Abstract
A scanning device for a machine for the automatic sharpening of broaching or reaming tools has a horizontal slide for receiving a tool to be sharpened and a vertical slide having at least one grinding spindle. A scanning finger which can be moved approximately vertically relative to the scanning device is provided for ascertaining the position of a particular tooth and is coupled with at least one member which emits displacement-dependent signals for triggering drive mechanisms for the machine slides. In order to enable a substantially arbitrary, yet precise, guidance of the scanning finger in order to ascertain dimensions which are of importance for the geometry of the tool, the scanning finger is attached on one of two slides which are displaceable at right angles relative to one another and a displacement pickup is associated with each slide for detecting the displacement distance from a position of rest traveled by respective slide.
