ABSTRACT:
The coordinate measuring machine comprises a basic frame structure including a bearing portion having a steel track with a crossbeam support for traveling on the steel track which carries a spindle sleeve. At least one of the frame structure parts comprises a cast resin concrete with a steel track embedded in the cast part. The composition of the synthetic resin concrete at least in the zones adjacent the steel track is such that the coefficient of thermal expansion of the concrete is substantially equal to that of the steel track.
