High-Precision Positioning of Inspection Items in the X-Ray Beam
CT systems with rotary tables and angle encoder modules with roller bearings In the domain of non-destructive materials testing, computed tomography (CT) is a technology that provides a unique three-dimensional view of inspection items. For example, it permits precise geometrical measurement of the inner structures of components, comparison with CAD data and the detection of […]
High-Precision Drives for the Optical Industry
Schüssler-Technik in Pforzheim, Germany, is divided into two divisions. The first division manufactures primarily milling, bending and laser soldering machines for the manufacture of eyeglass frames. The second is occupied with the R&D and sale of direct drives.
A New Dimension in the Nanometer Range
The trend in the semiconductor industry to ever higher levels of integration and, with it, to continuously finer structures, calls for measuring devices with high resolution for positioning to the nanometer in the manufacturing process and in measuring and inspection technology. Measuring error due to guideway influences and thermal expansion, which at present cannot be compensated by computation, can be ascertained by a new measuring device and therefore significantly reduced.
