CECIMO commits to contribute to a new european industrial strategy

Mr Luigi Galdabini, President of CECIMO and Managing Director of Galdabini SPA, was one of the renowned panellist at the first European Industry Day that took place on 28 February 2017. He supported SMEs’ view and reported the challenges that the industry faces accessing new technologies. This intervention was in line with the “Joint Declaration for an ambitious EU industrial strategy” signed by 125 European manufacturing associations, which calls the European Institutions to define and implement an ambitious European industrial strategy.

CECIMO voices the needs of manufacturing SMEs in the First European Industry Day
CECIMO welcomes the first European Industry Day that was organized by the European Commission and saw the participation of high-level policy makers, including Commission Vice-President Jyrki Katainen, and Commissioners Elżbieta Bieńkowska and Carlos Moedas. The event brought together hundreds of stakeholders from across Europe to discuss issues of high importance for the European industrialists.

The European machine tool industry was represented by Mr Luigi Galdabini, President of CECIMO and Managing Director of Galdabini SPA in the European Industry Day. As debater in the high-level panel on SME access to technologies, Mr Galdabini highlighted that cross-border collaboration between machine tool builders and technology centres is essential, but severe bottlenecks, hampering the competitiveness of industry, exist. “If European machine tool builders want to keep up with market trends, they need to be increasingly agile, develop new solutions that match the changing needs of machine tool users, and focus on incremental innovation, offering continuously improved goods and services to customers. Consequently, technology centres spread across Europe can join forces with manufacturing SMEs and help them in responding to these evolving demands. At strategic level, MT builders need more policy instruments that foster the link between research and business, and they also call for incentives, which underpin cross-border collaboration in Europe and support the internationalisation of manufacturing SMEs” added Mr Galdabini.

Joint Declaration for an ambitious EU industrial strategy
CECIMO and other 124 European manufacturing associations launched a week ago a Joint-Declaration that calls the European Commission, the European Parliament and the Competitiveness Council to define and implement an ambitious and coordinated European industrial strategy. “CECIMO finds very positive that the European Commission organises the first European Industry Day. Nevertheless, to safeguard the world leadership of European manufacturers and jobs in Europe, the Commission needs to follow up what stakeholders have been voicing and to come up with a comprehensive action plan focusing on the strengths of our businesses” stated Mr Filip Geerts, CECIMO Director General.

The Joint-Declaration for an ambitious EU industrial strategy highlights that, while competitors from across the world puts industry at the very top of their political agendas, develop and implement well-thought strategies, the EU falls behind its industrial policy targets. “There has been no better time to reaffirm Europe’s commitment to manufacturing, innovation and jobs. European associations representing 125 manufacturing sectors are ready to offer their cooperation to the European Institutions” points out Mr Geerts.

Scarborough UTC Invests in 600 UK’s industrial Machine Tools for ‘Engineers of Tomorrow’

Scarborough UTC’s brand new training facility was proudly opened in September 2016 with the aim of educating the engineers of tomorrow. To ensure the facility gives students the best possible introduction to industry, they sourced machine tools, almost in their entirety, from 600 UK.


Scarborough UTC acquired Colchester Student centre lathes, a Harrison Alpha CNC combination lathe, Clausing turret milling machines, pedestal drills and bandsaws to fill the workshop, accompanied by a range of Pratt Burnerd International chucking solutions.

Commenting upon the reason for choosing 600 UK, the Principal at Scarborough University Technical College (UTC), Mr Tim Englefield said: “We wanted machines that represented the standard of machine tools that local companies are using. We wanted our learners to be able to walk out of the UTC with an education that will enable them to walk straight into a local company and feel completely at home with the technology being used.”

“When we look at the characteristics of a machine, it’s a combination of factors that are important. As a government funded organisation, whatever we choose has to have a high ‘value for money’ factor”.
The Colchester Students have an unrivalled reputation for being the ultimate benchmark training lathes, incorporating an ideal compact footprint for an education workshop, allowing for Scarborough UTC to fit the maximum number of machines into their available space.
The geared headstock Colchester Student lathes provides learners with the very best equipment to gain industrial level training, providing a comprehensive grounding in the basics of turning.  They are built to standards in excess of DIN8606 and BS4656 Part 1, which combined with outstanding safety features that exceed all international safety standards, make it the ideal education workshop lathe. Additionally, all Colchester centre lathes come fully equipped with a full range of accessories, suiting any industrial or training application.

The UTC also has the Harrison Alpha 1350XS lathe with CNC capability, so students can pre-program machines in the computer suites at the college. The Harrison Alpha CNC combination lathe has a huge range of built-in educational training options, making it the favourite choice for colleges and training centres around the world.  The wide range of Alpha control options available enable learners to seamlessly progress from manual, through to full CNC turning, aided by working with conversational programming, 3D graphic displays and standard ISO programming capabilities.

High value-added Clausing mills, drills and bandsaws completes the 600 UK equipment supplied to this highly impressive learning environment, making the workshop a complete ‘all-encompassing’ learning package for the students.

The Clausing 2VS turret mills complement the Colchester and Harrison lathes perfectly and are rapidly becoming a key engineered product in the industrial milling sector and are ideal for transitioning students making the step from learning into industry.  However, as with every Clausing product, the 2VS mill is one of many in a wide range of turret and bed mills offered by Clausing.

Scarborough UTC chose the Clausing KC1016VS bandsaw and EKL25 pillar drills as compact, versatile, industry ready machine tools that learners could pick up and use very quickly when working on engineering projects. Clausing also supply a wide range of Clausing drills, bandsaws and grinders to suit any workshop environment whether in industry or education.

