Technologieführer: Hatebur verkürzt Umrüstzeit massiv

Innovationen vor den Vorhang: Hatebur, ein weltweit führender Anbieter von erstklassigen Umformmaschinen, präsentiert an der Fachmesse WIRE in Düsseldorf vom 16. bis 20. April 2018 die bahnbrechende Kaltpresse COLDmatic CM 725. Die Maschine mit sieben Umformstufen ist für hochpräzise und komplexe Teile mit einer Länge von 8 bis 125 Millimeter und einem maximalen Drahtdurchmesser von 22 Millimeter konzipiert. Dadurch ist die COLDmatic CM 725 ideal für Hersteller in der Automobilebranche geeignet.

Neben der COLDmatic CM 725 steht bei der Fachmesse WIRE auch die Carlo Salvi CS 001 im Fokus

«Unsere Ingenieure haben mehrere Innovationen umgesetzt, damit die Kunden noch effizienter produzieren können: Mit einer Produktionskapazität von bis zu 180 Teilen pro Minute ist die CM 725 um vieles schneller als frühere Maschinengenerationen», berichtet Reinhard Bührer, Leiter Marketing und Verkauf bei Hatebur.

Umrüsten per Knopfdruck
Darüber hinaus wurde auch die Umrüstzeit massiv verkürzt: So wurde beim Einzug des Drahtes ein Linear-Servomotor eingebaut, der den Draht mit Zangen hochpräzise nach vorne schiebt. «Die Volumenkonstanz der abgeschnittenen Teile bewegt sich dadurch unter 0,35%. Zusammen mit der von der COLDmatic gewohnt hohen Qualität der Scherfläche, ergeben sich Abschnitte, die es erlauben, dass bereits auf der ersten Umformstufe umgeformt werden kann», sagt Bührer. Das Herzstück der Anlage bildet der neu gestaltete und mit Servo angetriebene Quertransport, auf welchem die Zangen für den Weitertransport der Abschnitte angeordnet sind. Jede Zange verfügt zudem über einen eigenen Servo-Antrieb, welcher individuell geöffnet und geschlossen werden kann und programmierbar ist. «Vor allem diese Programmierbarkeit bringt in Sachen Umrüstzeit einen immensen Vorteil. Anstatt alle Parameter mechanisch neu einzustellen, werden in wenigen Sekunden die zuvor gespeicherten Einstellungen übernommen», erklärt Bührer.

Durch den Einsatz der Servo-Motoren benötigt die Maschine viel weniger mechanische Teile, wodurch die Gesamtkosten im Vergleich zu Vorgängerversionen um fast 20 Prozent gesenkt werden konnten. Das innovative Schnellwechselsystem erlaubt es zudem, alle sieben Matrizen und Stempel gleichzeitig herauszuheben und mit vorbereiteten Einheiten zu ersetzen. Auf diese Weise können in 10 bis 15 Minuten alle Werkzeuge gewechselt werden.

Carlo Salvi CS 001: 660 Teile pro Minute
Neben der COLDmatic CM 725 steht bei der Fachmesse WIRE auch die Carlo Salvi CS 001 im Fokus, die am Hatebur & Carlo Salvi Stand live produzieren wird. Die CS 001 ist für sehr dünne Drähte zwischen 0,6 und 3 Millimeter konzipiert. Mit einer Matrize und zwei Stempel werden pro Minute bis zu 660 Teile geformt – eine imposante Geschwindigkeit. Die CS 001 überzeugt durch minimierte Rüstzeit, leichte Umrüstbarkeit und Benutzerfreundlichkeit. Sie ist ideal für die Produktion von Schraubenrohlingen und massiven Teilen. Selbst kleine Stückzahlen bis herab zu 5.000 Teile sind aufgrund der minimierten Rüstzeit rentabel.

Dr Roland Feichtl becomes President of the European Association of the Machine Tool Industries

During its meeting held on 22 November 2017 in Brussels, the CECIMO General Assembly elected Dr Roland Feichtl as President of CECIMO for a period of two years.

Succeeding in this role Mr Luigi Galdabini, Managing Director at CESARE GALDABINI S.p.A., Dr Feichtl has been entrusted with the responsibility of leading the European Association that represents more than a third of the world machine tool (MT) production.

During his Presidency, Mr Galdabini strongly addressed the issue of the investment gap. According to Mr Galdabini, corporate investments in Europe do not compensate for the depreciation rates. The obsolescence of the machinery park risks dragging European industry into a downward spiral of low productivity- low value added- low profitability.

CECIMO President Dr Feichtl affirmed that, in line with the previous presidencies, he “will continue to promote the strategic importance of our industry towards European authorities and citizens. I will make sure that manufacturing and the re-industrialisation remain on top of the EU policy priorities”.

He underlined how in such a complex environment, businesses are faced with common grand challenges such as globalisation, climate change, resource efficiency, regulatory pressures, and the increasing weight of emerging economies. “A few decades ago, maybe it was possible for companies and countries or regions to solve all their problems on their own” he added. “This is not the case anymore. Machines, factories, companies and, yes, also countries are linked more than ever”. CECIMO should help its members to tackle their challenges together.

