Positioning items in a vacuum is a particular challenge. Only certain materials, components and lubricants meet the requirements in terms of low gas emissions. Often, it is not possible to use liquid lubricants. The bake-out process also puts a great deal of pressure on the positioning system; the thermal stresses which occur at temperatures up to 140°C must be taken into account. All the parts we produce are vacuum-compatible, cleaned separately after production and assembled in a clean room The choice of materials is restricted even further for nonmagnetic systems.
We provide a wide range of solutions both for highly demanding UHV systems and for nonmagnetic assemblies. We have racked up more than a decade of experience in constructing and producing these challenging positioning systems, and boast special expertise in tribology and lubrication in dry, oxygen-free atmospheres such as vacuums and ultra-pure nitrogen.