All Clausing machine tools go through the same rigorous quality controls as every other 600 Group product and the mills, drills and bandsaws are no exception.

The UTC model has been in operation for little over 5 years in the UK and the Scarborough facility is one of 48 such establishments in the UK. Scarborough UTC accepts students from the age of 14 and the students undertake the standard curriculum of maths, science and English as well as three engineering qualifications. These include engineering manufacturing, engineering design and electronics and control systems.

Mike Berry, 600 UK managing director said “We pride ourselves in supporting all our customers whether in education or industry and respond to their individual needs. All our machines are manufactured to be equally at home in any workshop environment and we firmly believe that using high quality industrial standard machinery is paramount for education establishments to get the best out of tomorrow’s engineers.”

Optimize thermal management during plastic injection with GF Machining Solutions’ AM S 290 Tooling Additive Manufacturing (AM) solution

One year ago, GF Machining Solutions signed a strategic partnership with global Additive Manufacturing (AM) leader EOS, headquartered in Krailling, Germany. The partnership demonstrates the companies’ commitment to advancing AM as a leading technology and working together to ensure its seamless integration into the conven-tional manufacturing chain.

GFMS AM S 290 Tooling2

The AM S 290 Tooling, based on the established and proven EOS technology, is a system dedicated to the mold and die industry and from now on world-wide available. A System 3R MacroMagnum chuck is fully integrated into the building system. In combination with the Reference Point Calibration software, it permits the absolute location of parts relative to the X/Y plane of the building platform, which in particular supports manufacturing of hybrid workpieces. It further integrates building platform handling with other machining processes to separate workpieces or accurately refurbish building platforms for re-use.

The integrated chuck is intended to be used in combination with standard pallets (e.g., used for hybrid parts) or building platforms equipped with a standard reference element. This signi-ficantly improves the ability for upstream and downstream integration of the AM process in the whole production process.

The hybrid mold insert is the most economical solution for parts characterized by geometrically simple and complex sections. Depending on material and size, such hybrid parts can be created by directly generating the additively manufactured part on top of the conventionally manufactured base or by separately finishing and assembling both parts.

With this system, GF Machining Solutions focuses on mold inserts with conformal cooling/ heating channels. These inserts can be used for any kind of plastic products in all segments. Thanks to AM enabled conformal cooling, customers can reduce their cycle time, increase their productivity and improve the overall quality of, for example, a critical plastic part with thin walls.

Advantages of AM are now well understood and its industrialization is a major step toward the future. GF Machining Solutions is actively collaborating with EOS to speed up development of this solution which will be a major step in fulfilling Industry 4.0 requirements.

Both in mold and die and other applications in various segments, GF Machining Solutions is at the forefront of efficiently blending traditional and new manufacturing technologies, not by optimizing parts and process flow but also by improving data flow and systems connectivity.

Affolter launches groundbreaking Worm Screw Power Skiving technology

Affolter Technologies SA, the technology and world market leader in micro gear hobbing centers for the watchmaking and micromechanical industries, launches a groundbreaking innovation: Worm Screw Power Skiving (WSPS).

AF110 plus2

“This cutting-edge technology was developed by our engineering experts in an intensive R&D process. Worm Screw Power Skiving allows us to finish a high-precision worm in only 6 seconds. If done by worm hobbing, every piece will take 25 seconds”, explains Managing Director Vincent Affolter. In other words: WSPS makes producers 4 times more efficient. Mr. Affolter: “This will increase the productivity and efficiency of manufacturers in the automotive and aircraft industries considerably.”

 
Big demand
Many producers in these industries need to manufacture large quantities of high-precision worms. The WSPS technology focuses on small worms with a module of 0.3 to 1.5. “Such worms are used in car seats or trunks, for instance. We see a big demand in the automotive industry, but also in other sectors”, explains Mr. Affolter.

 
Extremely fast process
The idea behind the new technology: Unlike in worm hobbing, where the hob turns much faster than the workpiece, the Affolter experts inverted the process. “The workpiece turns extremely fast, with 2 new spindles up to 12’000rpm, while the cutter turns much slower. Only highest quality machines like the Affolter AF100 plus and AF110 plus can reach this speed and at the same time provide the necessary stiffness”, states the Managing Director.

 
AF110 plus: convincing results
Over the course of the recent months, the Affolter engineers redesigned the well-established Gear Line model AF110 to optimize the WSPS process. The result is the brand new Gear Hobbing Machine AF110 plus. The workpiece spindles were successfully remodeled to reach the high speeds needed. The Affolter Marketing and R&D team also focused on completely redesigning the machine. “We integrated a cutting fluid filtration system and a chip disposal solution. This allows us to cope with all the requirements imposed by the workpiece up to module 1.5 and the production of large volumes of chips”, says Mr. Affolter. Additionally, the Affolter engineers and the marketing team improved the ergonomics through a redefinition of the machine base and surrounding as well as the human-machine interface. The very flexible AF110 plus also convinces with a function that allows to operate at reduced speeds with the hood open (Full Safety setup machine mode). Extensive test runs proved very successful, as Vincent Affolter recounts: “We achieved outstanding results processing both steel and brass. The new AF110 plus and the WSPS technology will open completely new opportunities for our customers.”

 
In the spotlight
A prototype of the AF110 plus will be showcased at the trade shows AMB in Stuttgart from 13-17 September and Micronora in Besançon/France from 27-30 September. Furthermore, Affolter will present the WSPS technology at IMTS in Chicago from 12-17 September and 
JIMTOF in Tokyo from 17-22 November.
