Abstract: A measuring device includes a base body, and a measuring head which is movable between a rest position and a measuring position. The measuring device also includes an apparatus for moving the measuring head from the rest position into the measuring position, and a stop for limiting the motion of the measuring head from the rest position into the measuring position. A motorized drive unit for adjusting the position of the stop is operatively associated with the stop in such a way that the measuring position is adjustable, and a control unit is provided for activating the drive unit.

Abstract: Measuring device for in-process measurement of test specimens during a machining process on a machine tool, in particular a grinding machine, has a measuring head connected pivotably about a first pivot axis to a base body of the measuring device via a linkage, for providing an apparatus for pivoting measuring head in and out of a measuring position. Linkage has a first linkage element and a second linkage element arranged pivotably about first pivot axis. A third linkage element is connected pivotably about a second pivot axis to the end of second linkage element facing away from first pivot axis. A fourth linkage element is connected pivotably about a third pivot axis to the end of third linkage element facing away from second pivot axis, fourth linkage element being connected pivotably about a fourth pivot axis to first linkage element at a distance from third pivot axis.
