Award-winning – the VL 2 from EMAG is one of the most energy efficient machines in the world.
According to the “Future Panel” of the IW – the Institut der deutschen Wirtschaft (Institute for German Economic Research) – energy efficiency is becoming increasingly more important in the metalworking industry. The IW suggests that over 60 percent of the companies interviewed for the award are hoping for “a push forward toward innovation”. EMAG is an initiator of such innovations. Its experts develop machine tools and production processes that consume significantly less energy then its competition. In honor of this, EMAG has received the “Energy Efficiency Award” from the ZF Group. This award states that EMAG’s contribution has been honored as one of the top five.
From their efficient manufacturing technology to economical design and construction, the machine builders at EMAG have shown their in-depth know-how and experience in one of the most important fields of industrial development, to compete for the “Energy Efficiency Award” from ZF. The result convinced decision makers at ZF and EMAG’s competition entry called “Energy-efficient Production Machines” has been honored as one of the “Top 5 Projects“. In fact, in this particular sector EMAG was the only machine builder honored. Before the competition as part of its “Year of Energy”, ZF contacted approximately 600 of its suppliers, inviting them to participate in the competition. From 30 eligible entries, the specialists in driveline and chassis technology picked the top five. These five companies were invited to present their particular approach to efficiency on September 13th at ZF, Saarbrücken.
EMAG has been focusing on energy efficiency for years
“We are very pleased to have received this award”, declared Dr. Guido Hegener, Managing Director of EMAG Salach, Maschinenfabrik GmbH. “It is an incentive for us to continue on the chosen path. Our focus has been on energy efficiency for years.” During his presentation Dr. Hegener highlighted the various developments at EMAG:
“We have established how much energy each component consumes and where the biggest potential for savings lies”, explained Wolfgang Rummel, Head of Control Technology Development and Design at EMAG Salach Maschinenfabrik GmbH. He also referenced the concrete measures taken: EMAG includes the most efficient components in their standard machine design – for instance hydraulic packs with greater efficiency, low-wattage valves and intelligent auto-standby circuitry.
At the end of his competition presentation Dr. Hegener introduced a new overall objective: the development of the “sustainable factory”. He suggested that in future the production – together with the building in which it is situated and its technological contents – will be evaluated as a single entity. In conclusion, he expresses his belief that the measures taken to reclaim and recycle energy can lead to a potential saving of up to another 40 percent.

The ELC 250 DUO – a compact laser welding cell for the machining of differential housings. The DUO variant features two spindles. The twin-station operation allows for cycle time-concurrent loading and unloading of the work spindles.
“From Dual-Clutch Transmission to the classic differential: modern transmission technology is a pivotal research sector in the automotive industry. With new materials and altered geometries, designers optimize the functionality of the different gearwheels. Furthermore, these wheels are required in ever larger quantities, owing to the fact that the number of speed-gears in many passenger cars is on the increase. The innovations that promote the effectiveness of the production processes being applied include, for example, laser welding. With their ELC series of machines, the specialists at EMAG have developed integrated solutions for the application of processes with high output rates. The company’s in-depth knowledge of the production processes used for many transmission components has added to its competency in machine development.
(See the video HERE)
Herr Dr Andreas Mootz is Managing Director of EMAG Automation GmbH, Heubach, and responsible for the development of the production laser welding technology.
A first glance at a typical transmission component makes it plain where the challenges lie: even a small wheel with integrated synchronous gearing represents a relatively complex design. To manufacture it efficiently and at the highest precision calls for the two different parts to be produced separately and subsequently joined in a joining+welding process. It is at this point in modern transmission manufacture that laser welding comes into its own”, explains Dr. Andreas Mootz, Managing Director of EMAG Automation. “The process allows you to concentrate a carefully dosed amount of the energy emitted by the laser beam on the welding point, minimizing possible warping, while still achieving high welding speeds.” Furthermore, the welding process from EMAG uses solid-state lasers of outstanding energy efficiency. Whereas a classic carbon dioxide laser will achieve an efficiency factor of just about eight percent, the EMAG specialists can rely on an efficiency factor of approximately 20 percent with their technology. In other words, the power used to achieve the same optical performance is noticeably less, with energy costs in the production department massively reduced.
Machining area of the ELC 160 Laser Welding Machine for the welding of gearwheels. On up to three stations, the wheel assembly is pre-heated, joined and laser welded.
Stationary welding device scores heavily
Similarly effective within the total process is the integration of different production sequences on the ELC system. For starters, the work spindle uses the pick-up principle to load itself. The components involved are then clamped and pressed together in the joining press. The clamping technology used ensures the highly accurate positioning of the components, providing ideal conditions for the welding process. The design of the stationary optic ensures great operating safety and optimal stability of both machine and welding process. Depending on the workpiece material, the components can be induction-preheated prior to the welding process and brushed after it – and whatever is required, the process is completed in a single setup. The complete joining+welding process for a gearwheel takes just 12 seconds. This ensures that the components for a differential are thus finish-welded within no more than 40 seconds.
Laser welding the differential housing and the crown gear has meant a weight reduction of 1.2 kg or 2.65 lbs for this assembly.
Laser welding leads to advances in lightweight construction
The differential housing, as an example, clearly shows the possibilities the laser welding technology opens up in the general development of vehicle production. For some time now, automotive companies have been replacing the screw-type connection between differential housing and crown gear with a welded seam. The result: the cost of materials reduces and the weight of the assembly falls by approximately 1.2 kg or about 2.65 lbs. “When looking at the advances made in lightweight construction in the automotive industry, this kind of savings means the world”, explains Dr Mootz.

