15.3 million automobiles will be sold in the USA in 2013 alone. Even higher sales figures are anticipated for 2014. Manufacturers primarily want to meet the increased demand, including for automobiles with alternative drive systems such as hybrid drives and electric motors, by increasing their productivity. With its successful machine-tool concepts, EMAG has frequently demonstrated that productivity can be boosted above all by using state-of-the-art machine tools and the company wants to continue to do this on the market in the USA, a market that has been important traditionally. The EMAG branch in Farmington Hills in Michigan that has been successful for many years now offers an absolute guarantee of EMAG reliability and presence in America. This EMAG plant supplies a wide variety of customers throughout North America and thus makes a small but important contribution to boosting productivity in the USA. Let us convince you of the quality of our machines and the possibility of boosting production at WESTEC which is to be held in Los Angeles between October 15 and 17. You will find EMAG in the Convention Center at Stand 2820.
VT 2-4 vertical turning machine – shaft production for maximum productivity
Shafts are central components in an automobile’s powertrain. Thus, boosting productivity for this manufacturing process also has a clear effect on overall productivity. The vertical, 4-axis pick-up-turning machine VT 2-4 allows machining of shafts with a length of up to 400 mm and a diameter of up to 100 mm. Our consistent demand for maximum productivity is demonstrated by integration of the automation solution whereby the machine loads itself with raw parts using workpiece grippers. It takes approximately 6 seconds to change the workpieces and this thus leads to short idle times and, consequently, lower component costs. The actual turning process for which two tool turrets, each with twelve tool positions, are available (fitted with turning tools or driven tools) is performed at a speed of 6,000 rpm in extremely short cycles. The integrated automation system, combined with the compact vertical machine structure, allows you to configure production lines with a very small footprint. The VT 2-4 vertical turning machine is consequently ideally suited to integrating shaft production in existing manufacturing systems.
VL 2 – pick-up turning machine for small chuck parts
Besides the shafts, it is mainly chuck shafts which are involved in the production of automobiles. The fact that small chuck components need to be machined to an increasing extent in order to implement more compact and, thus, more lightweight parts is primarily due to the further developments in the field of boosting energy efficiency.
The VL 2 is designed to machine chuck parts with a maximum diameter of up to 100 mm and a length up to 150 mm. At the same time, the VL 2 offers a whole range of clever design details and hi-tech components which allow high productivity. These include the pick-up spindle which loads itself with raw parts from the integrated conveyor and the tool turret equipped with 12 tool positions which allows diverse machining scenarios. To date, there has not been such a compact manufacturing solution for machining hard or soft chuck parts. The machine concept is supplemented by a machine base made of MINERALIT® polymer concrete that ensures high strength and excellent vibration damping.

TD Convention Center, Booth 701
Forecasted growth rates of 6.3% in sales of automobiles in the USA clearly demonstrate one thing: that the USA is and will remain one of the most important trading partners for Germany and German industry. The USA is traditionally an important market for EMAG, a leading machine tool builder in Germany. This is emphasized by the fact that EMAG has been present in Farmington Hills, Michigan, for many years now. Thanks to the deep roots that EMAG has in the USA, it is not only an important employer in the region near the “Motor City” of Detroit, but it is also a reliable business partner for numerous companies throughout North America. See the quality and reliability of our products for yourself at this year’s South-Tec show in Greenville, South Carolina. EMAG will showcase its machines in the TD Convention Center at Stand 701 at the trade fair to be held between October 29 and 31, 2013.
VL 2-P – productivity thanks to pendulum technology
When the aim is to shorten idle times, there are very few machines which can rival the EMAG VL 2-P. Workpieces up to 100 mm in diameter can be machined on the VL 2-P with unbeatably short cycle times. While there is a pause on other machines to allow the workpiece to be changed, the next workpiece is directly ready to machine on the VL 2-P. The key is that 2 spindles are used and these load themselves alternately while the tool turret swings between the machining positions. When machining is completed on one spindle, the tool slide moves to the second spindle to start a new machining process. Loading and unloading of the spindles which now occur in parallel with machining are virtually eliminated from the machining process and reduce idle times to an absolute minimum.
VT 2-4 – top-quality shaft machining
The vertical, 4-axis pick-up-turning machine VT 2-4 allows machining of shafts with a length of up to 400 mm and a diameter of up to 100 mm. Our consistent demand for maximum productivity is demonstrated by integration of the automation solution whereby the machine loads itself with raw parts using workpiece grippers. It takes approximately 6 seconds to change the workpieces and this thus leads to short idle times and, consequently, lower component costs. The actual turning process for which two tool turrets, each with eleven tool positions, are available (fitted with turning tools or driven tools) is performed at a speed of 6,000 rpm in extremely short cycles.
VL 2 – pick-up turning machine for small chuck parts
The VL 2 vertical pick-up turning machine is just the right choice for machining chuck parts with a maximum diameter of up to 100 mm and a length of up to 150 mm. At the same time, the VL 2 offers a whole range of clever design details and hi-tech components. These include the pick-up spindle which loads itself with raw parts from the integrated conveyor belt and the tool turret equipped with 12 tool positions which allows diverse machining scenarios. The machine body made of MINERALIT® polymer concrete ensures high strength and excellent vibration damping which is indispensable particularly when machining small chuck components.
