Dear readers,

What does the word Bavaria conjure up in your mind? Probably idyllic landscapes with green Alpine meadows, magnifi cent lakes, and breathtaking mountain views – not to mention the traditional get-together at the Oktoberfest or an inviting beer garden. Of course, this isn’t wrong, but it fails to take into account that this state, like other areas of Germany, has been transformed in recent decades from an agricultural location into a high-tech region and a business partner with a global presence. Bavaria’s economic and technological strength is evident not just in the urban regions, but also in rural areas where many highly innovative medium-sized companies have chosen to settle. Within the metalworking industry, these companies show a high level of technology – frequently as a result of skillfully fi lling niches. We will be introducing you to some of them in this issue of our magazine – including a small contract manufacturer from Allgäu that works mainly for the automotive industry; a

Siemens AG Franconian machine shop whose very large milled parts have established the company as a valued partner in the gas turbine construction, reactor technology and aerospace industries; and a highly specialized company based in Berchtesgadener Land whose customized show lasers are responsible for spectacular lighting effects at the concerts of international stars staged all over the world. With Sinumerik 828D and 840D sl, Siemens offers all of these companies a made-to-measure CNC that enables them to produce even the most complex parts with maximum productivity. They are assisted by ShopMill and ShopTurn, the intuitive machine shop software for milling and turning. It goes without saying that all these successful medium-sized businesses need highly-qualifi ed employees to achieve the required precision and perfection on their machine tools, and here too, Bavaria has a lot to offer – as a large number of Siemens’ training partners will confi rm. I hope you enjoy this issue of CNC4you and gain new insights into Bavaria’s strengths. Come and learn more about the Sinumerik’s performance at our booth C12 in hall 4 at the AMB. I look forward to seeing you!

Complex workpieces for show lasers produced using 3+2-axis machining Exciting Effects Arctos

Show lasers by Arctos enjoy a global reputation thanks to their impressive effects. For the production of its in-house inventions, the company uses a fi ve-axis milling center with a Sinumerik controller. In addition to precise drilling and milling operations, it also features fast and easy programming, graphically-animated simulation and process monitoring via text message.

ASS AG relies on Sinumerik and ShopMill for the production of automatic sewing units

A. Dudy - Fotolia.com The Perfect Stitch

The development and construction of automatic sewing units requires the highest level of precision. For that reason, ASS AG has upgraded its shop fl oor with a three- axis CNC milling machine and a Sinumerik 828D with the ShopMill operating software. Although the employees had no previous experience with Sinumerik controllers, they were able to use the machines in production within just a few days. In all probability, everyone of us has come into frequent contact with products made on automatic sewing units produced by Automated Sewing Systems (ASS) AG. As a specialist in the construc- tion of automatic units, the company based in Bessenbach, Germany, supplies manufacturers in the textile industry all over the world. What started out with one serging machine has since grown into a product line comprising more than 20 automatic sewing units. Serging systems overlock the edges of skirt and trouser panels and, depending on the confi guration, are fi tted with a second or third sewing head that enables articles of clothing to be sewn completely in a single operation. The line is supplemented by specialized automatic units – for exam- ple, for sewing trouser pockets or zippers. In this case, the >>

Jürgen Ries from Siemens at the Sinumerik 840D sl Quickly and easily programmed with ShopTurn Stübing is equally enthusiastic about the horizontal turning machines. The product manager describes the benefi ts: “The interaction between driven machine tools and controller is impressive. It’s so much easier to program tasks such as milling and engraving of wrench sizes.” With the existing milling cycles, front- face machining can also be programmed and milled very quickly on the turning machine. The cycles can also be used for machining lateral surfaces, as long as the machine has a y-axis, and are so uni- versally usable that the company pro- duces small milled parts on the turning machine if the milling machines are working to full capacity with other orders.

Sinumerik 808D completes the Sinumerik family at the lower end CNC for Entry-Level Users

With the Sinumerik 808D, Siemens has developed a CNC for the lower perfor- mance range. The compact, user- friendly entry-level solution replaces the Sinumerik 802S and is used for simple turning and milling applica- tions. Its simplicity also makes it interesting for the shop fl oor sector. The CNC is particularly suitable for use with standard machines in the lower performance range, as it includes only the functions that the user in this environment really needs. Sinumerik Operate Basic provides a very easy and clear-to-understand graphical user interface. Thanks to Sinumerik MDynamics, however, the 808D also scores highly on precision and productivity. The onboard ports, which eliminate complicated wiring in the control cabinet, are yet another point in the new CNC’s favor. < Siemens AG
