EMAG Joins Senator Stabenow to Help Michigan New Jobs Training Program Initiative

Major machine tool company in Detroit supporting

Farmington Hills, MI – EMAG L.L.C. is a major machine tool supplier to the automotive, off-highway and energy sectors of North American industry and today proudly announced its full participation in the Michigan New Jobs Training Program initiative, led by Michigan Senator Debbie Stabenow, who detailed the program last week at Oakland Community College’s Advanced Technology Center on the Auburn Hills campus.  Senator Stabenow is introducing legislation in Congress, called the New Skills for New Jobs Act, which would involve federal matching funds to support Michigan and other states that have already begun helping community colleges with local businesses to create more job training and retraining opportunities.

EMAG already supports the MAT² program (Michigan Advanced Technician Training) here in conjunction with Oakland Community College and Henry Ford Community College, in which students engage in a study/work program with guaranteed employment at the end of defined period.  CEO Peter Loetzner comments, “We see the New Jobs Training Program as a logical extension of the student program, as many in the current work force need enhanced skills to perform the new tasks required by today’s technology.  This is especially true in our world of machine tools and related manufacturing.”

Speaking at Oakland Community College on September 3, Senator Stabenow said her new bill would provide a federal match equal to state training reimbursements, so that the repayment to the colleges would occur more quickly, plus there would be an increase in the number of eligible companies and workers participating.

Many Michigan businesses, especially those in the high-tech and automotive markets, constantly seek trained workers and have increasingly found it difficult to secure qualified people.  The New Jobs Training Program would enhance the skill level of the workforce, making the state a more attractive base of operations for more companies in both market segments.

Senator Stabenow further remarked, “This program is a partnership between businesses and the community colleges, reaching out to workers.  And it’s a way for the federal government to recognize that new job skills training – to match the jobs now available – is a top priority for moving the economy forward.”

The New Jobs Training Program in Michigan was begun in 2008 and last year trained nearly 10,000 workers in partnership with 44 companies, generating $76 million in additional wages for the Michigan labor force.

EMAG at WESTEC 2013

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.

Manufacturing Solutions from the EMAG Group – A Partner In Emerging Markets

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.

EMAG Tackles Non-Productive Time on Its Machining Centers

EMAG has a long history, starting back in 1867 in Bautzen, Germany, as an iron foundry and engineering works. Re-established 60 years ago in Eislingen, Germany, in 1952 to make lathes and special-purpose machines, today it makes manufacturing systems for precision metal components from its headquarters in Salach, Germany. Its machines range from basic round-part vertical turning centers to machining centers with as many as six axes handling large workpieces. They perform turning, milling, grinding, hobbing, drilling and more as singular purpose setup or combination machines.

The tools manufacture primarily automotive, off-highway, agricultural and oil field components. For example, EMAG tools are involved in transmission components for agricultural vehicles, such as gears, ouput shafts and idlers. “If you look at a dozer from the outside, you have a chain,” notes Peter Loetzner, CEO of EMAG’s U.S. subsidiary in Farmington Hills, Mich. “There are two large precision wheels that drive that chain. There are idlers on the bottom. Our machine can make all these round components.”

EMAG’s equipment differs from typical vertical lathe machining centers, whose head stock is mounted, typically horizontally, and a turret turns to do the machining. “Our turret is mounted in a concrete base, so it’s not moving,” Loetzner explains. “We have a head stock that moves outside of that design. That gives us better precision and better tool life.”

The machine builder takes pride in its ability to produce high-precision parts. In one example, Axle Alliance in Redford, Mich., needed to hold to a 25 µm tolerance for 390 mm diameter steel ring gears during hard turning, which is done prior to grinding the gear teeth. EMAG worked with Axle Alliance to develop a probing process that ultimately delivered a variation of less than 15 µm. Axle Alliance now uses six machines built at EMAG’s headquarters in Germany, each dedicated to a part line.

Another example comes from Precima Magnettechnik in Brückeburg, Germany, whose customers expect absolute perfection from, in this case, housings for brakes used mainly for wind turbines. Precima had had issues with machine vibration causing negative effects on tool life and surface finish. However, the rigidity of EMAG’s turning machines and the vibration damping quality of the base allows for the very high feed rates and cutting speeds required in precision hard-machining. Precima now runs four vertical pick-up turning machines from EMAG.

