Machine component positioning device e.g. for precision machine tool, has linear guidance of positioned machine component relative to second machine component provided by linearly adjustable positioning elements
The positioning device (1) has 3 separate positioning elements (4), acting on the machine component (2) at different points and each exhibiting a linear length variation in a respective working direction. The parallel guidance of the machine component relative to a second machine component is provided by the torsional rigidity of at least 2 of the positioning elements and the limited pivot movement allowed by the pivot mountings for the positioning elements. An Independent claim for a precision machine tool provided with a positioning device is also included.
