ABSTRACT:
The invention concerns a device for examining the precision of motion of a working spindle of an NC-controlled machine tool along a circular path for producing circular cylindrical surfaces on workpieces, comprising a first device part which can be coaxially mounted to the working spindle, a second device part which can be positioned on a machine table, which receives a workpiece to be processed, coaxially to the axis of a circular cylindrical surface to be produced on the workpiece, an electronic measuring value sensor which extends radially with respect to the axes of working spindle and circular cylindrical surface and is hinged to both device parts, and a shaft encoder which is rotatably disposed in the second device part coaxial relative to the axis of the circular cylindrical surface to be produced to determine the angular position of the measuring value sensor, wherein the measuring value sensor is held on one of the two device parts such that it can be adjusted and fixed transversely to the axes of the working spindle and the circular cylindrical surface.
