that opens a brand new category on the market. (You will be able to discover this new machine in our next issue and online indeed, stay tuned).

Located in Vuadens in the Fribourg Canton, the new building is ideally positioned close to the motorway and for employees; it’s only a few kilometers from the actual site that is definitely cramped and too small. With the planned growth of the company, this construction is highly anticipated.

High end building for high end machines
Once finished the new building will reach 14.279 m2. Jean-Daniel Isoz the directors says: “We won’t occupy the whole surface of the building and we will be able to rent about a third of it to companies interested in its assets like a +/- 1°C stable temperature all year long”.  Ideal for those who manufacture high precision machines and devices.

Good for the environnement and for the region too
The new building has been designed with the environment in mind and will use latest generation solar-panels and will comply with the latest eco-energy regulations. The CEO ads: “I’m quite confident we will hire many employees these following years” and indeed they fill find a nice place to work.

New compact industrial technology

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.
