Vacuum Chambers and Special Components Introduction Vacuum mechanics is the strongest line of the VACOM product range. We see the greatest challenges in the manufacturing of special components. The requirements of vacuum applications especially in the field of high-technology exceed the requirements of traditional mechanical engineering. A weld seam not only has to fulfill the requirements for mechanical stability but also needs to be gas tight. The used materials have to be characterized by low outgassing rates and low gas permeation. It is not sufficient that the electropolishing process...

Vacuum Chambers and Special Components Design Adjustment of Focal Point The alignment of ports and flanges to a defined focal point can be of essential importance for many specific applications in vacuum technology. The figure on the left shows a component with numerous ports with the following technological requirements:  Alignment of the ports to three focal points  Many overlapping weld seams  The chronological order of the different welding steps, so that the part is weldable and can be clamped on the milling machine in the intermediate steps  Uniform weld seams in order to maintain...

Vacuum Chambers and Special Components 1 Mechanical Production Precision Turning and Milling – Our Dimensions of Production Machining is one of our main focuses of our mechanical production. We have 3- and 5-axis precision milling centres available for the realization of your specific requirements. Thus, we are able to manufacture chambers with dimensions up to 1200 x 700 x 600 mm and chambers with diameters up to 500 mm. We realize larger dimensions for you after individual technical clarification. Our clamping and setting concepts are designed and optimized for the economical production...

Vacuum Chambers and Special Components Welding Technology Vacuum-Tight Welding We mainly join tube-flange and tube-tube connections manually using several welding processes to produce weld seams of high quality. We are experienced in welding stainless steels of  different qualities. Hereby particularly noteworthy are the materials 1.4301, 1.4307, 1.4404, 1.4435, 1.4429, 1.4541 and 1.4571. The emergence of virtual leaks is prevented by welding the components on the vacuum side. If this is not possible, we weld vacuum-tight on atmosphere side (not full connection) or use full penetration...

Vacuum Chambers and Special Components 1 Welding Technology Aluminium welding We already manufacture vacuum components of various aluminum alloys. New is that vacuum parts made of hardenable aluminum alloy 6060 and 6082 can now be joined using TIG welding. Aluminum offers numerous production-related advantages in contrast to the usually in vacuum technology used stainless steels 304, 316L and 316LN. For example, aluminium is easier to machine (higher chip thickness, higher feed rates). Major advantages of aluminum are:  Lower weight due to density 2.73 g / cm3  Absolutely not...