VL 5i – flexible and efficient
Be it small or large series production, the EMAG VL 5i is the ideal manufacturing solution for turned parts up to 250 mm. The VL 5i is an interesting manufacturing solution above all for small- and medium-sized component producers, thanks to its excellent characteristics (e.g. short retooling times and fast programming). An automation system functioning on the basis of the drag-frame principle is integrated to round off the equipment features. This automation system, combined with the pick-up technology from EMAG, is the basis for the high productivity of the VL 5i. The workpieces are conveyed to the inside of the machine via the revolving automation system. The pick-up spindle loads itself there and it also deposits the finished workpiece back on the conveyor after machining. The advantages are obvious: the revolving automation system allows simple and very reliable loading and unloading of the parts, while the self-loading spindle ensures maximum machining reliability since clamping errors are virtually completely eliminated.

The International Monetary Fund (IMF) estimates that the world economy will grow by 3.5 percent this year, with the impetus coming less from Europe and more from dynamic, newly industrialized countries. One example is the automotive industry. According to the association for the German automotive industry (VDA), China’s share of the market in passenger cars increased by 59% and that of Brazil by 18% during the first few months of 2013. The same market is also growing in India and Russia. For a long time, new production facilities have been planned and are under construction, providing great opportunities for the machine tool industry – as the example of EMAG proves. Specialists are developing turnkey manufacturing systems that are tailor-made to suit specific market conditions, with the new production facilities in particular gaining substantially from this increased market activity.
Whether in the automotive or energy supply industry, the development of industrial key sectors within the BRIC countries (Brazil, Russia, India, China) has a direct influence on the machine tool industry, as it is this branch that, in the end, must supply most of the necessary manufacturing solutions. There are numerous indicators for this fact. For instance, according to Germany Trade and Invest (GTAI), the Russian enclave of Kaliningrad will – over the next 3 years – will see an investment of 3 billion Euro in six assembly facilities and fifteen sub-supply companies for the national automotive industry, with more international sub-suppliers also establishing outlets in the market. Similar activities are reported from Brazil. According to Anfavea, the country’s automobile association, approximately 22 billion USD are to be invested in production between now and 2015. In India, economic growth is generally attracting “an abundance of investment projects in the country’s infrastructure, as well as in new industrial complexes,” states GTAI.
The German machine tool industry is prepared for such a dynamic development and the opportunities it provides can be seen in the textbook case of EMAG. Their specialists see themselves as “partners in solutions” for the metalworking industry. Such an approach is of great importance, especially in the emerging markets. “As it happens, we don’t just deliver a machine tool. We deliver closely pinpointed manufacturing solutions that are, in every respect, tailor-made to customer requirements”, explains Dieter Kollmar, Managing Director of EMAG Holding GmbH. “This applies, of course, to typical factors such as batch sizes, component variants or, more generally, the flexibility of the processes applied. At the same time, we determine locally the technologies, automation equipment, interfaces and control systems required.“ The advantages for the customer are obvious, especially where an existing production line is extended or where a greenfield manufacturing facility must be created in a new market place. Our manufacturing systems are always “from a single source.” Even complex processes with peripheral machines and equipment are presented as turnkey projects by EMAG, thus considerably reducing the efforts of local production planners.
VL 2: Highly effective, truly outstanding space saver
The VL 2 is a pick-up turning machine with which the EMAG engineers are fulfilling a combination of two extreme demands: highest possible output rates on the smallest possible footprint. “This is a truly all-important aspect,” confirms Dieter Kollmar. “Although the floor space requirement for this vertical turning machine is just about 5 square meters, it is a machine of substantial capability, including a fully comprehensive automation concept with conveyor belt, workpiece storage and pick-up spindle. In combination with vertical turning, this results in very fast machining processes. “In other words, short loading travel guarantees the lowest possible component cost. Compared to horizontal turning machines, productivity rates increase quite noticeably. And maintaining the VL 2 is simple. All service units are freely and quickly accessible. The user can set up the machine in one step. “That too is important, when productivity levels enter the equation. Operators without prior experience, working at a new and unfamiliar location, will be able to quickly familiarize themselves with the machine. All in all, this is an optimal solution for those who want to extend production with as little investment as possible,” notes Kollmar.
VT 2-4: For demanding shaft production
A similar approach is shown with the VT 2-4 Vertical Turning Machine, with which the EMAG specialists have created an equally fast manufacturing system for shaft production. Even demanding machining processes can be realized on it. When machining shafts up to 400 mm length and 63 mm diameter, component costs reduce considerably, with extremely short chip-to-chip times (as with the VL 2) being the reason. Workpiece grippers transport the workpieces into the machine and remove them again, once they have been machined. Depending on the workpiece, the changeover can be accomplished in just 6 seconds. And the actual turning process is fast, too. 4-axis machining allows the component to be machined from two sides simultaneously. Vertical alignment of the workpieces provides consistent process integrity, as the unrestricted chip flow prevents the formation of clusters in the machining area.
Central project management
“We are convinced that these EMAG solutions are optimally designed to cover not only the specific requirements of an emerging market, but also those of Europe and the USA,” as Dieter Kollmar his company’s philosophy. Everything is greatly simplified, starting with production planning, as there is no need for separate workpiece and finished component storage, with the added advantage of a reduced floor space requirement. At the same time, the EMAG Group engineers act as central project developers, having access to machines with optimal interfaces. This guarantees a fast run-in and makes the machines maintenance-friendly. “When it is a question of arriving quickly at a wholly integrated, highly effective manufacturing solution, this approach must – from our point of view – be the first choice,“ Kollmar concludes.
