Abstract:
A position measuring device for use on a machine tool includes a scale section that can be scanned by way of a scanner device and serves to detect a position of a first component of the machine tool in relation to a second component of the machine tool, which is movable in relation to the first component, when the scale section is arranged on the first component and the scanner device is arranged on the second component, and at least one holding element as a constituent of an indirect attachment for indirectly attaching the scale section to the first component of the machine tool. A material of the at least one holding element has a thermal expansion coefficient that is less than a thermal expansion coefficient of a material of the first component of the machine tool.