Loetzner gives much of the credit for the machines’ capabilities to long-time partner Siemens. EMAG has standardized on the Siemens Sinumerik 840D CNC platform, specifically the solution line and power line. Loetzner likes, in particular, that the CNC controller is an integral part of the PLC, and they are able to do almost everything through the CNC, including making it look like a PC for the operator. The common look and feel for the operators makes for easier onsite commissioning and cross-training, Loetzner adds.

In one recent case study, EMAG needed to provide grinding, turning and turn-grind machines to a major agricultural equipment builder, and the machine builder relied on the 840D CNC. “We needed to devise a control solution that would satisfy all the needs of the various machines we were supplying to this demanding customer, based on a common platform, to enable easier design, integration, startup, commissioning on-site and training for our customer’s operations and maintenance personnel,” Loetzner said at the time.

Similar control technologies are used on EMAG’s newer-technology machines, including laser welding and electrochemical machining centers. These technologies have little impact on the control or automation schemes, Loetzner notes, because they still are essentially performing the same task, whether in a dry, lubed, gas-cooled or underwater environment. Only the sensors and encoders need to change to accurately feed the relevant data to the control. In fact, the controls are often much simpler because the axes of motion are fewer, though more multi-axis and workpiece manipulating machines are being developed.

The CNC also enables remote monitoring over a wireless network so that process engineers can see what the operator sees on each machine. The agricultural equipment customer mentioned has used the remote monitoring capability on a wide variety of EMAG machines for several years, with all data communicated through a single information network that’s accessible by both EMAG and Siemens. Through this arrangement, they have been able to significantly reduce downtime, service calls and troubleshooting identification time.

More than 75% of the EMAG machines at this customer site are equipped with robotic devices. The lights-out capabilities this provide make remote monitoring that much more important. Remote monitoring can be done directly through the Sinumerik CNC in a one-on-one exchange with the customer, Loetzner notes, or even a three-way exchange involving Siemens as well.

While happy with the precision capabilities, EMAG’s focus on future development is trying to decrease the downtime between producing components. “On the automation and the part handling, the challenge is you want the machine to run and make parts all the time, right? But once a part is done, you have to take it out and put the other in,” Loetzner says. “Those non-productive times are the biggest enemies.”

EMAG reduces those times partly by use of the Japanese chaku chaku principle. Meaning “loading loading,” the idea is to bring various process steps as close together as possible to improve the speed between the processes. EMAG’s vertical machining centers not only fill a much smaller footprint on the plant floor, they also improve chip flow. Also, all of EMAG’s machines are self-loading, with a servo-controlled shuttle traveling through the machine, but not through the work envelope, Loetzner notes.

“While we have shown the industry we can master any part to highest precision, over the last five years we’ve been more and more focused on tightening non-productive time,” Loetzner says. At IMTS in Chicago in September, 2012, EMAG showed a new machine generation that significantly reduces the non-value add times. “Our chip-to-chip time was between 6 and 7 seconds for typical automotive gear,” Loetzner says. “Now it would be a second or less.”

Oilfield Technology: The Perfect Machining of Threads On Delivery Pipes and Casings

Whether we are talking about North America, Asia or Russia, within the oil and gas industry, there is a spirit of optimism. Geological discoveries have led to a massive increase in the estimated reserves in many countries. Along with these discoveries, the potential for the use of innovative technologies has also increased. According to the expert estimates, oil production in the Gulf of Mexico alone will rise from the present 1.3 million to 1.7 million barrels a day during the next decade, with demands for the highly sophisticated technological equipment required to accomplish it increasing as well. Two examples are delivery pipes and casings.  To create the connection safely and in perfect alignment depends on the threads on the pipe ends. With its USC turning machines, the specialists from EMAG Leipzig have not only created a tool that specializes in this application – and one that has perfected the production sequence for these threads – but also developed complete solutions that guarantee component quality and process integrity.

