Welding:

In the welding area, manual arc welding, TIG, MIG and MAG welding are used to weld unalloyed, low-alloyed and high-alloyed steels, aluminum, high-nickel materials and other special materials.

Single parts and series can be produced according to customer requirements. The welding staff is certified according to ISO 9606 and the testing staff is certified in accordance with EN 473.

Other certificates to which we are authorized to fabricate are DIN 18800-7 Class E, EN 1090-2 EXC4, EN 1090-3 EXC4 and AD 2000 leaflet HP0.

Assembly of components:

On more than 400m2 we assemble smaller sub-assemblies, single parts or series, modules or complete plants, including electrical work and necessary testing.

We hope this article has aroused your interest and look forward to your feedback. If you have any questions about an area, please feel free to contact us and we will get back to you.

Pushing the Limits II

In addition to the new development of small optics ion beam figuring by means of a 40µm ion beam last year (for more Informations click here), we are currently extending the range of our ion beam sources to the processing of large optics.

In addition to our ion beam processing systems for machinable optical diameters from 1mm to 2000mm, which are already in use worldwide, this system opens up the range for machinable diameters above 2000mm with a high volume removal rate.

Our new tool, currently in commissioning, delivers an ion beam width in the range of 120mm to 200mm (half width of the Gaussian shape) at an extraction voltage in the range of 0.6 kV to 1.5kV with the working gas argon. First plasma, beam and material removal tests are planned for the next weeks.

We will keep you informed.

NTG is also active in the service sector of contract manufacturing in the areas of turning, milling, welding, component assembly and special machine construction. The main focus is on stainless steel and aluminum processing. However, other materials such as titanium, tantalum, inconel, zircaloy, ceramics and plastics can also be processed with our modern machinery.

Turning:

In the field of turning, we have multi-functional machines, as well as machines for CNC turning, turning-manual, face turning and center turning, allowing us to machine components up to 2,500 mm in diameter and 3,550 mm in length.

Milling:

In the field of milling, we include CNC controlled and manual boring mills, CNC milling machines with 3, 4 and 5 axes and 5 axis CNC milling machines with rotary option. We can machine components up to 20,000 kg and a size of (X/Y/Z) 7,500 mm x 1,500 mm x 4,000 mm.

Alumina ceramic chambers are widely used in accelerator units for injection, fast extraction and beam excitation. These components are placed in fast pulsed (range of nanosecond) deflector magnets as kicker, buncher or scanner application. Unlike metallic components, ceramic components avoid shielding the rapidly changing external magnetic fields. Furthermore, metallic tubes would heat up considerably due to counter-induced eddy currents. To prevent static charges and the emission of secondary electrons on the ceramic surface, the inner surfaces of the ceramic chambers can be coated with a high-resistance thin layer.

The requirements for these components are: Sufficient mechanical strength against atmospheric pressure and resilience through installation and operation. Techniques in this field have been further developed, following the requirements in special applications. For example, a method has been developed to make the transitions between the material zones inside the chambers as smooth as possible. This is of particular interest in the field of electron accelerators, where impedance changes are to be avoided.

The sample images show a ceramic chamber with a smooth transition from a polygonal octagonal contour at the flange entrance to the inner racetrack shape of the ceramic. Client: SigmaPhi, Location: Soleil Electron Synchrotron near Paris – Voilà!

The production area in Hall 1 of NTG’s main building is brightly illuminated.
288 old fluorescent tubes with conventional ballast (CCG) of 36 watts each and 7 watts of power loss for the CCG have been replaced by 121 new LED luminaires with daylight-dependent control of 53.1 watts each.

With this measure, an annual electricity saving of almost 75,000 kWh can be achieved. In addition to the associated, not inconsiderable cost savings and significantly improved illumination of the production hall, we are also pleased about an annual CO2 reduction of over 20 tons.
With the new LED lighting, we are making another small contribution on our way to energy neutrality. We started this journey in 2009 with the installation of NTG’s own solar plant, which fortunately exceeded the limit of 2 million kilowatt hours generated in 2020. Further steps will follow!