During his presidency, he will follow closely the initiatives of the European Commission in the field of the Digital Single Market, which aims at achieving considerable benefits for the digital economy. Under his mandate, CECIMO will “develop industry information and expertise in new emerging areas of importance, e.g. Digitisation, Digital Platforms, industrial security and trust, as well as monitor new customer technologies, that change the workpieces to be machined like new drivetrain. CECIMO will look for the support of European authorities to sustain the efforts of its member companies in providing machine tool solutions that improve the energy-efficiency of combustion engines. Through this and similar actions, our industry contributes straightforwardly to the challenge of CO2 reduction for our society. “But we should compare the complete sytem of different solutions e.g. from production over use, till disposal of a car to help environment.” In a market driven economy, Authorities should only set targets, but not select a special technology as the right one to solve complicated technical issues.

Dr Feichtl will “use the success of the Italian campaign for tax and other incentives to promote the modernization of the machine tool infrastructure in the other CECIMO countries” and will push forward the discussion on circular economy within our Association and with industry stakeholders in order to achieve our sustainability objectives.

Beside this as President of CECIMO, he will continue to “explain to European authorities and citizens the strategic role our industry plays in boosting jobs, growth and investment across Europe, as well as the necessity to improve the business environment, in order to ensure the development of Europe’s manufacturing base within its borders, maintain its competitiveness and ensure a level playing field for our industry”.

ELŻBIETA BIEŃKOWSKA OPENED THE DEBATE ON ARTIFICIAL INTELLIGENCE IN THE CECIMO MEETINGS

Brussels, 21 November 2017 –CECIMO had the pleasure to host Ms Elżbieta Bieńkowska, Commissioner for the Internal Market, Industry, Entrepreneurship and SMEs, during its meetings in Brussels. In her address to industrialists and stakeholders on the role of artificial intelligence and machine learning, she encouraged companies and firms to get involved in the European Industrial Strategy.

 

(from left to right: Dr Roland Feichtl, Ms Elżbieta Bieńkowska, Mr Luigi Galdabini, Mr Filip Geerts)

Ms Elżbieta Bieńkowska was the keynote speaker of the CECIMO meetings on artificial intelligence and machine learning on 21 November 2017, in front of a selected audience of industrialists, MEPs, EU officials and stakeholders. The event was timely organised ahead of the Commission proposal on artificial intelligence and the Commissioner emphasized the important role of the European Commission in recognizing the potential economic and societal benefits of such technology. “By putting a favourable and stable business environment in place”, she said, “Europe can compete globally on both the development and uptake of AI solutions”. It’s important that Europe is ready to act upon the new challenges as they will affect different areas of our lives, from work to privacy, from governance to public research. In this context, the European Commission needs to mitigate the risks and prepare citizens to a smooth transition. Ms Bieńkowska went on by saying that “we need to avoid unnecessary anxiety based on far-fetched AI take-over scenarios that could distort public perception of AI”.

 

Artificial intelligence has a primary role in the Digital Single Market Strategy and the European Industrial one, where it will be important to converge physical and digital technologies on the industrial value chain. Among the many actions illustrated during the speech, the machine tool industry is particularly touched by the current EC evaluation of the machinery directive. The Commissioner confirmed that one of the areas they are looking at is whether the directive is adapted to respond to the changes brought by new digital technologies.

 

CECIMO is pleased that, in her outline of the EU Industrial Strategy, Elżbieta Bieńkowska mentioned the relevance of the industry and companies, inviting businesses of all sizes to be fully involved, as the process will be launched next year during the second EU Industry Day on 22 and 23 February 2018. Filip Geerts, CECIMO Director General, pointed out that “CECIMO can greatly contribute to the ongoing and future work of the European Commission in the Industrial Strategy and we are ready to get involved in any actions and initiatives taken by the European Commission”.

Okuma launches two-spindle smart CNC lathe 2SP-2500H

Okuma adds the 2SP-2500H CNC lathe to its line of a smart machines. The innovative front-facing twin spindles provide significantly higher levels of productivity and far greater reliability in mass production, especially for automotive parts. The compact automation-ready machine provides excellent floor space utilisation and integrates two lathes into one unit with a standard loader for continuous front and back work.

The latest entry in Okuma’s 2SP-H Series of two-spindle CNC lathes is designed to provide consistent quality in mass production while increasing efficiency through process-intensive machining and automation. The lathe enables stable unattended production over long runs via a high-speed loader feeding blanks. Due to the machine’s unique design, the loader is able to enter the 2SP-2500H regardless of the turret’s position. Since turret retraction is not necessary, workpiece transport and changeover times are greatly reduced.

With 5,000min-1, the lathe’s turning spindle offers the fastest spindle speed of its class. The 2SP-2500H offers unrivalled floor space utilisation with the smallest-in-class machine width of 2,200 mm. Despite its compact dimensions, the machine features an impressive maximum turning diameter of 250 mm.

