The automotive industry is facing a major challenge: the Euro 7 standard stipulates strict limits for particulate matter emissions. Cars will then only be allowed to emit around three milligrams of particulate matter per kilometer – a drastic reduction compared to today’s values of up to 40 milligrams. To achieve these ambitious targets, car manufacturers are increasingly relying on innovative technologies such as coated brake discs.
Laser cladding is a promising process for manufacturing these ultra-modern brake discs. In this application, a special material powder made of stainless steel and hard carbide is welded onto the surface of the brake disc using a laser. The result is brake systems that not only drastically reduce particulate emissions, but also minimize wear and prevent corrosion.
However, the design and development of this new coating technology also creates new challenges in post-processing. With the VLC 450 DG grinding machine, EMAG offers a specialized solution for the machining of these high-tech brake discs.
We spoke with Jannik Röttger, Head of Grinding Technology at EMAG, about this innovative technology and EMAG’s response to the challenges of the Euro 7 standard.
The 47th annual SHOT Show proved once again why it is the premier event for the shooting, hunting and outdoor industries. With record-breaking exhibit space, more than 54,000 industry professionals in attendance, and groundbreaking innovations on display, this year’s event set a new benchmark for industry engagement and collaboration. For EMAG, the SHOT Show was the perfect opportunity to introduce our latest advancements in electrochemical machining (ECM) for rifle barrel manufacturing, particularly our cost-effective 2-spindle ECM rifling machine.
At its core, cylindrical grinding is all about precision. This process involves machining the external or internal surface of a cylindrical workpiece using grinding machines equipped with rotating wheels. These machines remove material through abrasion, delivering exact dimensions and smooth finishes. Whether it’s external or internal grinding – or even a mix of both – this technique plays a pivotal role in producing high-quality parts for industries like automotive, aerospace and more.
Imagine your old machine tool suddenly being able to do more than ever before – and with less energy consumption. What sounds like a dream has become reality with EMAG’s retrofit solutions. In this interview, Markus Heidel, Head of the Retrofit Business Unit at EMAG, explains how used machines can be turned into real speedsters and why this concept will shape the future of mechanical engineering.
With the introduction of the EURO 7 standard, braking systems in cars will have to undergo massive changes, as this is the first time that particulate emissions have been regulated and many current models do not meet these requirements with their brakes. What does this mean in concrete terms for automotive production, what role does the hard coating of brake discs play and why is EMAG’s new laser metal deposition technology the ideal solution? An interview with Dominic Grimminger, brake disc coating expert at EMAG.
ECM is an innovative technology for machining the barrels of sporting guns. A special rifling module is used in the PI machine. The result is a highly precise and homogeneous field rifling profile for short and long barrels.
Alexander Morhard, Technical Sales Support Manager at EMAG SU, talks in an interview about the G 160 gear generating grinding machine, the fastest machine of its kind for gear production. He provides insights into the innovative axis concept, the high gear quality and the wide range of possible applications in gear manufacturing and electromobility.
How can particularly large and heavy components be produced using lean production solutions? This question is becoming increasingly important, especially in the commercial vehicle sector, because price pressure in the market demands the lowest possible unit production costs. In this context, the VSC 500 and VSC 500 DUO machines from EMAG are real “game changers” for manufacturers. They load themselves and then ensure fast and precision complete-machining in a single setup or two. A conversation with Peter Gröner from the Turning Business Unit at EMAG about the enormous possibilities of this technology.
High precision, fast processes, small footprint – the VSC 500 and VSC 500 DUO vertical pick-up machines ensure efficiency in the machining of large components, such as those required in the commercial vehicle sector. They load themselves and then start complete-machining in a single setup or two setups (DUO).
In the world of machine tools, the optimal design of processes is crucial to achieving the highest precision and efficiency. In today’s blog article, we spoke to Jörg Lohmann, Head of Technology and Product Management and Member of the Management Board at EMAG KOEPFER, to find out more about how hobbing processes are designed, using planetary gears as an example. Jörg Lohmann brings almost 20 years of experience in the design and application of gear hobbing machines and gear cutting processes and gives us a deeper insight into the decision-making behind these processes.
