Abstract
In the method, a tool is tested for an aligning fit or an imbalance in a tool spindle. The tool spindle is set into rotation. A light beam is used to check whether the tool wobbles. The tool spindle and the light beam are moved relative to one another until the light beam impinges on the area covered by the wobbling movement and a received signal generated from the light beam has an intermittent signal path for the first time. The then prevailing relative position between the tool spindle and the light beam is evaluated in respect of a non-aligning fit of the tool or in respect of a tool imbalance.