Economic key performance indicators for suppliers to the oil and natural gas industry change rapidly. An impressive example of this is found in the USA. The USA hopes to reduce its dependence on oil imports and instead invest heavily in new technology. An indicator, for the US, are imports of equipment technology for the American oil and gas industry, which the U.S. Department of Commerce for 2012 show an increase of 33 percent, compared to the previous year. The experts also expect a production boom in South America and Asia. For Brazil, the foreign trade experts at Germany Trade and Invest (GTAI) predict a “high level of growth in new reserves“. And on the other side of the globe, the investment volume in the oil and gas sector of Vietnam alone has reached 40 billion USD, according to GTAI.

The experts at EMAG Leipzig are aware that this extraordinary dynamic has a direct impact on the production of the required technology. For decades, the machine builders at Leipzig have been specializing in the machining of delivery pipes and casings for the oil and gas industry. Many users can no longer do without their special know-how in demanding thread production. Frank Schiffler, Head of Sales, fills us in on the background: “We are talking about a gigantic production output. One steel mill produces up to 2 million metric tons of pipes per annum. Component quality is paramount for these because the pipe threads have to be totally leak-proof and must carry the enormous total weight of pipe and oil during the delivery. The machining centers used must ensure that the quality and efficiency of the threads produced is 100%.”

Flexible solutions for the production of pipes

The USC series from EMAG Leipzig Maschinenfabrik represents an extraordinary, sophisticated solution for this particular production requirement. Flexibility is very important in the construction of these turning machines. Not only do the different machine sizes allow for the complete-machining of different sizes of pipes with external and internal threads to API and GOST standards, they can also cut all proprietary threads. “The larger oil field technology producers have their own thread standards.  We can adjust our machines perfectly to their demands“, explains Mr. Schiffler. For instance, all workholding and centering equipment is configured to suit individual requirements. The same applies to all automation components. As a result, the customer has an extremely fast production solution that automatically loads and unloads the components in 12 to 20 seconds (depending on pipe size and thread type), then carries out the 3-part threading process – from facing to chamfering and finally threadcutting. The output ratio therefore increases enormously, compared with that of traditional turning machines.

However, there are two important factors that must be taken into account when machining threads on delivery pipes and casings: processing quality and process integrity. The quality is guaranteed by a perfectly adjusted machine, with proven EMAG technology and the know-how of the speciality machine builders from Leipzig come together. The whole process benefits from the following important design details:

• The machine base is made with Mineralit (a polymer concrete) and guarantees the stability and the vibration-resistance of all machine components.
• The main drive forms an integral part of the spindle unit. Its frequency-controlled, maintenance-free AC asynchronous motor provides a high torque rate, which allows for the simultaneous machining of both ends of the pipe.
• The pipes are safely clamped in front and rear chucks that – depending on workpiece requirements – can be actuated pneumatically, hydraulically or mechanically.
• The pipe ends are stabilized during the machining process by the insertion of vibration-reducing mandrels, resulting in the highest possible precision.

“This quality is a feature of all our USC series machines,” acknowledges Mr. Schiffler. Depending on the machine used, the max pipe diameter can be any dimension from 2⅜” to 20”.

Complete solutions guarantee process integrity

When faced with high production rates, fast machining processes and expensive pipe blanks, machine downtimes are particularly costly for the manufacturer. For this very reason, the process integrity of these machines is another key development area in Leipzig. “We design complete solutions for our customers, who – in turn – benefit from the quality of the EMAG components“, explains Mr. Schiffler. “In addition to that, we integrate, for instance, measuring stations, crack detection equipment, embossing and plating units and, of course, a monitoring system that covers all components. At the end, what we supply is a production system that guarantees the greatest possible degree of process integrity.“ Of similar importance in this context is the worldwide service presence of the specialists. Not only are both user and maintenance staff trained to perfection, a 24-hour 365-day telephone service is also available. This ensures that possible machine downtimes are reduced to an absolute minimum.

