  ... of the machines. In order to prevent changes in the tension of the guideway systems caused by expansion, a special system is used in which ... of magnetic force and gravity (Fig. 29). Fig. 29: Constant-tension guideway system of Werth measuring stages. Moreover, this guideway system also minimizes friction, reducing backlash on reversal as ... stability of the system is further supported by the fact that the

  Bridge-Type Coordinate Measuring Machines
  ... Measuring Machines Bridge-Type Coordinate Measuring Machines For higher precision requirements and larger measuring ranges, the mechanical guideway of the desktop model is replaced by systems with air bearings. The high-precision guideways are typically made of a natural hard stone material like granite. All moving components glide along these surfaces on an air cushion of only a ...

  ... and higher temperature stability, these components are made of aluminum (with high thermal conductivity), and special constant-tension guideway systems are used (see Fig. 29, p. 47). Today these machines are usually fully automated in all three axes, and their measuring range is ...

  ... with moving table and fixed bridge (Werth VideoCheck® 400×400×400). Through appropriate design measures, a constant prestress of the entire guideway system can be attained similar to the machines described above. A fixed-bridge construction is optimally suited to machines with ... uncertainty values. This is supported by manufacturing the bridge in a single piece with close tolerances. No subsequent adjustment of the

  ... expansion coefficient. Thermally induced deformation of the machine is thus minimized. All of the machine’s sensitive components (its scales, guideways, etc.) are encapsulated or covered so that it can be installed in rough manufacturing environments. These components are designed with an eye ...