The 2SP-2500H is 20% faster than previous models. With a maximum spindle speed of 6,000min-1 and a doubled max motor output of 7.1 kW, the machine’s milling capabilities are on par with that of a small machining centre. Other applications include powerful face milling, drilling and tapping.

Okuma’s Intelligent Technology application Thermo-Friendly Concept minimises thermal deformation and enables supreme accuracy. A tool life calculator predicts the remaining time before an exchange is required and prevents cutting edge breakage, thus reducing costs.

Powerful solution for three- to five-axis precision machining

With the Picomax 75, Fehlmann announces a powerful solution for three- to five-axis machining. The machine construction, the Z-axis travel, the geometry and the control unit are designed for five-axis operation with the company’s dividing and swiveling units.

The robust Picomax 75 is designed to increase efficiency wherever the highest precision and highest machining performance are called for.

Up to five axes are fully integrated in the control system. This combination is said to ensure optimum access and precision in five-, four- and three-axis machining. The Picomax 75 can also be ordered as a pure three-axis milling machine, whereby fourth and fifth axes can be retrofitted if required at any time. As is pointed out, the machine is easily accessible from the front, also in combination with the optionally available automatic parts handling.

At EMO Hannover 2017 the exhibit will be equipped with a six-axis articulated-arm robot to enable the handling of blanks without pallets. Thanks to the automatic, flexible re-clamping of parts by the robot, an all-over machining of workpieces is possible without operator intervention. Workpieces can be produced with fully automated manufacturing and emerge completely finished from the machining process.

Tornos continues to perform well

The Tornos Group performed very well in the first half of 2017. After a somewhat sluggish start to the year, demand for all product lines picked up significantly in every region from March onwards.

The Tornos Group improved all the key business figures in the half-year financial statements markedly. Order intake for the first half of 2017 was up by a total of around 65% on the figure for the equivalent prior-year period (and even by 98% in the machines business), the backlog rose by around 75% compared with the end of 2016, and net sales were also considerably higher than in the same period of the previous year. Tornos is back in profit with EBIT of CHF 1.7 million and a net result of CHF 0.3 million. The Group expects the annual financial statements to show positive EBIT and a positive net result. In the first half of 2017, the Tornos Group posted total net sales of CHF 82.1 million (first half of 2016: CHF 69.8 million, +17.5%) and order intake of CHF 103.2 million (first half of 2016: CHF 62.6 million, +64.7%). In the machines business, Tornos even managed to increase order intake by 98%. The operating result (EBIT) for the first half of 2017 came to CHF 1.7 million (first half of 2016: CHF -2.4 million), and the net result was CHF 0.3 million (first half of 2016: CHF – 3.5 million).

In the first half of 2017 the Tornos Group generated positive free cash flow of CHF 10.1 million, thanks partly to a substantial reduction in net working capital since the start of the year. The Group had experienced a cash drain of CHF 9.1 million in the first half of 2016. The number of people employed by the Tornos Group (in full-time equivalents) rose slightly, from 631 at the end of 2016 to 641 at the end of June 2017.

 
Market position improves considerably
Streamlining and expanding the product range enabled the Tornos Group to strengthen its position considerably in the various market segments and regions in the first half of 2017. Order intake improved markedly in all regions. During the past year, the automotive industry – the most important market for Tornos – suffered from uncertainties and great reluctance to invest. Confidence returned to this market in the first few months of 2017 and demand for capital goods increased sharply, especially in the higher-price segment. The market segments of medical and dental technology and electronics also saw demand for high-value capital goods increase significantly in the first half of 2017. It is only in the watchmaking industry that no turnaround has yet been perceived.

 
Demand for high-end products rises strongly
Having already boosted sales of machines in the medium-price segment in the second half of 2016, the Tornos Group achieved very gratifying sales in the highend multispindle segment in the first half of 2017. This was largely attributable to the newly launched MultiSwiss models, which can be used for manufacturing parts with a diameter of up to 32 millimetres. In June 2017, Tornos delivered the 200th machine from the MultiSwiss range, which was launched in 2011. Tornos also intends to add extremely innovative high-end machines to its Swisstype automatic lathe (single-spindle) product range. These will be unveiled to an interested specialist audience at EMO Hannover, the industry’s leading trade show, in September 2017.

 
Systematic implementation of the flexibility strategy
As part of its flexibility strategy, the Tornos Group began outsourcing a substantial portion of component manufacture to third parties at the beginning of 2015 via targeted global supply chain management. These activities will be stepped up in the second half of 2017. At the same time, the Tornos Group will invest in ultra-modern manufacturing technologies in order to be able to produce its key components and small series more efficiently.

 
Outlook for the second half of the year
The overall economic prospects and the forecasts for the Swiss mechanical engineering industry are all positive for the second half of the year. Thanks to its streamlined product range which is ideally tailored to the needs of its customers, Tornos is well equipped to continue to benefit from the revival in demand in the core markets. The Group also expects positive EBIT and a positive net result for
the 2017 business year.
