25 years of Starrag Sprint Z3

Machine tool builder Starrag is looking back on a special engineering anniversary: 25 years of Sprint Z3. The inconspicuous machining head of the EcoSpeed series was officially presented for the first time in 2000. What began as a solution for a military aircraft soon became a key module in modern aircraft production.

The Sprint Z3 parallel kinematic machining head has proven to be a real drawcard and, despite its compact design, is always a talking point.Even after 25 years, Starrag says the technology behind it still amazes. The drive head contains a highly dynamic, three-axis kinematic system which, unlike conventional fork heads, swivels via articulated kinematics to enable rapid yet precise tool movements.

UK METALS INDUSTRY BECOMES THE EU CIRCULATORY MOVEMENT’S FIRSTOFFICIAL FOCUS

With the EU’s Ecodesign for Sustainable Products Regulation (ESPR) having entered into
force last year – a movement setting the standards for product circularity and sustainability
in the EU marketplace – many in the metal sector have not yet felt a sense of urgency to
begin their compliance journeys. However, with the EU recently revealing its Energy
Labelling Working Plan 2025-30, the industry needs to now prioritise regulation-readiness
more than ever before. In this article, Matthew Ekholm, DPP and Circularity Specialist at
Protokol, provides the inside track.
In simple terms, this new plan, published by the EU, highlights how iron and steel are among
the first industrial materials for ESPR action. It goes on to highlight how the delegated act
(information concerning the detailed breakdown of regulatory requirements for the
industry) is also just around the corner – expected in 2026.
The EU’s focus on the metals industry and looming ESPR deadlines is perhaps unsurprising
when considering that the industry is responsible for 5% of CO₂ emissions in the EU and 7%
globally.
With the EU’s 2050 climate neutrality target remaining a key driver behind the
Commission’s Circular Economy Action Plan (CEAP) – the framework upholding the ESPR –
the EU aims to reduce pressure on natural resources, prevent the production of waste and
toxic materials and ensure sustainable materials remain the key source circulating in the
marketplace.
The ESPR adds another layer of complexity to this, as it defines the standards and criteria for
the environmental performance of products sold within the EU, and is soon to mandate
Digital Product Passports (DPPs) to ensure products circulating in the specified sectors meet
the required sustainable criteria. The ESPR sets out a range of requirements concerning the
handling and composition of products. These include product durability, reusability,
upgradeability and reparability, as well as data on carbon footprints and recycled content.
All requirements which will be verifiable via DPPs and are set to impact any business placing
ESPR-regulated products in the marketplace.
As a key part of the ESPR, DPPs are fast-becoming a central force in ensuring a circular
economy prevails, as they will remain applicable across product groups, including (but not
limited to) the steel sector.

For the metals industry, the delegated acts, which are soon to be announced, will provide
companies with the detailed requirements they need to ensure the DPP mandate is met and
their products satisfy the sustainability criteria coherently. As the EU Commission plays a
central role in influencing the circular future of the European steel industry, DPPs will
support firms in their compliance with the ESPR.
DPPs, through inherent design, act as a lynchpin for circularity efforts by facilitating
information sharing that is vital to all in the value chain in terms of the sustainability
credentials of a product. They act as a digital record of a physical product, securely keeping
track of information about it from across its lifecycle, including data about its sustainability
credentials, such as the carbon footprint of its production and more.
With their built-in transparency, DPPs allow iron and steel manufacturers to reduce red tape
and streamline their path to EU compliance.
The UK steel industry has held a longstanding relationship with the EU, particularly as a key
target for UK steel exports. Simply, if they do not meet the ESPR requirements,
manufacturers risk being cut off from the market. This issue is particularly important when
noting the already highly competitive nature of the industry, and the need for modern steel
manufacturers to remain ‘up to date’ and timely if they want to remain relevant in this
competitive global marketplace.
Similarly, Brexit has largely affected the metals industry, with the sector facing various
challenges with the country’s departure from the EU. As the loss of EU-funded research and
development programmes has affected innovation, competitiveness and increased
administrative burdens, compliance with the EU’s ESPR can help ‘soften the blow’ for steel
manufacturers by ensuring firms remain ‘competitive’ from a sustainability perspective.
By strategically embracing DPPs, metals manufacturers can streamline compliance across
multiple regulatory fronts. Not only does this help satisfy ESPR requirements, but it also
supports alignment with the EU’s broader push for product circularity and decarbonisation –
a clear win-win.
With both the EU and UK governments deciding in May 2025 to link the two regions’
Emissions Trading Schemes (ETS), steel businesses across the EU marketplace are now
exempt from the Carbon Border Adjustment Mechanism (CBAM) costs and administrative
burdens. Without this linkage or the improved market access in place, UK producers faced
the prospect of increased trade friction with the EU.
Aligning with the EU’s ESPR is not just a matter of regulatory compliance – it’s a chance to
strategically fuel this relationship. As the EU doubles down on sustainability and circularity,
steel producers that fail to meet these standards risk damaging access to a key market.

Compliance with ESPR offers the opportunity to future-proof operations, strengthen ties
with the EU, and commit to a greener future.
There are additional benefits to consider beyond aiming to remain competitive For example,
through the ESPR’s use of DPPs, administrative burdens can also be simplified for the sector
by streamlining compliance with other sustainability regulations, enhancing transparency
and facilitating data sharing across the value chain.
Ultimately, the EU is setting the standard when it comes to the 21st-century steel sector,
aiming to foster an eco-market via numerous regulatory shifts before it is too late. To
ensure relevance amid this vastly competitive market, companies that export to the EU
market must start considering compliance now with the EU movement or risk being shut out
totally.
DPPs can play a central role in helping the steel industry boost its sustainability credentials.
By offering detailed product insights, DPPs enable companies to navigate multiple layers of
regulation more efficiently and effectively.
As the European Commission pushes for a competitive, low-carbon steel and metals sector
through its new Steel and Metals Action Plan, aligning with the ESPR offers UK companies a
strategic path forward, one that supports compliance across several complex regulatory
frameworks simultaneously.

Precision machining cutting-edge research institute

The Max Planck Institute of Quantum Optics (MPQ) in Garching near Munich has its origins in a laser research project group founded in 1976. With four departments in different areas of laser development and quantum physics, the institute researches the interaction of light with quantum matter at extremely low temperatures. 

The laboratories use complex, high-precision equipment built with the support of an in-house workshop. Some 15 engineers manufacture precision components on DMG Mori machine tools. The machine shop includes three of the manufacturer’s five-axis machining centres, a DMU 50 and a DMU 65 monoBLOCK plus, most recently, a DMU 40.

Research at MPQ provides physicists with ever deeper insights into physics at atomic scale. The results are so groundbreaking that two Nobel Prizes in Physics have been awarded to Garching employees.

Michael Rogg, who has been at the institute since 1986 and been head of the workshop for the last 13 years, says: “Our laboratories need special optical instruments to carry out their experiments. The stability of the DMG Mori five-axis machines and their extensive cooling systems allow the required high-precision machining of the often complex geometries, sometimes down to tolerances of a few microns.”

An extensive variety of materials is used in the workshop. As many experiments are carried out in a vacuum, stainless steel components are common, but aluminium, copper alloys and special plastics are also widely used.


Says Rogg: “Unlike in industry, profitability is only a secondary concern in research. What counts first and foremost is a perfect result. One person is always responsible for the entire production of a component, from programming through to final quality control.”
