ABSTRACT:
A measuring system for measuring the relative position of two machine parts of a processing machine includes a scale fastened at one end by means of screws to the slide of the machine. The other end of the scale is joined by means of an adhesive layer with one end of an expansion element. The other end of the expansion element is fastened in a similar manner by means of screws to the slide. For the compensation of thermally induced length changes of the scale, the expansion element is provided with a coefficient of thermal expansion substantially greater than that of the slide piece. Thermal expansion of the expansion element is dimensioned in such a way that the measuring length of the scale is preserved in an unaltered length in the event of temperature fluctuations by means of increased compressive forces applied by the expansion element to the scale.
