Mechanical Manufacture
The area of Mechanical Manufacture is subdivided into the following shops:
Machining of prismatic workpieces
In the Mechanical Engineering and the Precision Mechanics Shops, both conventional and computer-controlled (CNC) multi-axis milling machines – in part with automatic tool changing units – are available to machine up to five sides of a workpiece up to a volume of about one cubic metre at one setting. A horizontal boring mill, column-type and bench-type drilling machines and a radial drilling machine with coordinate drilling table supplement the milling machinery. A CNC engraver serves to provide plane, cylindrical and conical surfaces of the fabricated parts with inscriptions or graphical symbols using a graver.
Machining of rotationally symmetrical workpieces
Conventional and CNC drilling machines of different sizes can be used in the Turning Shop and in the Precision Mechanics Shop to fabricate workpieces with very difficult geometries. The CNC milling machines have up to three turrets which are equipped with driven tools and thus can carry out not only turning but also milling, boring, counterboring and thread cutting operations in parallel and orthogonal to the axis of rotation at one setting.
Forming, joining
In addition to hydraulic sheet shears for the cutting of sheet steel up to a thickness of 10 mm and a universal hydraulic assay press with a maximum pressing force of 560 kN, a sheet rolling machine, a profile rolling machine and two folding machines are available for sheet steel machining..
The Welding Shop carries out all the joining work for the fabrication and repair of experimentation and operating facilities, in most cases on the spot during fabrication but also during assembly in the laboratories..
These are:
MAG (metal active gas) welding of high-carbon and low-alloy steels in general structural steel engineering,
TIG (tungsten inert gas) welding of aluminium materials,
plasma and microplasma jet welding of stainless steel or thin-walled workpieces, respectively,
arc welding with stick electrode for welds having to meet high optical demands,
spot welding for punctiform joints, and
hard- and soft-soldering.
With the aid of a helium leak indicator, welds on vacuum equipment can be checked for tightness.