The customer benefits from practical knowledge
Seen in context, the welding specialists from EMAG Automation in Heubach, Germany are able to look back on a truly impressive history of success. Over 50 ELC systems have been sold in the last decade. All leading automobile manufacturers are using them. EMAG is a world leader in solid-state laser systems for the production of transmission and powertrain components. How did this success come about? “It is of decisive importance that we have at our disposal a large reservoir of know-how in the manufacture of these components. We understand the entire manufacturing process, from turning and grinding, and from welding right up to the concluding ultrasound testing process”, emphasizes Dr Mootz. “We can develop and construct the whole of the process chain. This significantly simplifies the planning of new production sites and the expansion of existing ones.“

General market development is positive
The general market development does play into the hands of the German machine builder: It is not only the successful dual-clutch transmission that ensures the need for more gears. Conventional transmission systems also tend to have more speed gears, as this reduces gas consumption and improves the driving comfort. “Having said that, we are offering a well proven welding technology that provides an energy-saving, high-precision manufacturing process and, at the same time, helps to advance lightweight construction and reduce production costs. This is no doubt a very successful and persuasive combination”, concludes Dr Mootz.

Continue readingIncreasing demands made on precision and the push for the decrease of price of modern components is pushing traditional manufacturing processes. EMAG offers three production technologies that complement or replace traditional processes such as turning, milling and grinding.
PECM for nickel- and titanium-based alloys
The ECM process is used to deburr components only at the points where material needs to be removed, and without it having any mechanical or thermal impact on the workpiece.
With its PECM technology (Precision Electro-Chemical Machining) EMAG presents a production process that opens up completely new fields of application. PECM is a process for the machining of high-alloyed materials, such as nickel- and titanium-based alloys. The disadvantages of traditional metal cutting – tool wear, mechanical stresses, micro-fissuring caused by heat, oxidization layering and the need for subsequent deburring operations – are eliminated, because this process is a non-contact one without heat input. All electro-chemical machining processes are characterized by stress-free material removal, smooth transition points and surfaces without ridge formations.
The ECM process is used to deburr components only at the points where material needs to be removed, and without it having any mechanical or thermal impact on the workpiece.
The advantages that the PECM process provides for different branches of industry are best shown with the example of a turbocharger for the automotive industry. The electro-chemical process is one that can be used to effectively in the machining of many high-alloy components, especially those in the high-temperature sector of the turbocharger – it also offers a much shorter and very efficient process chain. The typical clean-up operations necessary when traditional machining processes are used – such as deburring after milling – are no longer necessary. PECM machining operations are burr-free. And there is hardly any tool wear. The result: downtimes are minimal, when compared to milling (which requires regular tool changes). The process as a whole is sturdier and less prone to errors. And another important factor that our example of the turbocharger shows: the superb surface finish of the PECM process, where Rz-values of 0.3 micron can be achieved.
Will camshafts ever again be made of a single piece?
Another highlight is EMAG’s heat-shrink assembly technology, a process that scores particularly well in camshaft production. The high degree of precision achieved with the joining process drastically reduces the number of cam profile grinding operations or – with the use of precision cams – avoids them altogether. Another benefit of the process is the ability to combine different materials in the construction of the shaft, such as forged cams (e.g. in 100Cr6) and sintered cams, which do not require regrinding. Accessory components, such as plugs and end pieces, can – like the shaft itself – also be made of better materials. This allows for the camshaft to be adapted to the requirements of the engine and to be optimized in load bearing capacity and manufacturing costs.
Operating costs reduced by 50 %
Production laser welding is already a highly productive process in the manufacturing of gearwheels. The use of diode-pumped solid-state lasers – such as disc or fiber lasers –reduces operating costs by up to 50%. EMAG has been involved with the use of solid-state lasers in the welding of powertrain components from an early stage and is considered a pioneer in the technology. EMAG again has fulfilled a promise to their users offering them the lowest possible cost-per-piece, by coming up with an innovative technology that brings true cost benefits.
For many applications, solid-state lasers allow welding without shielding gas. This not only reduces operating costs, it also avoids having to follow the annoying logistics imposed by the use of shielding and laser operating gasses. In many cases, the welding process can also be sped up considerably. This increases productivity and – through a reduction in energy input per unit length – reduces welding distortion, resulting in better component quality.
