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.

Better component quality at a lower price? VL 5i, a vertical turning machine that is custom-made to fully meet the demands of the small and medium size manufacturing company.
With their VL 5i the machine tool specialists at EMAG have developed a comprehensive solution for small and medium size manufacturing companies. It can be used for small and large batch production, and complete-machines workpieces of up to 250 mm in diameter in a single setup. Flanges, gears, gear shafts and steering pinions can be machined with as much efficiency and to the same quality as brake disks or cams. The machine features a powerful 28 kW workspindle with a top torque of 300 Nm, plus a turret that accommodates turning as well as driven tools and has an impressively short indexing time of 2.2 s.
Drilling and milling operations can be incorporated by equipping some or all of the 12 turret stations with driven tools. The outstanding feature in this is the EMAG turret drive that combines high speeds with outstanding performance and a small space requirement. For instance, the diameter of the turret is only 360 mm but accommodates 12 stations and has a maximum torque rating of 45 Nm.
Flexible automation included
Proof of the outstanding quality of the VL 5i is, first of all, its integrated automation system. It uses a recirculating chain conveyor equipped with carrier prisms that deliver the raw-parts directly to a pick-up station for machining. This station is located behind the machining area, so the operator can – at any time – insert new raw-parts at the front of the machine. It is hard to imagine a more flexible and, at the same time, more universal solution for the automation of a machine tool.
Short travel times = short idle times
Another advantage of the VL 5i is its short idle times. Changing workpieces is a very fast process, because the distance between the loading position and the machining position is only 550 mm. The importance the EMAG turning specialists attach to the machine’s efficiency can also be seen in the design of the guideways. They are located outside the machining area, where they are protected against chips and dirt. This reduces the maintenance effort and makes the machine less susceptible to breakdowns. The machine can also be equipped with an optional measuring station, located outside the machining area. Here the component is measured on its way from the tooling zone to the unloading station, while still in its original clamping position. The measuring results are not distorted by the entrance of chips, as the vertical turning operation provides for ideal chip flow conditions.
Energy efficiency is very important
The sustainable use of energy and resources completes the picture of an engineering solution that not only offers a small footprint but also eliminates unnecessary design details which is the reason why the machine builders at EMAG can offer this machine at an advantageous price-performance ratio.

High component quality with low production costs is required in many applications involving machining chucked parts. At IMTS, September 10 – 15, 2012 in Chicago, EMAG will be showing these solutions which combine these requirements. One of the highlights at the show will be the introduction of the brand new VL 2 P, a vertical pick-up turning machine which operates using pendulum technology.
Whether you want to manufacture small chuck parts or larger components, the machining processes must ensure accurate component geometry while also guaranteeing low component costs. These requirements and more are met with the VL 2 P and VL 5i vertical turning machines as well as the VSC 400 DDS turning and grinding center from EMAG. The advance in productivity is provided by the EMAG design of these machines with the integrated pick-up automation and a machine body made of polymer concrete as well as the vertical design which ensures perfect chip flow conditions.
VL 2 P: Swinging to success
Workpieces up to 100 mm in diameter can be machined in full on the innovative VL 2 P, a two-spindle turning machine. The machine has two spindles because while one workpiece is being machined, the second spindle automatically loads itself using the pick-up method. This means that the next raw part is immediately ready for machining, resulting in extremely short chip-to-chip times. The focus during the design of this machine was efficiency and eliminating idle times. The VL 2 P also has an incredibly small footprint due to its compact design, which helps decrease the chip-to-chip times. See it in action at IMTS 2012 HERE.
VL 5i: Short idle times, perfect automation
The VL 5i turning machine is a universal solution for production companies. It can completely machine workpieces of up to 250 mm in diameter in a single clamping operation. In addition to the powerful pick-up working spindle with a rating of 28 kW and a torque of 300 Nm, the machine also has an automation system with a revolving belt which contains drag frames. The machine could be described as being self-automated, which means that new raw parts can be positioned and finished parts removed at any time. Another strength of the VL 5i is its short idle times because the distance between the loading and the machining positions is just 550 mm.
VSC 400 DDS: Grinding and turning combined
The VSC 400 DDS vertical grinding and turning center combines a range of processes and guarantees extremely cost-effective processes in the production of complex chuck parts with a diameter of up to 400 mm. Within a single clamping operation, the center can complete scroll-free turning and hard turning as well as subsequent grinding processes. Grinding is only used where quality and process reliability demands it. The center can also be fitted with drilling tools or hardening modules to suit the required machining task. Even measuring tasks can be integrated.
