Measurement devices are proposed for the relative thermal displacement between the grinding wheel and the workpiece, and for the thermal displacement of the wheel spindle itself during rotation of the wheel spindle. Then by separating the thermal deformation of the wheel spindle and the wheel spindle head from the relative thermal deformation between the wheel spindle and workpiece, the thermal deformation of the grinding machine is evaluated in detail. The following results are obtained. (1) The grinding wheel spindle and the wheel spindle head cause the thermal displacement in various directions. (2) A percentage of the influence of the wheel spindle and the wheel spindle head in the relative thermal deformation is different depending upon the direction of the thermal displacement.
