ABSTRACT:
In measuring apparatus, a workpiece-contacting probe is mounted on a probe-supporting assembly which is maintained at a constant temperature by bathing it with liquid. The liquid is supplied at a constant temperature by a heat exchanger system which also supplies liquid to hydrostatic bearings in the probe-supporting assembly. Before being measured, the workpieces are immersed in a bath which is maintained at a constant temperature. Liquid is fed into the immersion bath by a probe provided with liquid outlets which can be directed against selected areas of a submerged workpiece.
