Abstract
The invention relates to a device for checking for tool breakage in machine tools having a sensor for sensing a clamped tool before and after a machining operation and an electronic device for evaluation of the measurement detected by the sensor. According to the invention the sensor is constructed as a moveable feeler rod (5) and in each measuring operation is pressed against the tool tip with an adjustable force independent of the length of the tool (7) concerned. A device for determining the respective measuring position of the feeler rod (5) provides the data for the evaluation.