Projects from A to Z

How do the special machine manufacturers assess their market opportunities over the next few years? Mr. Schiffler’s judgement on the market’s dynamic is a positive one: “We already are the market leader in machines for the threading of oil and gas pipes; and we intend to further extend this position.“ One formula for success in this field is the famous “Made in Germany“ – which is a sign for quality. Over 70 percent of the machine components are made and assembled at EMAG in Germany. Every customer comes to Leipzig for the machine acceptance, where the first test run, using the actual pipe blanks, is carried out. Only then will the machine be installed at the production site. “Our particular quality of service kicks in long before the machine is built, or the central claim made by EMAG Leipzig would not be a valid one. Our name stands for projects that are carried through to perfection from A to Z, and that represent all-round solutions.“

Small Grinding Center Offers Big Productivity Boost

Automobile manufacturers all over the world were able to enjoy an increase in their sales figures, this year! The biggest increases were experienced in the USA, China, India and Russia. However, the rapidly increasing number of vehicles built also brought some production challenges – for instance, the sub-contractors must deal with the increasing output levels and also need to ensure that process safety and component quality do not suffer. In fact, even the smallest components with complex geometries must be produced with increasing levels of precision.  In the development of the VLC 100 G Vertical Grinding Center from EMAG, our grinding specialists have made sure that the machine concept offers efficient, error-free machining processes for the production of small chucked components.

Small chucked components are typically produced in large quantities. The demand for components, such as gearwheels, planetary gears, chain gears and flanged components for cars, for instance, have necessary quantities that typically go into the millions; and short cycle times in the production of these components have become mandatory. For instance, the internal contour of a gearwheel must be ground in the shortest possible time and the machine’s workholding unit must be loaded with a new workpiece just as quickly. In many production environments, this represents a critical moment, because the idle time is commonly a decisive factor in establishing the economic viability of the whole process.

Automatic loading scores heavily

High output levels – short cycle times. This is exactly why the VLC 100 G Vertical Grinding Center from EMAG, for small chucked components with a maximum diameter of 100 mm, was developed. The machine utilizes its onboard pick-up system to load itself. And while one workpiece is being machined, the operator – or the automation system – is putting the raw-parts on the conveyor belt. This reduces idle time and increases output rates. Another benefit is the vertical machining concept; the design ensures that the grinding sludge falls to the bottom of the machine unhindered, where it is then transported out of the machine. (Click HERE for a video detailing the VLC 100 G Vertical Grinding Center)

Quality control is integrated

Measuring processes can also be integrated into the machine, making quality control an integral part of the whole process. The measuring probe is located between the machining area and pick-up station, where it is protected from contamination.

In use are two different grinding wheels

An important feature of the VLC 100 G is that it offers the possibility to use two grinding spindles, which can be used to perform different grinding operations, or to handle both rough- and finish-grinding work.  In other words, the first wheel performs the “rough” job of removing excess material from the raw-part at high feedrates (the CBN wheel is specially designed to absorb the necessary forces), while the second wheel (with different specifications) takes over the finishing work to guarantee a perfect surface finish on even the most challenging geometries. With the help of this intelligent tooling combination, EMAG design engineers have succeeded in drastically reducing the grinding time of even very complex components. “For the removal of large amounts, two wheels offer a shorter cycle time than one, with the first wheel designed to do the rough-grinding and the second one in charge of finish-grinding work,” explains Dr. Guido Hegener,  Managing Director of EMAG Salach Maschinenfabrik GmbH in Germany.

A convincing machine concept

The combination of fast loading and efficient grinding processes leads to a very compelling machine concept. The VLC 100 G works very well with the dynamic developments in automotive production. Now, with the rapid increase in required quantities, the demand is for new machine concepts that can be integrated into existing production without any problem. With the VLC 100 G, two features enable it to be integrated without any problems. “Programming the workpieces with our new EMAG NAVIGATOR software is simple and intuitive, saving valuable setup time. For many production environments, this is an advantage that should not be underrated,“ confirms Dr. Hegener. Furthermore, the exceptionally small footprint for the VLC 100 G should make the work of every production planner easier. The stand-alone machine occupies about 4.5 square meters (48 square feet), making sure that the growth of a production facility of this kind will not be limited by floor space requirements.

The advantages of the VLC 100 G

• Compact grinder with the highest precision
• The machine can accommodate both internal and external grinding spindles.
• Integral automation, short travel times = short chip-to-chip times
• Vertical machining = unhindered chip flow, with the grinding sludge falling to the bottom
• Optimal access = fast setups
• Great process safety through the use of an optional measuring probe
